Document Summary

Low & moderate exercise: vt tidal volume how much gas you inhale in one breath, frc functional residual capacity after normal expiration. Acute pulmonary adaptation to exercise: lecture 8: rv residual volume - gas always left in lungs maintains gas exchange & prevent lung, erv expiratory reserve volume collapse. Vemax & mvv: vemax = ve at maximal exercise (highest ventilation at maximal exercise, lower in females, lower in copd patients due to airway obstruction, high in rugby players, mvv = maximal voluntary ventilation. Or maximal breathing capacity: copd patients have small breathing reserve (14l/min-17l/min) due to airflow limitation they use up almost all of their breathing capacity. Mvv - max voluntary ventilation or max breathing capacity (fev1 x 35 or 40: therefore, breathing reserve differs. 80-120 l. min-1 between groups (e. g. athletes, copd, gender: at maximum exercise, the highest ve (e. g. 60) is smaller than the mvv (e. g. 80) as there is always a reserve volume in the lungs (cid:523)(cid:498)breathing reserve(cid:499)(cid:524)
