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.
Keeping the blood flow active – even partially – extends the opportunity for a successful resuscitation once trained medical staff arrive on site.
There are two commonly known versions of CPR:
1.) 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]).
2.) 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).
Occurs when the heart malfunctions and stops beating unexpectedly. Cardiac arrest is an “ELECTRICAL” problem.
Occurs when blood flow to the heart is blocked. A heart attack is a “CIRCULATION” problem
