differentiate between tidal volume and residual volume
Hello,
Tidal volume is the volume of air inspired in a single, normal breath. Inspiratory capacity is the amount of air taken in during a deep breath, while residual volume is the amount of air left in the lungs after vigorous or powerful respiration.
Tidal volume is the volume of each breath as measured during inspiration or expiration or averaged for the entire respiratory cycle
Thank you.
Dear aspirant hope you are doing well..
Tidal Volume (TV) is the normal volume of air that can be inhaled or exhaled during one respiratory cycle. It considers the functions of the respiratory centres, respiratory muscles, the mechanics of the lung and chest wall. Approximately it measures around 500 ml of air in a healthy adult man.
2) Inspiratory Reserve Volume (IRV) is the amount of air that can be forcibly inhaled after a normal respiratory cycle. IRV is reserve volume, so used during deep breathing. It values about 1900-3300ml.
3) Expiratory Reserve Volume (ERV) is the volume of air that can be exhaled forcibly. Its range value is 700-1200ml.
4) Residual Volume (RV) is the volume of air remaining in the lungs after forcible exhalation. Its value is about 1200ml.
Hope it's helpful..
Thank you
