Cpr Quality; Impedance Cardiogram - HeartSine samaritan PAD SAM 500P User Manual

Introduction

CPR quality

When providing cardiopulmonary
resuscitation (CPR) treatment to a victim
of sudden cardiac arrest, it is vital the
chest compressions are of a good quality.
If the quality of the CPR provided is good,
the chances of successfully resuscitating a
patient are greatly increased.
Research has demonstrated that non-
professional responders regularly provide
ineffective CPR due to inexperience. As
a response to this problem, HeartSine
has developed the SAM 500P with
CPR-Advisor.
The SAM 500P with CPR-Advisor can
provide feedback to rescuers on the
effectiveness of the cardiopulmonary
resuscitation (CPR) they are providing
to the victim. The SAM 500P uses
ICG measurements to analyse the
effectiveness and rate of compressions
given and then, based on this analysis,
advises the rescuer to push harder, faster
or slower as appropriate. The SAM 500P
uses both audible and visual prompts to
give the responder feedback on the quality
of the compressions administered.
Warning: The CPR Advisor
function is intended for use
on adult patients only. If a
Pediatric-Pak is used, the CPR
function is disabled. In this
case, the rescuer is prompted
to begin CPR but receives no
CPR Advisor feedback.
Impedance cardiogram (ICG)
The impedance cardiogram is a method
of measuring changes in the patient's
impedance due to motion, blood flow and
changes to the shape of the heart. The
SAM 500P uses these measurements
to estimate the impedance changes in
the chest and so as a way to determine
the effectiveness of compressions given
during CPR.
