Gas Consumption

All divers, whether recreational or technical divers, should know how much gas they need for diving.  The starting point for this is for a diver to calculate their breathing rate, known as Surface Air Consumption (SAC) or Respiratory Minute Volume (RMV).  Departure has a program that will do this.  All that is needed is the average depth (which many computers or data loggers will give) of a dive (or a segment with a constant depth for a specified time)  Information is then entered into the RMV/SAC program and the diver's breathing rate is calculated.
