Defibrillator Tech Talk: Monophasic vs. Biphasic – What’s the Difference?

a heart with electricity running through it.

If you’ve ever checked out a defibrillator, you might have seen “biphasic waveform” listed as a key feature. Brands tout the fact that their defibrillator is biphasic instead of monophasic.

Today, we’re diving into the world of defibrillator technology and exploring the difference between monophasic and biphasic waveforms. But what does that actually mean? Let’s break it down!

What are Monophasic and Biphasic Waveforms?

First things first, you know how you put two pads on a person who needs defibrillation? The idea is that the electricity runs between those two pads and shocks the heart.

Monophasic and Biphasic describe the way the electricity runs between those two pads.

Monophasic waveforms are like a one-way street. They deliver a single, high-energy electrical pulse that flows in one direction from one pad to the other.

On the other hand, biphasic waveforms are more like a two-way street. They quickly shoot a pulse in one direction but then reverse it the other way, all in the same shock!

It’s like the electricity does a U-turn in the heart!

Why Biphasic is the Way to Go

So, why are biphasic waveforms the preferred choice in modern defibrillators? Here are a few reasons:

  1. Lower Energy, Same Results: Biphasic waveforms are more efficient at getting the job done. They require less energy to reset the heart’s rhythm compared to monophasic waveforms. That means a gentler shock for the patient.
  2. Smaller. Biphasic technology has allowed for the creation of more compact defibrillators meaning it’s easier to get one into your hands.

DDI Safety: All About That Biphasic Life

So to recap: What’s the difference between monophasic and biphasic defibrillators? Monophasic gives the shock one way, Biphasic gives the shock both ways

At DDI Safety, we’re all about staying on the cutting edge of defibrillator technology. That’s why our devices feature state-of-the-art biphasic waveforms. When you choose a DDI Safety defibrillator, you can feel confident that you’re getting the latest and greatest in life-saving tech.

Stay safe, stay informed, and keep on shocking!
