Calculating SAC and RMV

  • Surface Air Consumption (SAC): The amount of gas you breathe in one minute at the surface in terms of pressure (psi). SAC can be expressed as pressure (psi) or volume (cu ft).
  • Respiratory Minute Volume (RMV): The amount of gas you breathe in one minute at the surface in terms of volume (cu ft).
  • Resting SAC: The rate at which you breathe when relaxed.
  • Working SAC: The rate at which you breathe when stressed.
