A Randomized Control Study to Find the Efficacy of Pursed Lip Breathing In Lung Volumes and Capacities of Patients with Chronic Obstructive Pulmonary Disease (COPD)
Journal Title: Journal of Medical Science And clinical Research - Year 2014, Vol 2, Issue 10
Abstract
Objective- Efficacy of pursed lip breathing with medical management compared to only pursed lip breathing in lung volumes and capacities of patients with COPD. Study Design- Pre and post experimental study design Setting- The study was conducted in Pulmonary Rehabilitation unit of Navodaya Medical College Hospital and Research Center, Raichur. Participants- 30 patients who were suffering from mild to moderate symptoms of COPD were randomized into two groups by using simple random technique. They were experimental and control groups respectively. Interventions-30 subjects who were diagnosed with stable COPD were randomly allocated into experimental and control groups. Both the groups received medication of oral Theophylline + MID of Salbutamol and Ipratropium Bromide. However, experimental group received an additional intervention of pursed lip breathing. Outcome Measures-Spirowin Computerised Spirometry Results-There was a statistically significant improvement within the group for both the groups in all the parameters of lung volumes and capacities when compared pre and post test values. Whereas, there was highly significant post test difference in Tidal volume(P<0.02) and Maximum Voluntary Ventilation(P<0.001) in the experimental group when compared with the post test values of control group suggestive of the effect in the parameters of TV and MVV, which are an integral part of improvement of patients symptoms in COPD. But there was no significant difference in FEV1, FVC, FEV1/FVC ratio between the experimental and control groups after the treatment (P>0.05). Conclusion- Present study concludes that there was no significant difference in pre test of treatment in both experimental and control groups. Significant improvement in TV and MVV in the experimental group and no significance difference was found in FEV1, FVC and FEV1/FVC ratio in control group in post test of treatment.
