WebFeb 28, 2011 · The lung response to acute altitude exposure is mainly hyperventilation which, together with elevated heart rate, aims at achieving an adequate supply of oxygen to the tissues. At rest, ventilation increases by firstly increasing the tidal volume, at least up to 3500 m. Above this altitude, also the breathing rate significantly increases.

WebThe reserve volume is the amount of air that remains in the lungs and passageways after a maximal expiration. Vital capacity is the total of the tidal volume, inspiratory reserve volume, and expiratory reserve volume. In a normal healthy adult lung, the vital capacity usually ranges from 3.5 to 5.5 L of air.
