Introduction: Over recent years, a growing number of studies have demonstrated the effectiveness of alternative models to centre-based pulmonary rehabilitation (PR) such as tele-PR or home-based unsupervised PR, offering perspectives for improved accessibility and adherence. Other studies have demonstrated the relevance and long-term benefits of maintenance PR programs. However, they remain poorly implemented in real-life settings. In order to encourage patient adherence to new PR models and to guide future orientations, we conducted a survey assessing patients' views on PR models and maintenance programs., Method: The survey (37 questions) was circulated to COPD patients of the French national respiratory patient F.F.A.A.I.R network and in five specialised PR centres., Results: Among the 298 respondents, 75% had previously taken part in a PR program, mainly in hospital settings (91%), with a high degree of satisfaction. The main barriers to PR were being physically separated from their loved ones (21%) and fears of having to share a double room (47%). Regarding maintenance PR programs, patients expressed diversified opinions, in terms of ideal duration and frequency of follow-up, format of follow-up (home-based, telephone, videoconference) and type of professional involved., Conclusions: Diversified PR settings offer perspectives to increase access and improve the effectiveness of current programs. Furthermore, comprehensive personalization (professionals involved, content, setting, duration) seems to be the key to success in concrete implementation and achievement of patient satisfaction., (Copyright © 2024 SPLF.

Introduction: Inspiratory muscle training (IMT) is part of the management of patients with pulmonary diseases during rehabilitation. Since the last recommendations of the Société de pneumologie de langue française, several studies have focused on the role of inspiratory muscle training during pulmonary rehabilitation., Background: IMT, in comparison to standard care or sham-IMT, improves the strength and endurance of the inspiratory muscles, decreases dyspnoea during the activities of daily living, improves walking distance and quality of life. However, the different studies did not show an additional effect of IMT during a pulmonary rehabilitation program compared to a rehabilitation program without IMT, with regard to improvement of exercise capacity and quality of life., Outlook: One study showed an improvement in dyspnoea of effort, but these results are yet to be confirmed. Finally, it seems appropriate to associate IMT with an exercise-training program before chest or abdominal surgery, even if further studies are necessary., Conclusion: During a pulmonary rehabilitation program, IMT does not provide additional benefits. However, when patients cannot perform a global exercise training, IMT has shown benefit. IMT provides additional benefits in pre-operative programs., (Copyright © 2021 SPLF.

Chronic respiratory disease is a major cause of morbidity and mortality worldwide and an important cause of disability including a reduction of exercise, functional and muscle capacity contributing to a decreased quality of life. In the context of pulmonary rehabilitation, a thorough patient-centered outcome assessment, including not only measures of lung function, but also exercise functional and muscle capacity, is imperative for a comprehensive disease management. Assessment of these impairments and dysfunctions with appropriate and change-sensitive procedures is thus necessary for personalizing the physical interventions and assessing the short- and long-term effectiveness of the intervention. The clinician currently has a wide variety of tests and measurements available to assess the physical and functional capacity of people with chronic respiratory disease. The aim of this review is to provide a pragmatic synthesis of the physical, functional and muscle capacity tests most commonly used in pulmonary rehabilitation. Ultimately, it should help the clinician to identify the relevant evaluations according to the objectives of the patients but also according to the available resources, the setting of pulmonary rehabilitation and the specific qualities of each test., (Copyright © 2021 SPLF.

Background: Many types of interfaces with intentional leaks exist for Non Invasive Ventilation. The purpose of intentional leaks is to remove CO2 from the interface, however the calibration does not allow a sufficiently large flow and rebreathing of CO2 can occur. The aim of this study was to compare the CO2 rinsing capacities of three new generation oronasal masks with intentional leaks (A: Quattro®, [Resmed]; B: Amara® [Respironics]; C: Forma® [Fisher&Paykel]) in healthy subjects., Methods: Seventeen healthy volunteers were included in this prospective cross-sectional, randomized, double-blinded trial. Each subject underwent ventilation with a home ventilator (IPAP: 14 cmH2O; EPAP: 4 cmH2O) with each mask consecutively. Transcutaneous capnography (PtcCO2) recordings were carried out throughout the trial and ventilator data (tidal volume, respiratory rate, minute ventilation and unintentional leaks) were also analyzed. Mask comfort was assessed using a visual analog scale (0 to 10)., Results: The results showed no differences in PtcCO2 between masks (P=0.82). There were no significant differences in respiratory parameters (tidal volume, P=0.79; respiratory rate, P=0.65; minute ventilation, P=0.12) between masks. The rate of unintentional leaks were significantly lower for Mask A (P=0.016). Subjects rated Mask A and Mask C as more comfortable than Mask B (P=0.041)., Conclusion: There was no effect of mask on PtcCO2 in healthy subjects. The mask with the highest comfort rating had not the lowest rate of unintentional leaks.

Patients suffering from Chronic Obstructive Pulmonary Disease (COPD) are usually evaluated for cardio-respiratory capacity on a flat surface even though these patients generally encounter discomfort only when climbing stairs or ascending a slope. The purpose of this study was to describe the cardio-respiratory evaluation of these patients on climbing stairs. A staircase test was carried out and compared to the 6-min walking test. The maximum duration of ascent was 2 min, covering a maximum of four flights of stairs. The conditions of the staircase test and the instructions given to the patients regarding walking were designed to be consistent with the activities of daily life. We recorded the height reached and the distance covered; we also recorded dyspnoea, oxygen saturation (SpO2) and heart rate (HR); we estimated the maximal oxygen consumption (VO2max) and the physiological cost index (PCI) during each test. The statistical analysis of the results was surprising: it showed that there was no significant difference between the 6-min walking test and the stair climbing test on the following criteria: estimated VO2max, SpO2, and variation in heart rate between rest and effort (DeltaHR); it also showed that these two tests correlated well for dyspnoea (p<0.0001). It appears that the PCI of stair climbing is much higher than the PCI of walking on a level surface. These results may be explained partly by the anaerobic metabolic pathway used predominantly by patients with COPD in brief periods of exertion and partly by the muscular dysfunction which also accompanies brief exertion. The use of the PCI adds greater precision to the interpretation of the results of cardio-respiratory evaluation of COPD patients. The value of this index is proportional to the incapacity described by these patients. The staircase test is complementary to the 6-min walking test, making it possible to evaluate restriction of activity in COPD patients. Its implementation is simple and accessible.
