An Analytical Study on Variation in Diaphragm Position and Shape (Costo - Phrenic Angle) in COPD Patients

Abstract

Background: Increased airflow resistance, hyperinflation, air trapping are the main pathophysiologic features of COPD. A more rigorous of the normal variation in diaphragm position and shape, based on easily recognised anatomic landmarks, and analysis of factors that might contribute to this variation, such as age and weight, may provide a more reliable basis for this assessment. Purpose of the study: To find out the variation in diaphragm position and shape (costo-phernic angle) in COPD patients. Method: 30 COPD subjects were selected randomly from Dhiraj general hospital, Vadodara, Gujarat with 30 counterpart normal subjects with same age group and both sex. Their PA chest radiographs had been taken for the measurement of costo - phernic angle and it was measured. Costo - phernic angle of COPD subjects was compared with normal subjects. Results: p values were get through analysis of data by using independent sample 't'test with spss version 11.0. the values were p<0.000 for right side and p<0.258 for left side when costo - phernic angle of COPD was compared with normal subjects. Conclusion: There were variation in position and shape of diaphragm in COPD subjects to normal subjects by means of high level significance in same age group.
