You have made an excellent decision to narrow the search on HeartSine for your Automated External Defibrillator (AED). Known for their compact design, user friendliness, and robust engineering, HeartSine Samaritan PADs are a leading choice for homes, schools, and businesses. But now you face a critical question, should you choose the Samaritan PAD 350P or invest a little more in the Samaritan PAD 450P?
While they look nearly identical, the key difference between them, the 450P’s CPR Rate Advisor, can have a significant impact on a rescue's outcome. We will walk you through that difference, helping you decide not just on price, but on the level of guidance you want to provide a potential rescuer during a life or death moment.
The foundation of both great choices
Before we look at the differences, it’s important to recognize what makes both the 350P and 450P exceptional devices. Both models are built on the same core platform, offering features that make them ideal for public spaces and lay rescuers.
-
Compact and lightweight:
They are some of the smallest and lightest AEDs available, making them easy to store and carry to a victim’s side. -
User-friendly Interface:
Simple, clear voice and visual prompts guide the rescuer through every step of the process. -
Durability:
Both devices have an IP56 rating, providing high resistance to dust and water, ensuring they are ready even in harsh conditions.
-
Simplified maintenance:
They use a single, integrated Pad-Pak cartridge that contains both the battery and electrode pads. This cartridge has one expiration date, eliminating the need to track two separate components and making upkeep incredibly simple.
Either model provides a top-tier, reliable AED. The decision comes down to understanding the vital role of CPR during a rescue.
The critical role of CPR in saving a life
When a person experiences Sudden Cardiac Arrest (SCA), their heart stops beating effectively. An AED is designed to deliver an electrical shock to reset the heart's rhythm, but that’s only half the battle. In the minutes before a shock is delivered and the moments after, high-quality CPR is what keeps oxygenated blood flowing to the brain and other vital organs.
Effective CPR is about more than just pushing on the chest, it requires the right rate and depth. For a lay rescuer, especially one who is panicking, remembering the correct pace of 100 to 120 compressions per minute can be nearly impossible. This is where the two models diverge. While the 350P provides the life-saving shock, the 450P goes a step further by actively coaching the rescuer on their CPR performance.
The key difference the CPR rate advisor
The single most important advantage of the HeartSine Samaritan PAD 450P is its integrated CPR Rate Advisor. This technology is designed to solve one of the biggest challenges for rescuers, performing chest compressions at the correct speed.
How does it work
The 450P uses its defibrillation pads to conduct an Impedance Cardiogram (ICG). This is a sophisticated way of saying the device can measure changes in the electrical impedance of the chest wall as the rescuer performs compressions. Based on these measurements, the AED determines if the compression rate is correct. This is all done through the standard pads, requiring no extra sensors or pucks that could complicate the rescue.
What does it do for the rescuer
Based on the rate it detects, the 450P provides simple, direct, real-time feedback. The voice prompt will instruct the rescuer to “Push faster,” “Push slower,” or will affirm their technique with “Good speed.” An integrated gauge on the device also gives a visual cue.
This feedback is invaluable. It removes the guesswork and anxiety from performing CPR. For a teacher, an employee, or a family member who has never performed CPR in a real emergency, this coaching transforms them from a nervous bystander into a confident and effective first responder. It ensures the victim receives high-quality compressions, which is a critical link in the chain of survival.
Making the right choice for your environment
So, which device is right for you? The answer depends on who you expect the potential rescuer to be.
Who is the Samaritan 350P for
The HeartSine Samaritan PAD 350P is an outstanding and cost-effective AED. It is perfectly suitable for environments where rescuers are likely to be medical professionals or individuals who receive frequent, high-level CPR training and may feel more confident in their ability to maintain the correct pace without live feedback. It provides the essential life-saving shock with the same reliability and ease of use as the 450P.
Why the Samaritan 450P is the recommended choice for most
For a home, school, community center, or small business, the reality is that the first responder will likely be a layperson with minimal training and no real-world experience. In the chaos of an emergency, the CPR Rate Advisor on the HeartSine Samaritan PAD 450P is a game-changer. It provides an essential layer of support that builds rescuer confidence and directly improves the quality of CPR.
This isn't just about an extra feature, it's about empowering anyone to deliver better care. When you consider the small difference in cost, investing in the 450P is an investment in a better chance of survival.

Frequently asked questions
Q: Is the CPR feedback on the 450P really necessary if we get CPR training?
A: CPR training is absolutely essential, and we encourage it for everyone. However, even with training, it's difficult to recall the exact pace of 100-120 compressions per minute under the stress of a real emergency. The 450P's real-time feedback acts as a live coach, ensuring the rescuer maintains the optimal rate and delivers the most effective care possible.
Q: Do both the 350P and 450P use the same battery and pads?
A: Yes. Both the 350P and 450P use the innovative HeartSine Pad-Pak, which is a single, easy-to-manage cartridge containing both the electrode pads and the battery. The Pad-Pak has a four-year lifespan and simplifies maintenance by giving you only one expiration date to track.
Q: Is the 450P much more expensive than the 350P?
A: While the 450P has a higher upfront cost, the investment is relatively small for a feature that directly improves the quality of life-saving CPR. When purchased as part of a value package, the difference in price is often minimized, making the advanced technology of the 450P highly accessible and a wise investment in preparedness.
Q: Can I use the 450P on a child?
A: Yes. For children under 8 years of age or weighing less than 55 lbs (25 kg), you can use the HeartSine Pediatric-Pak. When this special Pad-Pak is inserted, the device automatically recognizes it and reduces the energy of the defibrillation shock to a level appropriate for a child. The CPR Rate Advisor functions with the Pediatric-Pak as well.
