Cardiac Bypass Mode (CBM)

CBM mode allows patient monitoring without unnecessary alarms during extracorporeal oxygen enrichment of the patient by a heart-lung machine.

Properties of CBM mode:

  • All gas concentrations are measured independent of the respiratory phase.
  • The CO2 apnea and pressure apnea alarms are inactive.

The CBM mode can be used in all active ventilation modes. When ventilation modes are changed, the CBM mode remains active. Changing to the Standby mode deactivates the CBM mode.
