Reason for recall

Philips has received a number of reports of HeartStart MRx Monitor/Defibrillators that have suffered internal damage and were not able to deliver therapy after having been dropped or subjected to a severe mechanical shock, even though the device did not have visible external damage or the Ready for Use ( RFU ) indicator on the unit did not immediately indicate a problem. One of these reports involved a death of a patient who could not be resuscitated.
