In 1952, Dr Paul M. Zoll  discovered while working as Chief of Cardiac Clinic that an external electrical stimulation of a patient suffering cardiac arrest could revive the patient.  For the next 25 years Dr. Zoll committed his efforts to furthering the science of defibrillation before founding the Zoll Medical Corporation in 1992.  Zoll is now a leading manufacturer and supplier of advanced automated external defibrillators for Emergency Medical Services, Publish Safety, Hospitals, Military, and Home Land Defense.

Zoll AED Plus Defibrillator 
The Zoll AED Plus is an advanced defibrillator with real-time feedback to the rescuer to guide the caregiver throughout the CPR process by monitoring in real-time compressions.  The Real CPR Help system will monitor rate and depth of compressions and provide feedback:

• Not pushing hard enough? It will tell you when to push harder.
• Pushing hard enough? It will say, "Good compressions."
• Not pushing fast enough? A metronome will lead you to the right rate.
• It will even show you the depth of each compression. In real time.
• Not yet started? The AED Plus will tell you again to get started.
• Compressions stopped? It will tell you to continue.
  
  
  
  
  
  

The Zoll AED Plus also employs Intelligent Pediatric Capabilities allowing the devices to be used on adult and child / infants.  Once the Zoll Pedi-Padz II are connected it will tell the rescuer the electrodes are connected properly and ready for use.  The Zoll AED Plus has build in algorithms to separate energy levels between adult and children automatically instead of relying on resistors that other manufacturers use. 

Another advantage of the Zoll AED pads is they use a one-piece electrode pad which simplifies placement of the pads since there isn’t a left or right pad.  This further helps the caregiver in an emergency by eliminating the need to check left or right on the pads.

The AED has a high resolution LCD screen allowing care givers to visualize a patient's ECG. Also, unique to the ZOll AED Pro and Plus is the real-time feedbak system known as Real CPR Help. Real CPR Help measures the caregivers CPR to determine the rate and depth of compressions. With audible and visual prompts it will help optimize CPR by proivding real-time insturctions.
