I received a call out of hours from a member of theatre staff, the HCU40 in cardiac theatres was alarming "power failure" and sparks were seen coming from the bottom of the device. I advised the nurse to switch off the HCU.

There had been 2 Field Safety Notices issued in recent months recommending replacement of valves and crimping of power cables, however the recommendation in the safety notice had been to continue use as normal.
