SESSION TITLE: Airways 1
SESSION TYPE: Original Investigation Poster
PRESENTED ON: Wednesday, October 26, 2016 at 01:30 PM - 02:30 PM
PURPOSE: To explore various pulmonary function parameters that can help to differentiate AIR from COPD patients with similar degree of obstruction.
METHODS: Total 101 patients, 51 Asthma (35 Males & 16 Females) and 50 COPD (48 Males & 2 Females) already on treatment, subjected to extensive lung function tests including pre and post bronchodilator spirometry, Body plethysmography and Diffusion capacity with carbon monoxide(DLCO).They were stratified into 4 groups according to severity of obstruction (FEV1%) ie. ≥ 80%, 51-79%, 31-50% and ≤ 30%.Both the groups were compared for FRC% (Functional Residual Capacity), TLC% (Total Lung Capacity), RV% (Residual Volume), RV/TLC%, Raw (airway resistance), sGaw (specific airway conductance) with postbronchodilator reversibility and DLCO% using independent t-test. Correlation of FEV1% with other parameters was done using Pearson analysis.
