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 | |
|
- Loss of pipeline O2 supply
|
|
|
- O2 pipeline hose disconnected
|
|
Suggested responses | |
- If this does not restore O2 flow, then the backup cylinder is empty or not properly mounted
|
|
- 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
