About HeartSine 500P

Regardless of whether it is a layperson or a professional rescuer, AHA/ERC Guidelines place a greater emphasis on the importance of effective CPR in increasing survival rates after out-of-hospital cardiac arrest.

HeartSine® samaritan® PAD 500P defibrillator with CPR Advisor is the most innovative device available to support these guidelines, giving rescuers feedback on the effectiveness of their CPR efforts – in real time.

Visual indicators let the user know if effective CPR is being administered. Voice prompts let the user know if chest compressions are being given correctly. Aural “clicks” help the user keep time.

How It Works

The 500P defibrillator provides the rescuer with real-time instructions regarding compressions with audible “Good Compressions” or “Push Harder,” “Push Faster” and “Push Slower.” These instructions also are displayed on the face of the device in order to ensure the rescuer performs the most effective CPR.

CPR, Cardio (heart) Pulmonary (lung) Resuscitation, combines compressing the heart to circulate blood to all the vital organs and, at the same time, breathing into the victim to supply oxygen.

Impedance Cardiogram (ICG) analysis is embedded in the software, which guides the user in the required force and speed of compressions for the victim. The ICG measures impedance changes in the chest cavity, which helps determine effective CPR. Because the ICG is related to how fast the compressions are applied, as well as how hard, the 500P can guide the user on both rate and depth.

After being instructed to “Begin CPR,” an audible beep for the appropriate cadence will help the rescuer keep time when performing compressions. The objective during CPR using the 500P is to hear “Good Compressions” and to see green on the CPR indicator.

Defibrillation is easy, CPR is the hard part. The HeartSine samaritan PAD 500P provides all the advantages of the 300P/350P with the addition of an innovative CPR Advisor. Regardless of whether it is a layperson or a professional rescuer, the AHA/ERC guidelines place a greater emphasis on the importance of CPR and advocate the prompt initiation of effective bystander CPR to significantly reduce mortality due to out-of-hospital Cardiac Arrest.

This Device Has Many Unique Features Including:

Live CPR feedback based on real-time blood flow. ICG (impedance cardiogram) technology.

2 button operation with clear and simple voice and visual prompts.

HeartSine defibrillators are the easiest to maintain with their combined battery and electrode cartridge, known as the Pad-Pak, which only needs to be replaced every 4 years or following an event. This can be changed simply in just 5 seconds.

HeartSine defibrillators have a charging time of just 8 seconds.

Providing protection against dust and water ingress.

The impedance operating range of the HeartSine devices is 20-230 ohms which is greater than other defibrillators available. This means it will deliver a lifesaving shock in more cases than other defibrillators due to its advanced Self-Compensating Output Pulse Envelope (SCOPE) technology.

Easy-To-Follow Visual And Verbal Guide

User Friendly

Easy-to-understand visual and voice prompts guide a user through the entire process.

Built-in confidence

The samaritan PAD 500P uses an Impedance Cardiogram (ICG) to assess the effectiveness of the CPR and give the rescuer feedback on compressions.

Always Ready

A System Status Ready Indicator flashes to show that the complete system is operational and ready for use. The device automatically runs a self-check each week.

Compact In Size, Long On Ability

Highest level of dust/moisture protection

The samaritan PAD has a rating of IP56, providing the 500P defibrillator with the highest level of protection from dust or moisture ingress in the industry.


The samaritan PAD 500P resists shock and vibration and carries a ten-year unit warranty that demonstrates the reliability of this quality unit.

Advanced Technology

The samaritan PAD 500P utilizes proprietary electrode technology, advanced and stable firmware, and proprietary SCOPE™* Biphasic technology (an escalating and low-energy waveform that automatically adjusts for patient impedance differences) to assess rhythm and recommend defibrillation if necessary.​

Samaritan Pad Footprint 28% - 56% smaller

*Self-Compensating Output Pulse Envelope (SCOPE) technology automatically compensates energy, slope and pulse envelope for the patient.
