It is the measurement used for gut motility. It is checked every 4 to 6 hours in enteral nutrition patients. If the RV is between 200 and 500 ml, measures are taken to prevent aspiration.
The function of residual volume is to keep enough pressure in the lungs to keep them from collapsing.
Residual risk is determined after you reassess the hazards as if the controls were in place.

Dependant on the patient really, but it should be around 150-200 mL if I'm not mistaken.
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.
residual volume
Functional Residual Capacity (FRC) = Expiratory Reserve Volume (ERV) + Residual Volume (RV)
Functional residual capacity (FRC) is the volume of air remaining in the lungs after a normal exhalation, while residual volume (RV) is the volume of air remaining in the lungs after a maximal exhalation. FRC includes both the expiratory reserve volume and the residual volume, while RV is the volume of air that cannot be exhaled from the lungs.
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.
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 (reserve) volume
The volume not included in the vital capacity is the residual volume (RV). Residual volume is the amount of air that remains in the lungs after a maximal exhalation and cannot be voluntarily expelled. Vital capacity, which consists of tidal volume, inspiratory reserve volume, and expiratory reserve volume, measures the maximum amount of air a person can exhale after a deep breath, excluding the residual volume.
To accurately measure residual volume in a container, you can use a graduated cylinder or a measuring cup with clear markings. Fill the container with the substance, making sure it is level with the top. Then, carefully pour the substance into the measuring tool and note the volume. Subtract this volume from the total volume of the container to determine the residual volume.
