HeartSine samaritan® PAD 450P AED

Real-time CPR feedback to support higher-quality response

The HeartSine samaritan PAD 450P AED is designed for organizations that want additional guidance during cardiac emergencies. In addition to delivering semi-automatic defibrillation, the 450P provides real-time feedback on CPR compression rate, helping responders maintain effective CPR while care is underway.

Designed to support responders under pressure

In many workplace emergencies, responders may have varying levels of CPR experience. The PAD 450P includes integrated CPR rate feedback that provides visual and voice cues such as “push faster,” “push slower,” or “good speed,” helping guide consistent chest compressions during resuscitation.

This added feedback can be particularly valuable in environments where AEDs may be used infrequently, and responders benefit from real-time reinforcement.

Product Highlights

HeartSine samaritan PAD 450P

The semi-automatic HeartSine samaritan PAD 450P combines defibrillation capability with integrated CPR rate guidance in a compact, lightweight design suitable for workplace and public-access settings.

  • Semi-automatic shock delivery with guided voice prompts

Ready for consistent use

Automatic self-tests monitor device status, battery condition, and pad readiness. Visual indicators make it easy to confirm the AED is ready for use during routine inspections.

Simplified ownership and maintenance

The HeartSine Pad-Pak system combines the battery and electrode pads into a single cartridge with one expiration date. This design helps reduce maintenance complexity and supports predictable replacement planning as part of an AED program.

Clinically validated defibrillation technology

The PAD 450P uses HeartSine’s SCOPE biphasic waveform, which automatically adjusts energy delivery based on patient impedance to support effective defibrillation.
