It was reported that the rn from the intensive care unit called due to loss of ap (arterial pressure) waveform on the intra-aortic balloon pump (serial number (b)(4)).The rn stated the 40cc fluid filled intra-aortic balloon (iab) was inserted less than 12 hours ago for a patient with stemi (segment elevation myocardial infarction).Just recently, the ap waveform flattened and "no ap waveform available" message appeared on the pump.The pump was in autopilot utilizing pattern trigger.Heparinized nss (normal saline solution) flush was connected to the central lumen.The sheath sideport was connected to the bedside monitor with a "dampened" ap tracing.The clinical support specialist (css) verified that there was no disruption in pump and the iabp continued to pump using the ecg tracing.The rn was unable to fast flush or aspirate the central lumen.The css explained this would indicate that the central lumen is no longer patent and an alternative ap source needed to be brought to the pump.The rn was able to transduce the sideport directly to the pump console and ap waveform was now present on iabp.The css explained why the sideport had a dampened waveform and another ap source may ned to be obtained (radial arterial line) if the sideport is not consistent or too dampened.The css requested that the rn mark the central lumen as clotted and to save the iab after removal for return.Pump strips were not generated, x-rays were not performed and as a result, strips and x-rays are not available for review.The outcome of the patient is noted as the patent is still on pump.
