how to perform cpr
Time Required: CPR should start as soon as possible
Here's How:
1. Stay Safe! The worst thing a rescuer can do is become another victim. Follow universal precautions and wear personal protective equipment if you have it. Use common sense and stay away from potential hazards.
2. Attempt to wake victim. Briskly rub your knuckles against the victim's sternum. If the victim does not wake, call 911 and proceed to step 3. If the victim wakes, moans, or moves, then CPR is not necessary at this time. Call 911 if the victim is confused or not able to speak.
3. Begin rescue breathing. Open the victim's airway using the head-tilt, chin-lift method. Put your ear to the victim's open mouth:
* look for chest movement
* listen for air flowing through the mouth or nose
* feel for air on your cheek
If there is no breathing, pinch the victim's nose; make a seal over the victim's mouth with yours. Use a CPR mask if available. Give the victim a breath big enough to make the chest rise. Let the chest fall, then repeat the rescue breath once more.
4. Begin chest compressions. Place the heel of your hand in the middle of the victim's chest. Put your other hand on top of the first with your fingers interlaced. Compress the chest about 1-1/2 to 2 inches (4-5 cm). Allow the chest to completely recoil before the next compression. Compress the chest at a rate equal to 100/minute. Perform 30 compressions at this rate.
5. Repeat rescue breaths. Open the airway with head-tilt, chin-lift again. This time, go directly to rescue breaths without checking for breathing again. Give one breath, making sure the chest rises and falls, then give another.
6. Perform 30 more chest compressions. Repeat steps 5 and 6 for about two minutes.
7. Stop compressions and recheck victim for breathing. If the victim is not breathing, continue chest compressions and rescue breaths.
8. Keep going until help arrives.
