Product Description

Aisys CS2, Datex-Ohmeda anesthesia system, Part Number 1011-9055-000

Reason for Recall

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.

Distribution Pattern

Class I recalls indicate a reasonable probability of serious adverse health consequences or death from the defect. Class II recalls involve products that may cause temporary or medically reversible adverse health consequences, or where serious consequences are remote.

The classification guides urgency, Class I recalls require immediate action, while Class III may simply involve returning a product or acknowledging a labeling change. Always read the specific recall notice for recommended patient actions.
