Abstract- Introduction- Pursed lip breathing (PBL) is spontaneously adopted by COPD patients to relieve dyspnea. A systematic review done by S. E. Roberts et al concluded that studies should be done to find the short-term benefits of PBL that helps in clinical improvement in patient’s status. So with this background the study was undertaken to find the effect of PLB in stable COPD patients for shorter time on saturation levels, dyspnea and PEFR Readings. Methodology- IEC approval from institute and written informed consent was signed by the subjects. This is an Experimental study and included 56 stable COPD patients were included in the study with inclusive criteria of Diagnosed case of Stable COPD Patients on regular medication and visiting respiratory OPD and IPD of tertiary care center. Exclusive criteria was Patients of acute exacerbation, Smokers, Patients on O2 therapy, Patients not willing to participate. Baseline parameters were recorded and then PLB was taught and performed for 6 days then on 6th day post intervention reading were taken and parameters were compared to baseline. Results- Short term effect of pursed lip breathing in COPD was analyzed. Mean age of the patients was 60.83± 7.43 years. The study population comprised of 37 (66.07%) male patients and 19(33.93%) female patients. Short term effect pursed lip breathing statistically significantly improves saturation, dyspnea and PEFR in stable COPD patients. Conclusion- Short term effect pursed lip breathing improves saturation, dyspnea and PEFR in stable COPD patients.
