Defibrillators such as the Lifepak 20e and the Zoll R Series are amongst the highly sought-after defibrillation systems which offer a variety of unique features. Defibrillators such as these two can be found in numerous spaces ranging from hospital ICU units, emergency rooms, medical clinics, and other places where there are trained ACLS professionals.

However, there is more that goes into properly using a defibrillator. Understanding how defibrillators work, acquiring proper ACLS training, and knowing what accessories to look for when purchasing defibrillators are critical to saving a life during an emergency—including unexpected circumstances.

To learn more about our two most popular defibrillators—Lifepak 20e and the Zoll R Series—continue reading further.


In summary, a defibrillator is a medical device that delivers an electrical shock through the heart to correct or prevent arrhythmia. This overall process is defibrillation. The purpose of this shock is to restore a heart to its normal heartbeat.

Before doing so, sticky pads with sensors, called electrodes, are attached to the chest of someone who is having a cardiac arrest. The electrodes send information about the person’s heart rhythm to a computer in the AED (Automated External Defibrillator). The computer analyzes the heart rhythm to find out whether an electric shock is needed.



The Physio-Control Lifepak 20e is an advanced defibrillator in the Physio-Control Lifepak line. This Lifepak 20e defibrillator and monitor is highly intuitive for first responders and combines AED and manual capabilities so ACLS-trained clinicians can quickly and easily deliver advanced therapeutic care. The Lifepak is simple yet powerful with special features like capnography, CPR metronome, and the ability to remotely send data to CODE-STAT data review.

Designed for crash cart use, the Physio-Control Lifepak 20e meets all your defibrillator/monitor needs in a compact and affordable package. The Lifepak is simple yet powerful with special features like capnography, CPR metronome, and the ability to remotely send data to CODE-STAT data review.

  • Manual and automatic defibrillation functionality
  • 3 and 5 ECG monitoring capabilities
  • Intuitive door system for both this FDA Approved AED and manual use
  • Built-in AC Power
  • Rechargeable internal lithium-ion battery
  • Compact and lightweight for easy carrying and versatile use


A common question we receive regarding the Lifepak 20e is where the battery goes. The battery door is located on the bottom side of the Lifepak 20e defibrillator. To access the battery, use a small flat-head screwdriver to open the compartment. The Lifepak 20e uses a 12V 6.0Ah Li-ion battery which can be purchased from our medical equipment parts department. You can find the Lifepak 20e battery here. These lithium-ion batteries are lightweight and require a constant current charger that is supplied from the A03 Power Module. The battery on the 20e is used when AC power is no longer available.


The Zoll R Series is known to introduce simple, smart, and ready defibrillation to hospitals and other medical facilities. The two Zoll R models (R Series ALS and R Series BLS) can make code-readiness possible for every hospital department, with advanced cost-effective solutions for resuscitation. Both models are available with pacing, end-tidal CO2, noninvasive blood pressure, and SPO2 monitoring capabilities.

Additionally, the Real CPR Help technology allows the R Series to provide audio and visual feedback that guides rescuers to consistently deliver high-quality CPR.
