Purpose : To compare the immediate effects of air stacking maneuver using resuscitator bags and balloons
Methods : Twenty healthy young adults participated in this study. Forced vital capacity (FVC) and peak cough flow (PCF) tests were performed at pre-intervention, and then, the maximum insufflation capacity (MIC), forced expiratory volume in 1 s (FEV1), FEV1/FVC, peak expiratory flow (PEF), and peak cough flow (PCF) were measured using the air stacking maneuver via resuscitator bags and balloons. Interventions were randomly performed, and a 40-min break was provided between interventions. The evaluation process in this study was conducted in accordance with the guidelines of the American Thoracic Society (ATS) 2019. To compare the three outcomes measured at pre-and post-interventions, repeated measures analysis of variance was performed.
Results : A significant difference was found in the MIC, FEV1, PEF, and PCF after the air stacking maneuver using resuscitator bags and balloons, whereas no significant difference was observed between resuscitator bags and balloons
Conclusion : No significant difference was found in the immediate effect of the air stacking maneuver using resuscitator bags and balloons in this study. Air stacking maneuver using balloons can increase the success rate of the techniques by providing visual feedback on the amount of air insufflation when performed with balloon blowing exercise. Balloons are cheaper and easier to buy compared to manual resuscitator bags; therefore, education on the air stacking maneuver using balloons will have a positive effect on pulmonary rehabilitation.
