Federal safety officials have issued an urgent warning about software
defects in an anesthesia delivery system that can cause life-threatening
failures at unexpected times, including when a cellphone or other device
is plugged into one of its USB ports.
The ARKON anesthesia delivery system is used in hospitals to deliver
oxygen, anesthetic vapor, and nitrous oxide to patients during surgical
procedures. It is manufactured by UK-based Spacelabs Healthcare Ltd.,
which issued a recall in March. A bug in Version 2.0 of the software
running on the device is so serious that it could cause severe injury or
death, the US Food and Drug Administration warned last week in what's
known as a Class I recall. In part, the FDA advisory read:
Reason for Recall: Spacelabs Healthcare is recalling the ARKON
Anesthesia System with Version 2.0 Software due to a software defect.
This software issue may cause the System to stop working and require
manual ventilation of patients. In addition, if a cell phone or other
USB device is plugged into one of the four USB ports for charging, this
may also cause the System to stop working.
This defect may cause serious adverse health consequences, including
hypoxemia and death. Spacelabs Healthcare received one report related to
the software defect. There has been no injuries or deaths associated
with this malfunction.
