A few years ago I performed CPR on a neighbor. I had practiced it many years ago, but I was uncertain about the frequency and depth of the compression strokes. I talked to the 911 operator who guided me. I put this little GIF on the blog to remind me and anyone who reads the blog to know how often and how deep your compression strokes should be.
Sadly, my neighbor did not survive. More about CPR from the American Heart Association at:

CPR – or Cardiopulmonary Resuscitation – is an emergency lifesaving procedure performed when the heart stops beating. Immediate CPR can double or triple chances of survival after cardiac arrest.
The American Heart Association invites you to share our vision: a world where no one dies from cardiac arrest. Every year, 350,000 people die from cardiac arrest in the United States. Big number. Bigger opportunity. With your help, we can bring that number down to zero.
Why Is CPR Important?
Keeping the blood flow active – even partially – extends the opportunity for a successful resuscitation once trained medical staff arrive on site.
Chain of Survival
CPR is a critical step in the AHA’s Chain of Survival. The term Chain of Survival provides a useful metaphor for the elements of the ECC systems concept.
The 6 links in the adult out-of-hospital Chain of Survival are:
- Recognition of cardiac arrest and activation of the emergency response system (calling 9-1-1 in the US)
- Early CPR with an emphasis on chest compressions
- Rapid defibrillation
- Advanced resuscitation by Emergency Medical Services and other healthcare providers
- Post-cardiac arrest care
- Recovery (including additional treatment, observation, rehabilitation, and psychological support)
A strong Chain of Survival can improve chances of survival and recovery for victims of cardiac arrest.
Automated External Defibrillators (AED)
AEDs can greatly increase a cardiac arrest victim's chances of survival. The AHA offers a two-page guide on how to implement an AED program at a company or organization. To minimize the time to defibrillation for cardiac arrest victims, deployment of AEDs should not be limited to only trained people (although training is still recommended).How is CPR Performed?
There are two commonly known versions of CPR:
- For healthcare providers and those trained: conventional CPR using chest compressions and mouth-to-mouth breathing at a ratio of 30:2 compressions-to-breaths. In adult victims of cardiac arrest, it is reasonable for rescuers to perform chest compressions at a rate of 100 to 120/min and to a depth of at least 2 inches (5 cm) for an average adult, while avoiding excessive chest compression depths (greater than 2.4 inches [6 cm]).
- For the general public or bystanders who witness an adult suddenly collapse: compression-only CPR, or Hands-Only CPR. Hands-Only CPR is CPR without mouth-to-mouth breaths. It is recommended for use by people who see a teen or adult suddenly collapse in an out-of-hospital setting (such as at home, at work, or in a park).
Hands-Only CPR consists of two easy steps:
- Call 9-1-1 (or send someone to do that)
- Push hard and fast in the center of the chest
About High-Quality CPR
High-quality CPR should be performed by anyone - including bystanders. There are five critical components:
- Minimize interruptions in chest compressions
- Provide compressions of adequate rate and depth
- Avoid leaning on the victim between compressions
- Ensure proper hand placement
- Avoid excessive ventilation
