Data presented as mean ± standard deviation. PTEF, peak tidal expiratory flow; V_T, tidal volume per kilogram of body weight; t_PTEF/t_E, ratio of time to peak expiratory flow to total expiratory time; V_PTEF/V_E, ratio of exhaled volume to peak expiratory flow to tidal volume; TEF10, TEF25, and TEF50, tidal expiratory flow rates at 10%, 25%, and 50% of the remaining tidal volume; 25/PT, ratio of TEF25 to the PTEF. ^*P < 0.05 between pre and post values.
