Effect of Different Angle on Pulmonary Function in Young Healthy Females

Abstract

Background: Pulmonary function tests play an important role in the assessment, diagnosis, quantification of the ventilatory disorders intensity, and treatment course. Changes in posture can affect the resting length of respiratory muscles and the vestibular system contributes to altering respiratory muscle activity during movement and changes in posture. Aim of this study is to find different angle changes how effect on the pulmonary function. Results: The result shows significant difference of FVC and FEV1 values in supine, oblique and head down positions [P value=0.000]. The values of FVC and FEV1 are highest in oblique position. Conclusion:There was significant difference in effect of different angle on pulmonary function and it was highest in oblique (45 0 ) position.
