Aim: This initial Norwegian study aimed to quantify the vibrations and sounds experienced by neonates when they were transported by helicopter in an incubator., Methods: Two neonatal manikins weighing 500 and 2000 g were placed in a transport incubator and transported in an Airbus H145 D3 helicopter during standard flight profiles. The vibrations were measured on the mattress inside the incubator and the sound levels were measured inside and outside the incubator., Results: The highest vibration levels were recorded during standard flight profiles when the lighter manikin was used. These ranged 0.27-0.94 m/s 2 , compared to 0.27-0.76 m/s 2 for the heavier manikin. The measurements exceeded the action levels set by the European Union Vibration Directive for adult work environments. The sound levels inside the incubator ranged 84.6-86.3 A-weighted decibels, with a C-weighted peak level of 122 decibels. The sound levels inside the incubator were approximately 10 decibels lower than outside, but amplification was observed in the incubator at frequencies below 160 Hz., Conclusion: Vibrations were highest for the lighter manikin. The sound levels during helicopter transport were higher than recommended for neonatal environments and sounds were amplified within the incubator at lower frequencies., (© 2024 The Author(s).

Objective: Norwegian critical care resources are regionalized making air ambulances transport of suspected or confirmed coronavirus disease 2019 (COVID-19)-positive patients a necessity. We prospectively observed pre- and interhospital transportation of patients with suspected or confirmed COVID-19 in our physician-manned emergency medical services., Methods: This was a prospective, observational quality assurance study of primary and secondary missions conducted by 2 Norwegian air ambulances during the COVID-19 pandemic., Results: Forty-one (24.1%) were primary missions, whereas 129 (75.9%) were interhospital transports. Most patients (158 [92.9%]) were transported with ground-based vehicles, and 12 (7.1%) were transported by rotor wing aircrafts. One hundred thirty-four of 170 patients (78.8%) were COVID-19 positive at the time of transportation. The median (interquartile range) fraction of inspired oxygen concentration was 0.60 (0.50-0.80), the positive end-expiratory pressure was 11 cm H 2 O (8-13.5 cm H 2 O), and the peak inspiratory pressure was 26 cm H 2 O (22-30 cm H 2 O). Some degree of elevated treatment challenge was reported in 157 (87.7%) transports, and in 139 (77.7%), the patient risk was considered elevated. The physician stated that some degree of elevated risk for the provider was elevated in 131 (73.2%) of the transports., Conclusion: The capacity of the physician-manned emergency medical services to safely transfer patients remains essential to maintain resilient critical care capacity, and the perceived elevated risks should be considered in capacity planning., (Copyright © 2023 The Authors.

Background: Continuous medical education is essential in Helicopter Emergency Medical Services (HEMS). In-situ simulation training makes it possible to train in a familiar environment. The use of a dedicated facilitator is essential; however, when an in-situ simulation training session is interrupted by a live mission, the efforts invested in the training are left unfulfilled. This study aims to evaluate if HEMS mission observation and debriefing by the simulation facilitator is a feasible alternative to mission-interrupted simulation training, and how this alternative to simulation training is perceived by both facilitators and HEMS crew members., Methods: Facilitator observation during live missions and post-mission debriefing was offered as an alternative to mission-interrupted simulation training over a one-year period at three HEMS bases. Immediate feedback was requested from crews and facilitators after each observed live mission on a predefined questionnaire. At the end of the study period, semi-structured interviews were performed with a sample of HEMS crew members and facilitators to further explore the experience with the concept. Numerical data about the sessions were recorded continuously., Results: A total of 78 training sessions were attempted, with 46 (59%) of the simulations conducted as planned. Of the remaining, 23 (29%) were not started because the crew had other duties (fatigued crew or crew called for a mission where observation was inappropriate/impossible), and 9 (12%) training sessions were converted to observed live missions. In total, 43 (55%), 16 (21%) and 19 (24%) attempts to facilitate simulation training were undertaken on the three bases, respectively. The facilitators considered mission observation more challenging than simulation. The interviews identified local know-how, clinical skills, and excellent communication skills as important prerequisites for the facilitators to conduct live mission observation successfully. Participating crews and facilitators found simulation both valuable and needed. Being observed was initially perceived as unpleasant but later regarded as a helpful way of learning., Conclusion: Live mission observation and debriefing seems a feasible and well-received alternative to an in-situ simulation program in HEMS to maximise invested resources and maintain the learning outcome. Furthermore, additional training of simulation facilitators to handle the context of live mission observation may further improve the learning output., (© 2021. The Author(s).)
