Breathing Exercise Application for Enhancing Lung Function Performance in Chronic Obstructive Pulmonary Disease

Abstract

This research presented the mobile application for respiratory training to enhance pulmonary efficiency in patients with Chronic Obstructive Pulmonary Disease (COPD) on the Android operating system. The aim is to facilitate the revitalization of lung function and reduce breathlessness. Given the current prevalence of various respiratory conditions, it is noteworthy that COPD is more severe than other respiratory disorders. This underscores the growing awareness of the importance of popular lung health care, specifically through breathing exercises such as Pursed Lip Breathing. Based on experimental studies conducted by Shafiq and colleagues on COPD patients, Pursed Lip Breathing has been identified as effective in restoring pulmonary capacity compared to pre-training conditions. Furthermore, some patients may need to invest in breathing training devices, which could be expensive. The application simulates breathing exercises, allowing users to practice, record their training history, and assess the severity of COPD before and after training. The Forced Expiratory Volume in one second (FEV1) is measured using a spirometer to evaluate the severity of airway obstruction. Users can track the severity of airway obstruction and record their assessment history. In a 7-day trial of Pursed Lip Breathing exercises with application users, there was a significant alleviation of breathlessness and improvement in pulmonary function. The overall user satisfaction level was found to be 3.73, indicating a high level of satisfaction.
