Abstract (2. Language): 
Background: This study aimed to distinguish which position generates higher peak expiratory pressure. And provide framework for clinical decision making in the management of patient with COPD with special emphasis on body positions. Study was performed with two groups that is group I & II. (COPD & non COPD subjects) selected for the study. PEFR measured with explanation in eight different positions ( Standing, Forward bend sitting, Chair sitting, Recline sitting, Supine lying, Side lying (right), Side lying (left), Head down.) In each position three reading taken out of three best one was taken for the study. Results: In normal subject standing PEFR ( 437 ± 16 L / min ) and head down PEFR ( 371 ± 15 L /min) were significantly reduced than all other positions. In COPDs standing PEFR (189 ± 8 L / min ) & head down PEFR ( 130± 6L /min) were significantly reduced than all other positions. Body position has significant effect on peak expiratory flow rate in patients with chronic obstructive pulmonary disease and normal subjects. Generally, the more upright position, the higher peak expiratory flow rate .There was strong correlation between PEFR & body position. Conclusion: Patients should encourage adapt more upright position to maximize the strength of coughing & huffing.
