C.P.R., or Cardio-Pulmonary Resuscitation means to artificially
breath and circulate blood for a person with no heartbeat
or respiration. When complications in the body have caused
the body to stop breathing and the heart to stop pumping,
oxygen is not readily transported throughout the body to
the vital organs. When the cells of these organs are oxygen
depleted for too long, they begin to die and eventually
cause death. This is known as cardiac arrest.
Causes for cardiac arrest include, but are not limited
to: heart attack, metabolic problems, drowning, electrocution,
respiratory problems, severe trauma and narcotic use.
C.P.R.-trained personnel deliver mouth-to-mouth resuscitation
and chest compressions to the person in cardiac arrest,
although CPR does not restart the heart. It is simply a
technique that will "buy some time" until a defibrillator
and advanced medical care arrives.
In most cases, before the heart completely stops, it goes
into a disorganized electrical rhythm called Ventricular
Fibrillation or Ventricular Tachycardia. In this case, the
heart pumps an insufficient volume of blood to sustain human
life. When this occurs, early defibrillation is key. Defibrillation
trained personnel attach electrode pads to the person and
deliver a shock with the intent of correcting the disorganized
electrical rhythm.
The Cardiac Arrest "Chain of
Survival"
Early Access: When a problem
is recognized and 9-1-1 is activated.
Early CPR: Trained personnel
perform CPR.
Early Defibrillation: Trained
personnel perform defibrillation.
Early Advanced Care: Airway
management and drug therapy performed by advanced medical
care professionals.
