a
Patient ID in table 3 correlates to patient ID in table 2.
b
Value is parentheses represent the % predicted.
c
Significant change was defined as an increase in FEV1 of 12% or in FEF25–75 by 25%
Ŧ
patient was not intubated during ARDS course,
*
Patient has known reactive airway disease
FRC = functional residual capacity, FVC = forced vital capacity, FEV1 = forced expiratory volume(1 sec), FEF25–75 = forced expiratory flowFEF25–75 = forced expiratory flow TLC = total lung capacity, RV/TLC = residual volume as % of TLC, DLCO = diffusion capacity, DLCO/VA = diffusion capacity corrected for alveolar volume, Raw = airway resistance
