Background: Lung volume recruitment (LVR) is a stacked-breath assisted inflation technique in which consecutive insufflations are delivered, without exhaling in between, until the maximum tolerable inflation capacity is reached. Although LVR is recommended in some neuromuscular disease guidelines, there is little information detailing when and how allied health professionals (AHPs) prescribe LVR. Objective: This study is aimed at describing the use of LVR in practice across Brazil. Methods: A cross-sectional e-survey (Sep-Nov 2023) explored LVR practices among qualified clinical or home care AHPs in Brazil. It gathered participant data on geographical region, profession, and experience. It delved into LVR specifics: clinical population and indications for use, prescription (frequency, dosage, and interfaces), related side effects, outcomes assessed, and combined therapies. Results were presented descriptively. Results: One hundred two surveys (74 physical therapists (PTs) and 28 speech and language pathologists (SLPs)) from diverse locations were collected. LVR was predominantly prescribed for adults (57%), with the most common diagnosis being amyotrophic lateral sclerosis (84%). Changes in peak cough flow and vital capacity were the most common reasons for LVR prescription. Maximal insufflation capacity was reportedly measured by 58% of PTs and 22% of SLPs. Chest wall soreness and discomfort were the most common side effects, and many respondents did not provide warnings about potential side effects (42% PTs and 50% SLPs). The study highlighted common use of other respiratory therapy devices alongside LVR. Conclusion: LVR is available in routine clinical and home care settings in Brazil. There is a lack of standardization regarding indications, prescription, and outcome measures among PTs and SLPs in Brazil. Clear recommendations and guidelines are needed to standardize these parameters, enabling more objective data and facilitating comparisons between centers. |
