INFLUENCE OF DIFFERENT BODY POSITIONS ON PULMONARY FUNCTIONS: A PILOT STUDY

Background: Pulmonary function is one of the most common practice parameters to know airway and lung health. Any abnormality or imbalance can directly change the pulmonary function.Even different body positioning can change pulmonary function. So in different positioning different physiological parameters are having a direct or indirect effect. Objective- The objective of the study was to find out the pulmonary function in supine, sitting and recline positions and compare the pulmonary function of these positions. Procedure- subjects performed PFT 3 times in sitting, recline and supine positions. outcome measures used were FVC,FEV1,FEV1/FVC,FEF25-75% and PEFR. The result showed that sitting position shows better results than supine and recline position. Conclusion- five subjects shows better result in sitting position than supine and recline position.
