Pulmonary volumes Tidal volume(潮气量) Volume of air inspired or expired during a offal inspiration or expiration(400-500 ml) Inspiratory reserve volume(补吸气量) Amount of air inspired forcefully after inspiration of normal tidal volume(1500-2000 ml Expiratory reserve volume(补呼气量) Amount of air forcefully expired after expiration of normal tidal volume(900-1200 mD Residual volume(残气量,RV) Volume of air remaining in respiratory passages and lungs after the most forceful expiration(1500 ml in male and 1000 ml in female)
5 Pulmonary Volumes • Tidal volume (潮气量） – Volume of air inspired or expired during a normal inspiration or expiration (400 – 500 ml) • Inspiratory reserve volume （补吸气量） – Amount of air inspired forcefully after inspiration of normal tidal volume (1500 – 2000 ml) • Expiratory reserve volume （补呼气量） – Amount of air forcefully expired after expiration of normal tidal volume (900 – 1200 ml) • Residual volume （残气量，RV） – Volume of air remaining in respiratory passages and lungs after the most forceful expiration (1500 ml in male and 1000 ml in female)
