Reason for Recall: The affected anesthesia delivery systems may have a gasket leak which could cause an interruption of or inadequate patient anesthesia and ventilation, temporary or permanent patient injury, or death. Facilities should consider having backup equipment to maintain patient ventilation in the event of device failure due to this issue.
The gasket leak could also cause injury to bystanders and operating room personnel due to exposure from leaking anesthesia gases.
The company has identified the cause of the leak as a small step in the gasket surface which may interfere with the full seating of the gasket within the canister. The leak may be identified during the Automatic Circuit Leak and Compliance Test performed at start up and during the Manual Leak Test recommended before each use.

FDA Comments: Mindray first informed customers about this recall in a letter, dated August 8, 2012. The letter identified the problem with the device and possible adverse effects on patients.
There have been no reports of injuries associated with this problem. Mindray became aware of the issue when a system leak was reported by a customer.
Mindray is in the process of correcting the leak issue by replacing canister gaskets on affected devices. According to the company, as of November 14, 2012, approximately 70% of units affected by this action were corrected.
