Back ground: the study is taken up because it is interesting to know about the physiological variations in the position of the diaphragm according to phase of ventilation, body built and position. Clinical importance in the position of the diaphragm related with hemiperisis of diaphragm and emphysema of the lungs. Aims and Objectives: to study the changes in the position of the diaphragm and movements of respiration during phase of ventilation in thin and overweight individuals which includes both males and females. Methods: We have selected 50 individuals in the age group 19-40yrs.All the study groups are taken from Santhiram medical college, particularly students and staff. Two chest x- ray postero-anterior views are taken - after forced inspiration and forced expiration. Results: In thin individuals range of movements of diaphragm varies from 5-6 cms but in over weight individuals it varies from 2.5-4cms. Height of right and left domes of diaphragm in thin individuals are 2.5cms higher when compared to overweight individuals. Elevation of ribs are 0.25cms lesser in thin individuals. Conclusions: All the range of respiratory movements are lower in thin individuals when compared to overweight individuals. It indicates that respiratory excursion is more in overweight individuals. It is interesting to note that in emphysema of lung the height of the diaphragm lies at a lower level.
