O2 supply pressure alarm

O2 supply pressure alarm
Manifestations
  • Alarm message for O2 supply pressure low
  • Loss of O2 and nitrous oxide flow
  • Loss of air flow on some anesthesia workstations (with failsafe valve on the air piping)
  • Loss of auxiliary O2 flow
  • Loss of ventilator cycling (with pneumatically powered ventilator)
Potential causes
  • Patient factors (none)
  • Equipment factors
    • Loss of pipeline O2 supply
      • Facility-wide
      • At zone valve
      • O2 pipeline hose disconnected
    • Empty backup O2 cylinder
Suggested responses
  • Open backup O2 cylinder
    • If this does not restore O2 flow, then the backup cylinder is empty or not properly mounted
  • Conserve O2
    • Terminate mechanical ventilation (if pneumatically powered ventilator)
    • Decrease O2 flows (main and auxiliary flowmeters)
  • May still be able to administer air with inhalational anesthetics even with loss of O2 pressure
  • Obtain additional backup O2 cylinder that fits the anesthesia workstation yoke
  • Ventilate with manual resuscitation bag connected to separate O2 cylinder if no O2 or air flow from anesthesia workstation
O2: oxygen.
