The production device history record (dhr) for this intra-aortic balloon pump (iabp) was not required to be reviewed per the company standard operating procedure since the device manufacture date is greater than one year from the event date.A getinge field service engineer (fse) was dispatched to evaluate this unit and replaced the helium tank.Additionally, upon evaluation of the iabp itself, the fse found that the internal helium tank pressure dropped by approximately 150 psi in a 5-minute period.To confirm if there were leaking points, the fse applied "gas leak check liquid spray" on the surface of the unit and tubing connections inside the unit and on the hospital cart and was able to identify the leaking point.The fse then disassembled parts of the fill manifold (cv1) and found that the o-ring was damaged.To resolve the issue, the fse replaced the o-ring.However, the iabp is still under observation and has not been released for clinical use.A supplemental report will be submitted upon completion of evaluation.
