Intended Use
The M3500B HeartStart XLT Defibrillator/Monitor is for use by emergency
personnel trained in the operation of the device and qualified by training in
basic life support, advanced cardiac life support, defibrillation, or ot her physi-
cian-authorized emergency medical response. It must be used by or on the
order of a physician.
When operating as a semi-automatic external defibrillator in AED Mode, the
HeartStart XLT is suitable for use by heal th ca re profe ssiona ls t raine d in basic
life support that includes the use of an AED.
When operating as a defibrillator/monitor in Manual Mode, the HeartStart
XLT is suitable for use by health care professionals trained in advanced car-
diac life support.
Defibrillation Therapy
Defibrillation therapy is the definitive method for termination of a variety of
potentially fatal arrhythmias. The Hea rtStart XLT provides this therapy
through the application of a brief biphasic pulse of electricity to the cardiac
muscle. This electrical energy is transferred through disposable multifunction
defib electrode pads applied to the patient’s bare chest.
NOTE Successful resuscitation is dependent on many variables specific to the
patient’s physiological state and the circumstances surrounding the patient
event. Failure to have a successful patient outcome is not a reliable indicator
of defibrillator/monitor performance. The presence or absence of a muscular
response to the transfer of energy during electrical therapy is not a reliable
indicator of energy delivery or device performance.

Indications for AED Therapy

An AED is to be used in the presence of a suspected cardiac a rr est o n p ati en ts
that are:
Unresponsive
Not breathing
Pulseless
