Residual 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.
Residual volume from a gastrostomy tube (G-tube) should be checked before feeding to ensure it is less than a specified amount (usually 100-200 mL) as a large residual volume may indicate feeding intolerance or gastric retention. If the residual volume exceeds the defined threshold, it is important to follow the healthcare provider's instructions on how to proceed with feeding.
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.

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
Functional Residual Capacity (FRC) = Expiratory Reserve Volume (ERV) + Residual Volume (RV)
Residual volume allows gas exchange to go on continuously
