Event or Problem Description
It was reported that an s3 alarm occurred during a patient transport within a hospital.The customer stated that while transporting a centrimag venovenous extracorporeal membrane oxygenation (vv-ecmo) patient, the centrimag console was plugged into a battery backup/power strip device.The s3 alarm did not resolve when they plugged the battery backup device into a hospital emergency outlet.The customer was advised to discontinue the use of the power strip and to switch to another centrimag console and motor that was plugged directly into a red hospital ac power outlet.The customer stated that they did not want to switch to another device at this time as the patient was considered a do not resuscitate (dnr) and that somehow switching to another device would be a problem.Several hour later the customer switched to another centrimag console yet continued to use the battery backup/power strip device and the 2nd centrimag system also displayed an s3 alarm.
