Brief Summary: Show A randomized control trial was conducted at physiotherapy department of Pakistan Railway General Hospital from July 2017 to Dec 2017. 30 patients with stable COPD were enrolled in the study on the basis of inclusion and exclusion criteria. The participants were randomly assigned into two groups, Group A= interventional group, Group B = control group through toss and coin method using non-probability convenient sampling technique and written consent was obtained from each patient participated in the study. From 30 patients 15 patients were randomly allocated to each group, Group A: Interventional (n= 15), Group B: Control (n=15). 1 patient in control group B was dropout because he didn't come for follow up. Overall 29 patients were evaluated for study as in Group A, interventional (n=15) and Group B control (n=14).Patients in group A were performed breathing control at the start of session and then Purse lips breathing technique during aerobic bicycling for 8 min while in group B patients first perform breathing control and then aerobic bicycling for 8 min. Subjects in both experimental and control group underwent spirometry and baseline vitals, such as Respiratory rate, blood pressure, and oxygen saturation, at rest and at the completion of session was noted. Borg scale of dyspnea also used to rate the level of dyspnea at rest and at the end of session. Clinical COPD Questionnaire (CCQ) was used at 1st and final week of evaluation. It was 6 weeks training protocol, with three days per week session was given to the patient.

What is the effect of pursed lip breathing?Through purse-lip breathing, people can have relief of shortness of breath, decrease the work of breathing, and improve gas exchange. They also regain a sense of control over their breathing while simultaneously increasing their relaxation.
Why do people do pursed lip breathing?Pursed lip breathing is one of the simplest ways to control shortness of breath. It provides a quick and easy way to slow your pace of breathing, making each breath more effective.
How does pursed lip breathing prevent alveoli?Pursed-lip breathing is believed to increase positive pressure generated within the airways and to buttress or stent the small bronchioles, thereby preventing premature airway collapse.
