The LIFEPAK CR2 AED is uniquely designed for use by laypersons with little to no formal AED training. It’s ideal for both public and commercial settings where the first person to respond to a Sudden Cardiac Arrest event will often lack medical foreknowledge. Its water resistant and lightweight design, coupled with the newest ADAPTIV biphasic technology that automatically adjusts voltage based on each victim’s specific defibrillation needs, make it an optimal choice for high-traffic areas. It additionally has the capability to escalate the energy delivered to a market-leading 360 joules if necessary.
 
A Semi-Automatic AED will read the victim’s underlying heart rhythm and if it detects a shockable rhythm, it will prompt the rescuer to push the Shock Button in order to deliver the electrical shock.
