Dependant on the patient really, but it should be around 150-200 mL if I'm not mistaken.

∙ 11y agoResidual volume of air is the volume of air remaining in the lungs after maximal exhalation. It is not possible to voluntarily exhale this air, as it helps to keep the lungs inflated and prevents them from collapsing. Residual volume plays a key role in maintaining the oxygen-carbon dioxide exchange in the lungs.
The air that can not be exhaled is called residual volume.TV = the amount of air displaced during normal breathing.IRV = The amount of air that can be taken in forcibly beyond tidal volumeErv= The amount of that can be expelled forcibly.Vital capacity = the total amount of exchangeable air.Total Lung capacity = TV + IRV + ERV + RESIDUAL VOLUME
Tidal volume is the volume of air that moves in and goes out in asingle stroke, and is abut 500ml.
residual volume
this is called residual volume.
The residual volume is the volume of air remaining in the lungs after the most powerful expiration.
Residual volume is the air that remains in the lungs after a maximal exhalation. It is considered a type of "stale" or stagnant air that cannot be voluntarily expelled and helps keep the lungs inflated.
residual volume
residual volume
Functional Residual Capacity (FRC) = Expiratory Reserve Volume (ERV) + Residual Volume (RV)
Residual volume allows gas exchange to go on continuously
The function of residual volume is to keep enough pressure in the lungs to keep them from collapsing.
