  Aisys, Datex-Ohmeda anesthesia system, Part Number 1011-9050-000

  Anesthesia Delivery Systems containing certain electronic gas mixer assemblies can automatically transition to Alternate O2 control. In Alternate O2 control, the system delivers 100% O2 to the breathing system enabling continued controlled or manual ventilation and initiates audible and visual alarms. When this issue occurs, anesthetic agent delivery will be interrupted and requires clinician intervention. If this is not provided, the patient may experience decreased anesthetic agent effect.

  Potential unexpected shutdown of Carestation 600 and 700 Series Anesthesia Systems containing certain power management boards, if the AC mains power is unplugged or in the event of an AC mains power failure. Anesthesia systems only operate on battery power in a rare event that AC mains power is lost and there is no continuous backup emergency power. If AC power is interrupted, the system will not automatically switch over to the battery supply mode and will reboot. If this issue occurs, a temporary disruption of mechanical ventilation, manual ventilation, and volatile agent delivery may occur. Following the reboot, the system will not return to the previous ventilation settings.
