The production device history record (dhr) for this intra-aortic balloon pump (iabp) was not required to be reviewed per company standard operating procedure since the device manufacture date is greater than one year from the event date.
A getinge service territory manager (stm) was dispatched to the customer's site to investigate the reported issue.
The stm ran a performance test and the iabp repeatedly generated a ¿low vacuum¿ and ¿rapid gas loss¿ alarms.
The stm replaced the compressor vacuum and the pressure heads and membranes as a part of the 5,000 hour rebuild.
However, the vacuum alarm persisted.
The stm then replaced the purge valve assembly along with the purge line, which resolved the issue.
The iabp passed all functional, calibration and safety tests as per factory specifications.
The iabp was returned to customer and cleared for clinical use.
