Detailed explanation-1: -The volume of air which remains in the lungs even after forceful expiration is Residual volume. Its about 1100 ml to 1200 ml.
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.
