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.

GE Healthcare issued an "URGENT MEDICAL DEVICE CORRECTION" notice to its consignees on 11/14/2025 via letter using a traceable means. The notice explained the issue, safety issue, and requested the following actions be taken by Customer/User: "Pending correction by GE HealthCare, you can continue to use the Anesthesia machine with affected power management boards by following the instructions below: 1. Always ensure the device has a secure connection to an AC mains power source. 2. If there is a loss of AC mains power to the system leading to an unexpected system shutdown: - Promptly initiate ventilation using a self-inflating bag connected to an oxygen source. - Assess oxygenation via pulse oximetry. - Because volatile anesthetic agent delivery may transiently be disrupted, supplement with or transition to intravenous anesthetics as needed. - Following system reboot, the system will enter pre-use check. Press "Start Anesthesia or Start Case and then select the "Bypass" button to bypass the checkout. Proceed to selecting the ventilation parameters and volatile agent concentration appropriate for the patient. Please ensure all potential users in your facility are made aware of this safety notification and the recommended actions. Please retain this document for your records. Please complete and return the attached acknowledgement form to [email protected] or submit the acknowledgment using survey."
