Medtronic Stryker Physio-Control Lifepak 20e Defibrillator


In an emergency, knowing how to use a defibrillator could save someone’s life. You can find defibrillators in numerous public places besides hospitals and other medical facilities. Businesses and schools are some of the places that often have defibrillators in case of use for emergencies. Soma Technology has one on every floor at all our facilities, on the unfortunate off-chance, it will be needed before an ambulance arrives. This need is predicated on the idea that at any time, someone can fall ill and need to be immediately revived.

There is more that goes into the actions of properly using a defibrillator than what is typically depicted on screen. Especially, the knowledge of how defibrillators work and the training involved in becoming certified to use them. Knowing how a defibrillator works can help you act more effectively in a stressful situation. The Likepak 20e Defibrillator offers the right tools to monitor, document, and review events. Let us continue further on what you need to know about this defibrillator.


A defibrillator is a medical device that delivers an electrical shock through the heart to correct or prevent an arrhythmia. This process is called defibrillation. The goal of this shock is to restore a heart to its normal heartbeat.

There are different kinds of defibrillators in use today. Here are some examples:


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. The computer analyzes the heart rhythm to find out whether an electric shock is needed. If needed, the electrodes deliver the shock.

Please check your local hospitals, community centers, police departments, and other government services to see if they are offering classes in both defibrillation and CPR.


An AED should be used when a person is in distress, has collapsed, is unconscious, or has symptoms of a heart attack. The common symptoms of a heart attack, or myocardial infarction, are nausea, heavy breathing, and pain down the arm, shoulder, back, or jaw. Thus, AEDs like the FDA-approved Lifepak 20e are extremely important because they strengthen the Chain of Survival.


The Physio-Control Lifepak 20e is clinically the most 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 that ACLS-trained clinicians can quickly and easily deliver advanced therapeutic care. The CodeManagement Module adds waveform capnography and wireless connectivity to enhance your hospital’s ability to effectively manage resuscitations from preparedness through review. The CodeManagement Module adds additional capabilities to the 20E to help aid in how your facility manages codes.

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.

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 12Volt 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 by the A03 Power Module. The Battery on the 20e is used when AC power is no longer available.


Soma Tech Intl offers the Lifepak 20e defibrillator up to 50% below OEM prices with the same service and warranty as new. Soma Tech supplies medical equipment from top manufacturers like Physio-Control. When these defibrillators come to our facility they are carefully inspected and tested. Then, our in-house biomedical engineers replace parts and components if necessary. The defibrillator is continuously tested until all aspects of the unit are in working order. Then, the device is calibrated back to the original engineering manufacturer’s specifications. After the defibrillator is working like new, Soma makes it LOOK like new. It undergoes a special cosmetic restoration process where it gets cleaned, minor scratches and dents are repaired, the unit is repainted, and decals are replaced if necessary. Once this special restoration process is completed the unit goes through one final quality control check to ensure the unit is patient-ready. It’s visually and physically inspected and tested again. When it passes the final inspection and tests it is labeled patient-ready and packaged up for shipment.


Soma Tech Intl has a large medical accessories division to support the medical devices sold.  offers power charging stations, non-rechargeable lithium battery packs, data cards, fast response kits, crash carts, and more. Other accessories and parts include the carrying case, adult/pediatric pads, owner’s manual, alarms, and countless other products.
