Brief power outage to entire hospital.Back-up power came on within a few seconds.Patient was having an angiogram procedure when this happened.When the power went out, and the back-up power came on, it took 30 minutes for the siemens computer to reboot.There was no fluoroscopy during this time.Completion of the angiogram was delayed until the computer rebooted.When the main power came back on, the computer rebooted again.The computer then took another thirty minutes to reboot.No injury to patient.Patient did well.However, procedure time was extended due to waiting for the computer to reboot.Siemens was notified of the event by the hospital clinical engineering dept.Siemens is working to develop a fix for this problem (i.E.Computer should continue working without having to reboot).
