Effect of a new device on improving respiratory function in patients with chronic obstructive pulmonary disease

ABSTRACT

The present study introduced a new device which helped and facilitated breathing exercises in patients [N = 20] with chronic obstructive pulmonary disease. The device consisted of the body of a regular pocket inhaler on the outlet of which a soft balloon was attached. Patients were asked to blow trying to inflate the balloon. Breathing exercises were done 5-10 times each session, four sessions a day, before each meal. Results showed that an improvement in respiratory function [FEV1%] was possible using the new device helped patients; practice through it breathing exercises and ultimately improve their gas exchange, achieve airway clearance and consequently, improve their breathing pattern. This in addition to, improve their exercise tolerance as measured by an improvement in walking tolerance
