Detailed explanation-1: -To sum up: Your expiratory reserve volume is the amount of extra air-above anormal breath-exhaled during a forceful breath out. The average ERV volume is about 1100 mL in males and 800 mL in females.
Detailed explanation-2: -Expiratory reserve volume is the maximal volume of air that can be exhaled from the end-expiratory position. This is the difference between the volume of air left in the lung at the conclusion of normal expiration versus at the conclusion of maximal expiration. Expiratory reserve volume is about 1.1 litres or 1100 ml.
Detailed explanation-3: -Following maximal inspiration, the volume of air that leaves the lungs during a maximal force expiration is known as the vital capacity (VC). VC is composed of the tidal volume, expiratory reserve volume (ERV), and inspiratory reserve volume (IRV).
Detailed explanation-4: -Expiratory reserve volume (ERV) is the amount of air that can be forcibly exhaled beyond a tidal exhalation (about 1200 ml for men & 700 ml for women).
