Values are mean±standard deviation. COPD = chronic obstructive pulmonary disease, n = number, FEV1 = forced expiratory volume for 1 second, FVC = forced vital capacity, RV = residual volume, DLCO = diffusing capacity of lung, carbon monoxide, PaO2 = partial pressure, arterial oxygen, PTSD = post traumatic stress disorder.
