PocketCPR FAQ's
Here are some answers to the most common questions about PocketCPR.

I Have Taken CPR Training. Why Do I Need PocketCPR?
Performing CPR is physically and mentally demanding. PocketCPR can increase confidence and reinforce skills learned during CPR training. It is the hope that with PocketCPR, bystanders will be more willing to help save a life. top of page

I Feel Confident and am Experienced in CPR. Why Do I Need PocketCPR?
Studies have shown that audible prompting during CPR can improve the delivery of CPR and prevent the decrease of compression rate and depth that naturally occurs with fatigue. Recent data has shown that real-time CPR coaching and feedback can improve both pre-hospital and in-hospital CPR quality. 1,2,3,4,5,6, top of page

How Does CPR with PocketCPR Help Save a Victim’s Life?

  • According to the American Heart Association, brain death and permanent death start to occur in just 4 to 6 minutes after someone experiences cardiac arrest. Cardiac arrest can be reversed in most victims if treated with immediate CPR and an electric shock to the heart within 7 to 10 minutes.
  • Each minute that passes without CPR increases the rate of death by 10% for someone experiencing sudden cardiac arrest.
  • It’s rare for someone who is not resuscitated pre-hospital to survive with good neurological function.
  • PocketCPR can coach the rescuer to perform good CPR and restore up to 30% of normal blood flow, enough to keep the heart and brain functional until help arrives. top of page

Why Choose PocketCPR?
PocketCPR is the only hand-held device that reminds the rescuer what to do before initiating CPR and coaches the rescuer with audible and visual feedback during CPR. top of page

Is PocketCPR Cleared by the FDA?
Yes. PocketCPR received FDA clearance in November of 2007. top of page

How Does it Work?
PocketCPR measures compressions with an embedded sensor, called an accelerometer, that measures the depth and rate of chest wall movement during each compression. A sophisticated microprocessor in the device continuously measures acceleration during each compression, and special algorithms convert acceleration information into distance traveled. PocketCPR utilizes the same Real CPR Help® technology found in ZOLL defibrillators. top of page

Who Can Use PocketCPR?
