Effect of Pursed Lip Breathing Training on Pulmonary Function in Scuba Diving Trainees with Asthma: A pilot Study

Purpose: The current study aimed to determine the safe application of pursed lip breathing (PLB) training in scuba diving trainees with asthma. Methods: Two adults without asthma and two adults with asthma who participated in scuba diving training performed the PLB training for 15 mins 5 times a day for 4 weeks . After the third week of PLB training, the participants joined the scuba diving training. To assess for lung function, forced vital capacity (FVC) was measured before PLB training and before and after scuba diving training. Results: There was no significant change in FVC, forced expiratory volume in 1 second(FEV1), and FEV1/FVC ratio before PLB training and before and after diving training in scuba diving trainees with asthma and those without. Conclusion: Immediate drug treatment is not required, and even individuals with asthma who did not present with severe breathing difficulties can participate in scuba diving training in a diving pool.
