Patient suffered a st-elevation myocardial infarction (stemi) and was brought to cath lab after being found down at home.Cardiac cath showed a 100% thrombotic occlusion in the left circumflex artery which was ballooned and stented with a drug-eluting stent (des).The artery was opened down to 0% blockage.Patient suffered acute respiratory failure requiring intubation and ventilator support.Vasopressors were required to maintain his blood pressure.About 6-7 hours post intervention, he had an unexpected drop in his blood pressure.About the same time, the rn went to exchange the levophed iv bag out for a new one as it was nearing empty.The iv pump infusing the levophed started to alarm "cassette failure".Another iv pump was obtained, and they attempted to switch the medication to this pump and it too malfunctioned, stating battery will not charge.The patient proceeded to go into cardiac arrest.Pulseless electrical activity (pea) rhythm was noted, cpr and acls measures were implemented without return of function.After 20 minutes of acls, the patient died.
