A STUDY TO IDENTIFY THE CHEST EXPANSION VALUES AND PEFR VALUES AMONG CONSTRUCTION WORKERS

Abstract

Chest expansion measurements were used to evaluate a patient’s baseline status, treatment effectiveness, and progression of disease with regards to chest wall mobility and respiratory muscle function.   Peak expiratory flow rate (PEFR) is the maximum flow rate generated during a forceful exhalation, starting from full lung inflation with the help of peak expiratory flow meter. Chest expansion was measured at two levels i.e. axillary and xiphoid process and the mean values of the two levels were recorded. This was followed by measuring Peak expiratory flow rate (PEFR) where the subject is asked to deeply inspire and exhale through the Peak expiratory flow meter. The purpose of the study is to find out the chest expansion and PEFR values among construction workers.
