A getinge field service engineer (fse) was dispatched to evaluate the iabp unit and was able to reproduce the reported issue.The sudden shutdown of the appliance was caused by an error internal communication between boards.The fse disassembled all the internal cards with the relative wiring, carefully checked and cleaned all the connectors.With special simulator performed many tests of correct use at various levels of tolerance for the machinery (ecg from 60bpm to 130bpm).The fse completed all safety, functionality, and calibration checks and all tests passed to factory specifications.The iabp was then released to the customer and cleared for clinical service.
