FDA is updating a Draeger Class 1 recall (device correction) of the Perseus A500 anesthesia workstation after receiving reports that the internal backup battery failed spontaneously while the system was being operated off the main power supply. “The battery failure caused unexpected shutdown without a low battery alarm while the device was running on battery power,” a [recall notice](https://www.fda.gov/medical-devices/medical-device-recalls/draeger-inc-recalls-perseus-a500-anesthesia-system-risk-sudden-unexpected-shutdown-when-used-battery?ref=fdaweb.com) says. “If the Perseus shuts down suddenly, patients may not receive enough ventilation (hypoventilation) or enough oxygen (hypoxia) while an alternative form of ventilation is initiated.”

The update recommends that users perform a test of all device batteries and contact Draeger to arrange for replacement batteries if a device fails the test.
