Dear Owners of the samaritan® PAD 500P,
The purpose of this letter is to inform you of a corrective action that HeartSine Technologies Ltd.
is introducing in relation to samaritan® PAD 500P public access defibrillators.
The corrective action is intended to address an issue that could affect the accuracy of the CPR
(cardiopulmonary resuscitation) instructions provided to rescuers by the samaritan® PAD 500P Defibrillator during a sudden cardiac arrest situation.
HeartSine Technologies’ records indicate that you have received a samaritan® PAD 500P device
which is affected by this action.
Issue identified
The samaritan® PAD 500P Defibrillator is intended, where appropriate, to deliver shocks to victims of a
sudden cardiac arrest and has a secondary function to provide feedback to rescuers concerning
the effectiveness of the CPR they are providing.
The corrective action described in this Upgrade is for Product Correction relates to this secondary function.
The software in your samaritan® PAD 500P may miscalculate the CPR rate of compression per
minute being administered to the patient.
The rescuer may, therefore, be incorrectly advised by
the device to “Push Slower” when, in fact, the CPR rate is at an acceptable level. There are reports
of death and serious injury during the use of the samaritan PAD 500P devices, and in two cases
the incorrect CPR feedback given to the user cannot be eliminated as being a contributory factor
to the patient outcome.
Any samaritan® PAD 500P Defibrillator devices manufactured between February 2010 and January 2014 with
the following serial numbers inclusive are affected by this issue:
· 10B0010001 to 14B00461703
