There is no substitute for learning cardiopulmonary resuscitation (CPR), but
emergencies don't wait for training. These instructions are for conventional
adult CPR. If you've never been trained in CPR and the victim collapsed in front
of you, use hands-only CPR.
For children, use the following guidelines:
These are the steps to perform adult CPR:
CPR is easy but needs to start as soon as possible after someone stops
1. Attempt to wake the victim
- If the victim is not breathing (or is gasping for air),
call 911 immediately and go to step 2.
- If someone else is there to help, one person should call 911
while the other moves on to step 2.
- If the victim is breathing, see the Tips section at the
bottom of this page for what to do.
2. Begin chest compressions
- The heel of one hand should be placed in the middle of the
- The other hand should be placed on top of the first with
your fingers interlaced.
- Compress the chest at least 2 inches (4-5 cm). Allow the
chest to completely recoil before the next compression.
- Compress the chest at a rate of at least 100 pushes per
minute. Perform 30 compressions at this rate (should take approximately 18 seconds).
- If you are not trained in CPR, continue to do chest
compressions until help arrives or the victim wakes up.
- It's normal to feel pops and snaps when you first begin
chest compressions - DON'T STOP! You're not going to make the victim worse.
3. Pump - 100 compressions per minute; depth 2 inches
4. Begin rescue breathing
- If you have been trained in CPR, after 30 compressions,
open the victim's airway using the head-tilt, chin-lift method.
- Pinch the victim's nose and 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, and then repeat the rescue breath once more.
- If the chest does not rise on the first breath, reposition
the head and try again.
- Whether it works on the second try or not, go to step 4
- If you do not feel comfortable with this step, just
continue to do chest compressions at a rate of 100/minute.
Repeat chest compressions
- Do 30 more chest compressions
just like you did the first time.
Repeat rescue breaths
- Give 2 more breaths just like you
did in step 3 (unless you are skipping the rescue breaths).
Repeat steps 3 and 4 for about 2 minutes (approximately 5
cycles of 30 compressions and 2
- If you have access to an automated external defibrillator
(AED), continue to do CPR until you can attach it to the victim and turn it on.
- If you saw the victim collapse, put the AED on right away.
If not, attach it after approximately one minute of CPR (chest compressions and rescue breaths).
- After 2 minutes of chest compressions and rescue breaths,
stop compressions and recheck victim for breathing.
- If the victim is still not breathing, continue CPR
starting with chest compressions.
- Repeat the process, checking for breathing every 2 minutes
(approximately 5 cycles), until help arrives.
- If the victim wakes up, you can stop CPR, but still make
sure 911 has been called.
- Chest compressions are extremely important. If you are not
comfortable giving rescue breaths, still perform chest compressions. It's called
- If the victim is breathing, briskly rub your knuckles
against the victim's sternum. If the victim does not wake, call 911. If the
victim wakes up, but is confused or not able to speak, call 911.
- This information is not a substitute for actual CPR
training. Find a CPR class and get proper training. Not every CPR class is the
same. There are CPR classes for healthcare professionals as well as
CPR classes for the layperson.
