Respiratory Minute Volume (RMV)

Respiratory minute volume (RMV), also referred to as the Surface Air Consumption (SAC) rate or Surface Consumption Rate (SRC). RMV represents the volume of breathing gas that enters and exits a person's lungs, on average, within a minute. This metric varies from individual to individual. Understanding one's RMV is essential in advanced dive planning as it facilitates the estimation of the duration a specific gas supply will last at a specified depth.
