Allowed range: 170 to 300 bar.
Allowed range: 5 to 20 L.
RMV (Respiratory Minute Volume) converts your SAC rate from pressure per minute to volume per minute, making it tank-independent and ideal for gas planning across different tank configurations.
RMV Formula:
• SAC Rate
Measured in pressure per minute (PSI/min or bar/min). Tank-dependent — changes with different tank sizes.
• RMV
Measured in volume per minute (L/min or cuft/min). Tank-independent — stays the same regardless of tank used.
• When to use RMV
Use RMV when planning dives with different tanks, comparing consumption between divers, or calculating gas requirements for a dive plan.
