Detailed explanation-1: -Residual volume can be understood by investigation of breathing that exceeds tidal volumes. Following maximal inspiration, the volume of air that leaves the lungs during a maximal force expiration is known as the vital capacity (VC).
Detailed explanation-2: -Residual Volume(RV) It is the volume of air remaining in the lungs after maximal exhalation. Normal adult value is averaged at 1200ml(20‐25 ml/kg) .It is indirectly measured from summation of FRC and ERV and cannot be measured by spirometry.
Detailed explanation-3: -Residual volume is the amount of air that remains in a person’s lungs after exhaling fully. During the breathing cycle, when air is taken in and let out, the lungs always contain a residual volume of air to ensure that there is sufficient time for oxygen to be absorbed and for the carbon dioxide to be released.
