Detailed explanation-1: -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-2: -Total Lung Capacity The vital capacity (VC) is the maximal volume of gas exhaled during a forced exhalation after a forced inhalation. Thus VC is the sum of the VT, IRV, and ERV. The VC is approximately 4.5 L in a healthy 70-kg adult.
Detailed explanation-3: -The vital capacity (VC) is the maximum volume exhaled after maximum inhalation (IRV + TV + ERV). The total lung capacity (TLC), about 6 L, is the maximum amount of air that can fill the lungs (IRV + TV + ERV + RV).
Detailed explanation-4: -It is determined after a key measurement of lung volume-functional reserve capacity (FRC)-has been measured. FRC refers to the volume of air left in the lungs after a normal, passive exhalation and used to evaluate the elasticity of the lungs and chest wall.
