Abstract Introduction The aim was to evaluate the feasibility and quality of chest compressions (CCs) performed by police officers on a victim wearing a bulletproof vest as well as analyze the time taken to remove the vest. Methods Ten officers conducted two 5‐min cardiopulmonary resuscitation (CPR) trials. Trial 1: on a dummy wearing bulletproof vest (CPR‐VEST)/Trial 2: bare‐torso dummy (CPR‐NO). Results CC's quality and the timed vest removal. Results show that CC's quality was a median of 90% in CPR‐VEST and 99% in CPR‐NO (p = 0.08). There were significantly poorer results in CPR‐VEST in CC with correct recoil (CPR‐VEST: 12%, CPR‐NO: 10%, and p = 0.04) and rate (CPR‐VEST: 82%, CPR‐NO: 97%, and p = 0.01). The bulletproof vest removal time was 9.45 ± 1.33 s. Conclusion The removal of the vest is prioritized to facilitate CPR. CC over the vest is performed with similar quality levels to standard CPR, supporting the immediate initiation of CPR in special circumstances where the vest cannot be removed.

Abstract Background Trauma guidelines on spinal motion restriction (SMR) have changed drastically in recent years. An international group of experts explored whether consensus could be reached and if guidelines on SMR performed by trained lifeguards and prehospital EMS following in-water traumatic spinal cord injury (TSCI) should also be changed. Methods An international three-round Delphi process was conducted from October 2022 to November 2023. In Delphi round one, brainstorming resulted in an exhaustive list of recommendations for handling patients with suspected in-water TSCI. The list was also used to construct a preliminary flowchart for in-water SMR. In Delphi round two, three levels of agreement for each recommendation and the flowchart were established. Recommendations with strong consensus (≥ 85% agreement) underwent minor revisions and entered round three; recommendations with moderate consensus (75–85% agreement) underwent major revisions in two consecutive phases; and recommendations with weak consensus (

Objective: The aim of this study was to analyze the feasibility of a new resuscitation strategy in which breaths are provided during automated external defibrillator (AED) rhythm analysis, and to evaluate its impact on chest compressions (CC) quality and the peri-analysis time. Method: A randomized simulation study, comparing two cardiopulmonary resuscitations strategies, has been conducted: the standard strategy (S1) with strategy involving ventilation during AED analysis (S2). Thirty lifeguards have performed both strategies in a cross-over study design during 10 min of CPR. Results: The number of ventilations per 10 min increases from 47 (S1) to 72 (S2) (p

(1) Objective: The objective was to evaluate the quality of cardiopulmonary resuscitation (CPR, chest compressions and ventilations) when performed by a lone first responder on an infant victim via the over-the-head technique (OTH) with bag-mask ventilation in comparison with the standard lateral technique (LAT) position. (2) Methods: A randomized simulation crossover study in a baby manikin was conducted. A total of 28 first responders performed each of the techniques in two separate CPR tests (15:2 chest compressions:ventilations ratio), each lasting 5 min with a 15 min resting period. Quality CPR parameters were assessed using an app connected to the manikin. Those variables were related to chest compressions (CC: depth, rate, and correct CC point) and ventilation (number of effective ventilations). Additional variables included perceptions of the ease of execution of CPR. (3) Results: The median global CPR quality (integrated CC + V) was 82% with OTH and 79% with LAT (p = 0.94), whilst the CC quality was 88% with OTH and 80% with LAT (p = 0.67), and ventilation quality was 85% with OTH and 85% with LAT (p = 0.98). Correct chest release was significantly better with OTH (OTH: 92% vs. LAT: 62%, p < 0.001). There were no statistically significant differences in the remaining variables. Ease of execution perceptions favored the use of LAT over OTH. (4) Conclusions: Chest compressions and ventilations can be performed with similar quality in an infant manikin by lifeguards both with the standard recommended position (LAT) and the alternative OTH. This option could give some advantages in terms of optimal chest release between compressions. Our results should encourage the assessment of OTH in some selected cases and situations as when a lone rescuer is present and/or there are physical conditions that could impede the lateral rescue position.

(1) Objective: This study aimed to assess the evolution of the quality of ventilations of a group of rescuers after two training sessions by taking into account inspiration times. (2) Materials and Methods: A pilot simulation study was carried out with a sample of 10 lifeguard students. Two training sessions were held three weeks apart, in which CPR skills were trained by means of feedback tools. Participants performed three tests in pairs on a ResusciAnne QCPR® manikin connected to SkillReporter QCPR software, namely one pre-training test and one test after each training session. CPR was performed in pairs for two minutes and began with five rescue breaths. (3) Results: One training session was enough to improve chest compression quality (T0: 48%; IQR 17–77/T1: 83%; IQR 59–88; p = 0.022/T2: 79%; IQR 64–92; p = 0.002). The quality of the ventilations increased progressively in each training session without reaching high-quality results (T0: 0%; IQR 0–0/T2: 15%; IQR 8–27; p = 0.011). (4) Conclusion: A two-session training program focused on inspiratory times achieved significant improvements in the quality of bag-mask ventilations performed by lifeguard students. Training focused on the insufflation time of ventilations and not only on the volume seems to be an important factor in improving the quality of ventilations.

Introduction: Extracorporeal membrane oxygenation (ECMO) improves infant survival outcomes after cardiac arrest. If not feasible at the place of arrest, victims must be transported to a suitable room to perform ECMO while effective, sustained resuscitation maneuvers are performed. The objective of this simulation study was to compare the quality of resuscitation maneuvers on an infant manikin during simulated transfer on a stretcher (stretcher test) within a hospital versus standard stationary resuscitation maneuvers (control test). Methods: A total of 26 nursing students participated in a randomized crossover study. In pairs, the rescuers performed two 2 min tests, consisting of five rescue breaths followed by cycles of 15 compressions and two breaths. The analysis focused on CPR variables (chest compression and ventilation), CPR quality, the rate of perceived exertion and the distance covered. Results: No differences were observed in the chest compression quality variable (82 ± 10% versus 84 ± 11%, p = 0.15). However, significantly worse values were observed in the test for ventilation quality on the stretcher (18 ± 14%) compared to the control test (28 ± 21%), with a value of p = 0.030. Therefore, the overall CPR quality was worse in the stretcher test (50 ± 9%) than in the control test (56 ± 13%) (p = 0.025). Conclusions: Infant CPR performed by nursing students while walking alongside a moving stretcher is possible. However, in this model, the global CPR quality is less due to the low ventilation quality.

Coastal environments present dynamic challenges necessitating rapid and efficient responses during aquatic emergencies. Lifeguards, as pivotal links in the intervention chain, rely on various tools, with rescue time being paramount. The choice of fins, specifically long versus short ones, plays a critical role in optimizing lifeguard performance during rescues. This randomized cross-over study explores the impact of flipper size on ocean rescues, employing a sample of 14 lifeguards. Long fins (LFs) and short fins (SFs) were compared in terms of rescue time (RT) and physiological load (PL). Tests included ocean rescues without fins (R), with LF (R-LF), and with SF (R-SF). Variables recorded encompassed swim approach time, tow-in time, overall rescue time, perceived exertion rates (RPEs), and post-rescue lactate concentration. Long fins demonstrated superior performance in swim approach and tow-in times compared to both short fins and no fins (p < 0.001). Overall rescue time favored long fins significantly (p < 0.001), indicating their efficiency in practical ocean rescue scenarios. Physiologically, long fins induced lower perceived exertion in arms (p = 0.033) compared to short fins. Lactate concentrations post-rescue revealed no significant differences (p > 0.05). This study demonstrates that long fins significantly improve lifeguard performance during ocean rescues, reducing rescue times and alleviating arm fatigue.

Background: The integration of populations with various types of disabilities into basic life support (BLS) training programs could contribute to a potential increase in trained laypersons with BLS knowledge and, consequently, in survival rates. The objective of this study was to analyze the distinct educational methods which exist today on BLS for people with some type of specific disability, and to evaluate their impact on the quality of BLS maneuvers. Methods: A scoping review in which the different training strategies in BLS for people with distinctive disabilities were analyzed was carried out. Previous studies were sought and researched in MEDLINE, EMBASE, and the Cochrane Library from the beginning up to 4 August 2023. Results: A total of 14 studies were thoroughly analyzed. The BLS training strategies for people with disabilities were classified according to the following criteria: objective (training, content validation or analysis of learning barriers), target population (visual, hearing, physical disabilities or Down syndrome), training resources (training with/without adaptation), contents (BLS and use of the automated external defibrillator) and evaluation instrument (i.e., the simulation test and knowledge questionnaire). The variety of BLS training programs for such population is limited. Likewise, people with different disabilities are able to effectively learn BLS maneuvers, although with mixed results, mainly in those regarding the CPR quality. Conclusion: People with visual, hearing disabilities or Down syndrome are able to effectively learn BLS maneuvers.

Resumen: Introducción: el ideario popular, la diseminación a través de redes sociales o la «costumbre» han propiciado diversos mitos sobre el ahogamiento y los incidentes acuáticos que no están basados en evidencias y pueden tener efectos colaterales o limitan la comprensión de este fenómeno. El objetivo de este trabajo ha sido analizar el origen de los mitos más frecuentes relacionados con los incidentes acuáticos y ofrecer una perspectiva científica para su refutación. Materiales y métodos: doce expertos de las Ciencias de la Salud mediante un grupo nominal realizaron el cribado de conceptos en 3 fases: 1ª revisión literatura científica en PubMed en la que se abordasen conceptos erróneos u obsoletos relacionados a los incidentes en entornos acuáticos, 2ª el grupo elaboró un listado de 16 ítems susceptibles de analizar y 3ª se seleccionaron por consenso los mitos considerados más relevantes. Resultados: mediante consenso de expertos y las evidencias disponibles, 10 ítems fueron identificados como potenciales generadores de conceptos erróneos o mitos: el «corte de digestión», el uso de flotadores para prevenir el ahogamiento, hiperventilar antes de bucear, las implicaciones de la bandera roja en las playas, el proceso de ahogamiento, la principal función de los socorristas, orinar sobre picaduras de medusa, la terminología sobre ahogamiento y la reanimación de ahogados. Conclusión: en el ámbito del ahogamiento se sigue utilizando terminología obsoleta y existen creencias populares erróneas que deberían ser actualizadas y desmitificadas, ya que esto podría contribuir a disminuir la incidencia del ahogamiento y sus secuelas. Abstract: Introduction: Popular ideology, dissemination by social networks or the “custom” have fostered numerous myths about drowning and aquatic incidents that are not based on evidence and may be harmful or limit the understanding of this phenomenon. The aim of this paper is to analyze the origin of the most frequent myths related to aquatic incidents and to offer a scientific perspective for their refutation. Materials and methods: Twelve experts in the health sciences by means of a nominal group carried out the screening of concepts in three phases: 1st review of scientific literature in PUBMED in which erroneous or obsolete concepts related to incidents in aquatic environments were addressed, 2nd phase the nominal group elaborated an initial list of 16 items to be analyzed, 3rd phase the final list was refined to 1 by universal consensus of the nominal group. Results: Through expert consensus and available evidence, ten items were identified as potential generators of misconceptions or myths: the “digestion cut-off”, the use of floats to prevent drowning, hyperventilating before diving, the implications of the red flag on beaches, the drowning process, the main role of lifeguards, urinating on jellyfish stings, drowning terminology, and resuscitation of drowned persons. Conclusion: In the field of drowning, obsolete terminology continues to be used and there are erroneous popular beliefs that should be updated and demystified, as this could contribute to reduce the incidence of drowning and its sequelae.

Objectives: The International Liaison Committee on Resuscitation, in collaboration with drowning researchers from around the world, aimed to review the evidence addressing seven key resuscitation interventions: 1) immediate versus delayed resuscitation; (2) compression first versus ventilation first strategy; (3) compression-only CPR versus standard CPR (compressions and ventilations); (4) ventilation with and without equipment; (5) oxygen administration prior to hospital arrival; (6) automated external defibrillation first versus cardiopulmonary resuscitation first strategy; (7) public access defibrillation programmes. Methods: The review included studies relating to adults and children who had sustained a cardiac arrest following drowning with control groups and reported patient outcomes. Searches were run from database inception through to April 2023. The following databases were searched Ovid MEDLINE, Pre-Medline, Embase, Cochrane Central Register of Controlled Trials. Risk of bias was assessed using the ROBINS-I tool and the certainty of evidence was assessed using Grading of Recommendations Assessment, Development and Evaluation. The findings are reported as a narrative synthesis. Results: Three studies were included for two of the seven interventions (2,451 patients). No randomised controlled trials were identified. A retrospective observational study reported in-water resuscitation with rescue breaths improved patient outcomes compared to delayed resuscitation on land (n = 46 patients, very low certainty of evidence). The two observational studies (n = 2,405 patients), comparing compression-only with standard resuscitation, reported no difference for most outcomes. A statistically higher rate of survival to hospital discharge was reported for the standard resuscitation group in one of these studies (29.7% versus 18.1%, adjusted odds ratio 1.54 (95% confidence interval 1.01–2.36) (very low certainty of evidence). Conclusion: The key finding of this systematic review is the paucity of evidence, with control groups, to inform treatment guidelines for resuscitation in drowning.

Introduction: Laypeople should be trained in basic life support and traditional and innovative methodologies may help to obtain this goal. However, there is a knowledge gap about the ideal basic life support training methods. Smart glasses could have a role facilitating laypeople learning of basic life support. Aim: To analyze the potential impact on basic life support learning of a very brief training supported by smart glasses video communication. Methods: Twelve laypeople were basic life support tele-trained by means of smart glasses by an instructor in this pilot study. During training (assisted trough smart glasses) and after the training (unassisted) participants’ performance and quality of basic life support and automated external defibrillation procedure were assessed on a standardized simulated scenario. Results: After the training all participants were able to deliver good quality basic life support, with results comparable to those obtained when real time remotely guided by the instructor through the smart glasses. Mean chest compression rate was significantly higher when not guided (113 /min vs. 103 /min, p = 0.001). When not assisted, the participants spent less time delivering the sequential basic life support steps than when assisted while training. Conclusions: A very brief remote training supported by instructor and smart glasses seems to be an effective educational method that could facilitate basic life support learning by laypeople. This technology could be considered in cases where instructors are not locally available or in general in remote areas, providing basic internet connection is available. Smart glasses could also be useful for laypeople rolling-refreshers.

The aim of this study was to analyze the rescues carried out by surfers from Portugal and Spain, their knowledge of rescue and resuscitation and their perception and risk behavior while surfing. An online survey was conducted in 2048 surfers from Portugal and Spain, with questions regarding the demographic characteristics, experience, perception and risk behavior of the surfers; rescues attended by the surfers and surfer's knowledge and experience in rescue and resuscitation. Concerning the number of rescues carried out by surfers, 78.5% of the participants had to carry out at least one rescue in their lifetime. A significant association was found between the years of surfing experience, the surfing level and the number of rescues carried out (p

Drowning remains a prominent global pediatric health concern, necessitating preventive measures such as educational initiatives for children and caregivers. In this study, we aimed to assess the feasibility and educational effectiveness of an interactive puppet show centered on teaching water safety to children and parents. A 30 min original theater performance, featuring two actors and three puppets (a girl, a crab, and a lifeguard), was conducted. Subsequently, 185 children (aged 4 to 8) and their 160 parents (134 mothers and 26 fathers) participated in this quasi-experimental study. Pre- and post-show tests were administered to evaluate knowledge and behaviors regarding aquatic environments. Prior to the puppet show, 78% of the children exhibited basic aquatic competency. Only 33% considered swimming alone risky. Following the intervention, 81.6% of the children changed their perception of the risks of solo beach activities, showing improved knowledge regarding contacting an emergency number (from 63.2% to 98.9%, p < 0.001). The intervention increased parents’ intention to visit lifeguard-patrolled beaches and improved their CPR knowledge with regard to drowning victims by 58.8%. In conclusion, a drowning prevention puppet show positively impacted children and parents, potentially enhancing safety behaviors during water-related leisure activities, warranting its consideration part of comprehensive drowning prevention strategies.

Objective: To quantitatively assess the learning capacity of school children aged between 8-12 years in basic life support (theory and practice) after a feasible school training programme. Material and methods: Quasi-experimental study with a convenience sample of 567 pupils in 3rd and 5th year of Primary Education, and first year of Compulsory Secondary Education, from 3 public schools in Galicia. They received 2h (one theoretical and another practical) of basic life support training by their Physical Education teachers, as part of the school program. The children were evaluated by a theoretical test and a practical skill test that measured the quality of chest compressions, and assessed the performance of the basic life support sequence. Results: The level of knowledge increased with respect to the baseline, and was higher in the higher grades (P

The aim of this study was to compare the quality of standard infant CPR with CPR in motion (i.e., walking and running) via performing maneuvers and evacuating the infant from a beach. Thirteen trained lifeguards participated in a randomized crossover study. Each rescuer individually performed three tests of 2 min each. Five rescue breaths and cycles of 30 chest compressions followed by two breaths were performed. Mouth-to-mouth-and-nose ventilation was carried out, and chest compressions were performed using the two-fingers technique. The manikin was carried on the rescuer’s forearm with the head in the distal position. The analysis variables included compression, ventilation, and CPR quality variables, as well as physiological and effort parameters. Significantly lower compression quality values were obtained in running CPR versus standard CPR (53% ± 14% versus 63% ± 15%; p = 0.045). No significant differences were observed in ventilation or CPR quality. In conclusion, lifeguards in good physical condition can perform simulated infant CPR of a similar quality to that of CPR carried out on a victim who is lying down in a fixed position.

Objective To compare the effectiveness of 4-month rolling-refreshers and annual retraining in basic life support (BLS) on a sample of schoolchildren.Design Prospective longitudinal trial.Setting and participants Four hundred and seventy-two schoolchildren (8–12 years old).Interventions Schoolchildren were instructed in BLS and then split into the following three groups: control group (CG), standard group (SG) and rolling-refresher group (RRG). Their BLS skills were assessed within 1 week (T1) and 2 years later (T2). Moreover, CG did not receive any additional training; SG received one 50 min retraining session 1 year later; RRG participated in very brief (5 min) rolling-refreshers that were carried out every 4 months.Primary and secondary outcomes Hands-on skills of BLS sequence and cardiopulmonary resuscitation.Results BLS sequence performance was similar in all groups at T1, but SG and RRG followed the steps of the protocol in more proportion than CG at T2. When compared at T2, RRG showed higher proficiency than SG in checking safety, checking response, opening the airway and alerting emergency medical services. In addition, although the mean resuscitation quality was low in all groups, RRG participants reached a higher percentage of global quality cardiopulmonary resuscitation (CG: 16.4±24.1; SG: 25.3±28.8; RRG: 29.9%±29.4%), with a higher percentage of correct chest compressions by depth (CG: 3.9±11.8; SG: 10.8±22.7; RRG: 15.5±26.1 mm).Conclusions In 8-to-12-year-old schoolchildren, although annual 50 min retraining sessions help to maintain BLS performance, 4-month very brief rolling-refreshers were shown to be even more effective. Thus, we recommend implementing baseline BLS training at schools, with subsequently brief rolling-refreshers.

Smart glasses (SG) could be a breakthrough in emergency situations, so the aim of this work was to assess the potential benefits of teleassistance with smart glasses (SG) from a midwife to a lifeguard in a simulated, unplanned, out-of-hospital birth (OHB). Thirty-eight lifeguards were randomized into SG and control (CG) groups. All participants were required to act in a simulated imminent childbirth with a maternal–fetal simulator (PROMPT Flex, Laerdal, Norway). The CG acted autonomously, while the SG group was video-assisted by a midwife through SG (Vuzix Blade, New York, NY, USA). The video assistance was based on the OHB protocol, speaking and receiving images on the SG. The performance time, compliance with the protocol steps, and perceived performance with the SG were evaluated. The midwife’s video assistance with SG allowed 35% of the SG participants to perform the complete OHB protocol. No CG participant was able to perform it (p = 0.005). All OHB protocol variables were significantly better in the SG group than in the CG (p < 0.05). Telemedicine through video assistance with SG is feasible so that a lifeguard with no knowledge of childbirth care can act according to the recommendations in a simulated, unplanned, uncomplicated OHB. Communication with the midwife by speaking and sending images to the SG is perceived as an important benefit to the performance.

Background: There are few studies that analyze ventilation volume and pressure during CPR carried out on infants. The aim of this study was to evaluate the quality of the ventilations administered using a self-inflating bag with an endotracheal tube and a face mask in manikins. Methods: a quasi-experimental simulation study with a randomized case crossover design [endotracheal tube (ET) vs. face mask (FM)] was performed. Sixty participants who were previously trained nursing students participated in the study. The estimated air volumes breathed, and the pressure generated during each ventilation were assessed and the quality of the chest compressions was recorded. Results: the ET test presented a higher percentage of ventilations that reached the lungs (100% vs. 86%; p < 0.001), with adequate volume (60% vs. 28%; p < 0.001) in comparison to FM. Both tests presented peak pressures generated in the airway greater than 30 cm H2O (ET: 22% vs. FM: 31%; p = 0.03). Conclusions: performing quality CPR ventilations on an infant model is not an easy skill for trained nursing students. Both tests presented a significant incidence of excessive peak pressure during ventilations. Specific training, focused on quality of ventilations guided by a manometer attached to the self-inflating bag, must be considered in life support training for pediatric providers.

Background: Drowning is a significant public health issue with more than 320,000 deaths globally every year. These numbers are greatly underestimated, however, due to factors such as inadequate data collection, inconsistent categorization and failure to report in certain regions and cultures.The objective of this study was to develop a standardised drowning dictionary using a consensus-based approach. Through creation of this resource, improved clarity amongst stakeholders will be achieved and, as a result, so will our understanding of the drowning issue. Methodology: A list of terms and their definitions were created and sent to 16 drowning experts with a broad range of backgrounds across four continents and six languages. A review was conducted using a modified Delphi process over five rounds. A sixth round was done by an external panel evaluating the terms’ content validity. Results: The drowning dictionary included more than 350 terms. Of these, less than 10% had been previously published in peer review literature. On average, the external expert validity endorsing the dictionary shows a Scale Content Validity Index (S-CVI/Ave) of 0.91, exceeding the scientific recommended value. Ninety one percent of the items present an I-CVI (Level Content Validity Index) value considered acceptable (>0.78). The endorsement was not a universal agreement (S-CVI/UA: 0.44). Conclusion: The drowning dictionary provides a common language, and the authors envisage that its use will facilitate collaboration and comparison across prevention sectors, education, research, policy and treatment. The dictionary will be open to readers for discussion and further review at www.idra.world.

The aim of the study was to compare the quality of CPR (Q-CPR), as well as the perceived fatigue and hand pain in a prolonged infant cardiopulmonary resuscitation (CPR) performed by lifeguards using three different techniques. A randomized crossover simulation study was used to compare three infant CPR techniques: the two-finger technique (TF); the two-thumb encircling technique (TTE) and the two-thumb-fist technique (TTF). 58 professional lifeguards performed three tests in pairs during a 20-min period of CPR. The rescuers performed compressions and ventilations in 15:2 cycles and changed their roles every 2 min. The variables of analysis were CPR quality components, rate of perceived exertion (RPE) and hand pain with numeric rating scale (NRS). All three techniques showed high Q-CPR results (TF: 86 ± 9%/TTE: 88 ± 9%/TTF: 86 ± 16%), and the TTE showed higher values than the TF (p = 0.03). In the RPE analysis, fatigue was not excessive with any of the three techniques (values 20 min between 3.2 for TF, 2.4 in TTE and 2.5 in TTF on a 10-point scale). TF reached a higher value in RPE than TTF in all the intervals analyzed (p < 0.05). In relation to NRS, TF showed significantly higher values than TTE and TTF (NRS minute 20 = TF 4.7 vs. TTE 2.5 & TTF 2.2; p < 0.001). In conclusion, all techniques have been shown to be effective in high-quality infant CPR in a prolonged resuscitation carried out by lifeguards. However, the two-finger technique is less efficient in relation to fatigue and hand pain compared with two-thumb technique (TF vs. TTF, p = 0.01).

Resumen: Introducción: Los profesores pueden tener un papel esencial en la formación en reanimación cardiopulmonar básica (RCP-B) de los escolares. Sin embargo, se dispone de pocos datos acerca de la capacidad de aprendizaje de la RCP-B por estos profesionales. Objetivo: Evaluar de forma cuantitativa la calidad de la RCP-B realizada por profesores de colegios, tras un programa formativo breve y sencillo. Material y métodos: Se realizó un estudio cuasiexperimental sin grupo control en el que participaron profesores de cuatro centros concertados de educación infantil, primaria y secundaria, en 3 fases: 1.a de evaluación de conocimientos, 2.a de formación en RCP-B y 3.a de evaluación de las competencias. La formación consistió en una sesión teórica de 40 min y otra práctica de 80 min, con ayuda de maniquís con sistema de retroalimentación de la calidad de las compresiones torácicas. Resultados: Se incluyeron 81 profesores (60,5% mujeres). Tras la formación, el porcentaje de sujetos que realizaron bien la secuencia de RCP-B aumentó de 1,2% a 46% (p < 0,001). La calidad de las compresiones torácicas también mejoró significativamente en cuanto a: posición correcta de las manos (97,6 vs. 72,3%; p < 0,001), profundidad media (48,1 vs. 38,8 mm; p < 0,001), porcentaje que alcanzó la profundidad recomendada (46,5 vs. 21,5%; p < 0,001), porcentaje de descompresiones adecuadas (78,7 vs. 61,2%; p < 0,05), y porcentaje de compresiones realizadas al ritmo recomendado (64,2 vs. 26,9%; p < 0,001). Conclusiones: Tras un programa sencillo y breve, los profesores de colegios concertados son capaces de realizar la secuencia de RCP-B y aplicar las compresiones torácicas con una calidad comparable a la de colectivos con el deber de asistir a una víctima de una parada cardíaca. La comprobación de la capacidad de estos profesionales para hacer una RCP-B de calidad es el primer requisito para que puedan implicarse en la enseñanza de la RCP-B a los escolares. Abstract: Introduction: Teachers may have an essential role in basic life support (BLS) training in schoolchildren. However, few data are available about their BLS learning abilities. Aim: To quantitatively assess the quality of BLS when performed by school teachers after a brief and simple training program. Materials and methods: A quasi-experimental study with no control group, and involving primary and secondary education teachers from four privately managed and public funded schools was conducted in 3 stages: 1 st. A knowledge test, 2 nd: BLS training, and 3 rd: Performance test. Training included a 40 minutes lecture and 80 minutes hands-on session with the help feedback on the quality of the chest compressions. Results: A total of 81 teachers were included, of which 60.5% were women. After training, the percentage of subjects able to perform the BLS sequence rose from 1.2% to 46% (P

Resumen: Introducción: Se ha observado que los profesionales sanitarios tienen dificultades para realizar maniobras de reanimación cardiopulmonar (RCP) de calidad. Nuestro objetivo ha sido comparar la calidad de las ventilaciones en un modelo de lactante según el método utilizado (boca a boca y nariz o bien bolsa autoinflable y mascarilla facial) por estudiantes de Enfermería. Material y métodos: Estudio cuasiexperimental de corte transversal que incluyó a 46 estudiantes de Enfermería de segundo curso. Se realizaron 2 pruebas cuantitativas de RCP pediátrica de 4 min: a) con ventilación boca a boca y nariz; b) con ventilación con bolsa autoinflable y mascarilla facial. Se utilizó un maniquí Resusci Baby QCPR Wireless SkillReporter® de Laerdal. Se registraron y analizaron los porcentajes de ventilaciones con volumen adecuado, excesivo e insuficiente, además de la calidad global de la RCP (ventilaciones y compresiones torácicas). Resultados: Los estudiantes consiguieron dar más ventilaciones con volumen apropiado con el método boca a boca y nariz (55 ± 22%) que con bolsa y mascarilla (28 ± 16%; p

Introduction: It has been observed that health professionals have difficulty performing quality cardiopulmonary resuscitation (CPR). The aim of this study was to compare the quality of ventilations performed by Nursing students on an infant model using different methods (mouth-to-mouth-and-nose or bag-valve-mask). Material and methods: A quasi-experimental cross-sectional study was performed that included 46 second-year Nursing students. Two quantitative 4-min tests of paediatric CPR were performed: (a) mouth-to-mouth-and-nose ventilations, and (b) ventilations with bag-valve-mask. A Resusci Baby QCPR Wireless SkillReporter® mannequin from Laerdal was used. The proportion of ventilations with adequate, excessive, and insufficient volume was recorded and analysed, as well as the overall quality of the CPR (ventilations and chest compressions). Results: The students were able to give a higher number of ventilations with adequate volume using the mouth-to-mouth-and-nose method (55 ± 22%) than with the bag-valve-mask (28 ± 16%, p

IntroductionDecision-making in emergencies is a multifactorial process based on the rescuer, patient, setting and resources. The eye-tracking system is a proven method for assessing decision-making processes that have been used in different fields of science. Our aim was to evaluate the lifeguards' capacity to perform the ABCDE (Airway-Breathing-Circulation-Disability-Exposure) approach when facing a simulated critically ill-drowned victim.MethodsA cross-sectional simulation study was designed to assess the skills and sequence of the ABCDE approach by 20 professional lifeguards. They had to assess a victim and act according to his/her clinical status by following the ABCDE primary assessment approach. The two kinds of variables were recorder: those related to the quality of each step of the ABCDE approach and the visual behaviour using a portable eye-movement system. The eye-tracking system was the Mobile Eye system (Bedford, USA).ResultsNone of the study participants were able to complete correctly the ABCDE approach. Lifeguards spent more time in the Circulation step: Airway (15.5±11.1 s), Breathing (25.1±21.1 s), Circulation (44.6±29.5 s), Disability (38.5±0.7 s). Participants spent more time in viewpoints considered as important (65.5±17.4 s) compared with secondary ones (34.6±17.4 s, p = 0.008). This was also represented in the percentage of visual fixations (fixations in important viewpoints: 63.36±15.06; fixation in secondary viewpoints: 36.64±15.06; p = 0.008).ConclusionProfessional lifeguards failed to fully perform the ABCDE sequence. Evaluation by experts with the help of eye-tracking technology detected the lifeguards' limitations in the assessment and treatment of an eventual critically ill victim. Such deficits should be considered in the design and implementation of lifeguards' training programmes.
