Intraoperative Mains Oxygen Supply Failure - Guidelines for Crises in Anaesthesia Complete failure of wall or pendant oxygen supply. Failure may be theatre-specific, zone-specific or hospital-wide ❶ Inform the theatre team of the problem, including theatre coordinator (Box A). ❷ Call for help, but be aware failure may be widespread. ❸ Switch to cylinder oxygen supply. ❹ Check remaining cylinder content (Box B): • Ensure at least one further cylinder always available. ❺ Prolong duration of cylinder oxygen supply: • Use circle system. • Use lowest possible fresh gas flow. • Use lowest possible FiO2. • Check FiO2 alarms. ❻ Minimise auxiliary gas usage: • Some ventilator systems are gas-driven. If so, switching to manual ventilation will prolong oxygen cylinder supply. ❼ Evaluate moving to nearby area if oxygen supply there preserved. ❽ Continue to monitor and ensure adequacy of inspired oxygen and volatile agent. ❾ Workflow: • Do not start any new case unless clinical priority absolutely requires it. • Expedite conclusion of current case if clinically appropriate. • Consider recovering the patient in theatre if recovery also affected (Box C). ❿ Disconnect from failed outlets and do not re-connect until safe to do so (Box D).
