CPR or cardiopulmonary resuscitation, is a life-saving technique that's used when someone's breathing or heart has stopped. It combines chest compressions and, in traditional CPR, rescue breaths to help circulate blood and oxygen to vital organs until emergency medical services arrive.
Here's a breakdown of what CPR is and how it's performed:
What is CPR?
CPR is an emergency procedure that attempts to manually preserve intact brain function until further measures are taken to restore spontaneous circulation and breathing in a person who is in cardiac arrest.
Cardiac arrest can occur due to various reasons, including heart attack, drowning, or electric shock.
CPR aims to keep oxygenated blood flowing to the brain and other vital organs, increasing the chances of survival.
How CPR is Performed:
The American Heart Association emphasizes the importance of chest compressions. Here's a general guide:
1. Assess the Situation:
Check for responsiveness: Gently shake the person and shout, "Are you OK?"
If the person is unresponsive, call 911 (or your local emergency number) immediately.
If possible, have someone else retrieve an automated external defibrillator (AED).
2. Chest Compressions:
Place the person on their back on a firm surface.
Kneel beside the person's chest.
Place the heel of one hand in the center of the person's chest (lower half of the breastbone).
Place your other hand on top of the first hand and interlock your fingers.
Position your body so that your shoulders are directly above your hands.
Push straight down on the chest, compressing it at a depth of at least 2 inches (5 centimeters) for adults.
Perform compressions at a rate of 100 to 120 compressions per minute.
Allow the chest to recoil (return to its original position) completely after each compression.
3. Airway (If trained):
After 30 chest compressions, open the person's airway using the head-tilt, chin-lift maneuver.
Place one hand on the person's forehead and gently tilt their head back.
Place the fingers of your other hand under the person's chin and gently lift it upward.
4. Breathing (If trained):
Pinch the person's nose closed.
Seal your mouth tightly over the person's mouth.
Give two rescue breaths, each lasting about one second, and watch for the chest to rise.
Return to chest compressions.
5. Continue CPR:
Continue cycles of 30 chest compressions and two rescue breaths (if trained) until:
Emergency medical services arrive and take over.
An AED is available and ready to use.
The person shows signs of life, such as moving or breathing.
You are too exhausted to continue.
Hands-Only CPR:
If you are not trained in traditional CPR or are uncomfortable giving rescue breaths, you can perform hands-only CPR.
Hands-only CPR involves continuous chest compressions at a rate of 100 to 120 compressions per minute.
This method is effective in many cases, especially for adults who have suddenly collapsed.
Important Notes:
CPR is most effective when performed immediately after cardiac arrest.
Proper training is essential for performing CPR correctly.
AEDs can significantly increase the chances of survival during cardiac arrest.
Always prioritize calling emergency services.
