Nearly all modern AEDs use what's called a biphasic waveform, a genuine technical improvement over older defibrillator designs worth understanding in plain terms.
What Biphasic Actually Means
A biphasic shock sends electrical current in one direction and then reverses it partway through the shock, compared to older monophasic devices that sent current in a single direction only.
Why This Improvement Matters Clinically
Biphasic waveforms have been shown to be effective at lower energy levels than monophasic technology, reducing potential tissue effects while maintaining strong clinical effectiveness.
Essentially Universal in Current Devices
Every current-generation AED we supply uses biphasic technology — this isn't a premium feature to compare between brands, but a standard baseline across the modern market.
You Don't Need to Understand This to Use a Device Correctly
Like joule specifications, this is background information for the curious rather than something a rescuer needs to know or configure during an actual emergency.
A Sign of How Far AED Technology Has Progressed
Understanding this detail highlights just how much defibrillation technology has genuinely improved since early devices, even though the rescuer's actual experience remains simple.
