Respiratory Minute Volume (RMV) measures the amount of breathing gas a diver inhales and exhales in one minute. This value varies from person to person and plays a crucial role in dive planning. Knowing your RMV helps you estimate the duration of your gas supply at a given depth, promoting safer and more efficient dives.
To calculate your RMV, you need to specify the size of your gas cylinder, the starting and ending pressures, the average depth of your dive, and the duration.
