The effect of incentive spirometry on chest expansion and breathing work in patients with chronic obstructive airway diseases: comparison of two methods.
BACKGROUND Chronic obstructive airway diseases ( COAD ) , characterized by mucus hypersecretion , lead to exercise intolerance . Incentive spirometry has been used to prevent postoperative pulmonary atelectasis . METHODS To compare the efficacy of two incentive spirometers , Coach ( volume-oriented ) and Triflo ( flow-oriented ) , in the work of breathing in COAD patients , 22 patients were r and omized in this study : 12 patients ( Triflo-II group ) initially used Triflo-II for 10 minutes and then Coach for the same period . In contrast , the Coach group , including 10 patients , started with Coach followed by Triflo-II . After receiving incentive spirometry , lung expansion and work of breathing were assessed . RESULTS Patients in the Coach group significantly increased chest wall expansion ( p = 0.041 ) , as compared with patients using Triflo-II . Similarly , there was also a significantly increased abdominal wall expansion in the Coach group ( p = 0.0056 ) , compared with that in the Triflo-II group . The need of accessory muscle assistance for breathing in the Coach group was significantly less than in the Triflo-II group ( p = 0.047 ) . It was easier for patients in the Coach group to start a breath ( p = 0.0058 ) than for those in the Triflo-II group . For the entire group , 17 patients ( 77.3 % ) preferred Coach to assist their breathing , and only 4 patients ( 18.2 % ) favored Triflo-II . CONCLUSION COAD patients achieved a larger expansion of the chest and abdomen with a Coach device . Our data provide a good rationale for an outcome study on the use of incentive spirometer in COAD patients
