2 breaths to 30 compressions
For an Adult, 2 person CPR is 30 compressions / 2 breaths. One person does the compressions, the other gives the breaths. To learn more about the correct steps for 2 person CPR (Adult, Child, Infant), take a CPR for the Professional Rescuer class.
30 compressions to 2 breaths. 2nd Answer: Perhaps not . . . the American Heart Association and the American Red Cross have approved and recommended the so-called "hands-only" CPR. You give chest compressions in the standard position, but you sort of bounce up and down on the patient's chest - perhaps 40 compressions or more per minute. You are doing it at the right rate if you are naturally bouncing up and down, like you would if you were giving chest compressions to a rubber ball. This method results in a good balance between doing the patient some good, while minimizing your fatigue. There are no breaths given in hands-only CPR.
Yes; if you are doing compressions breaths should be given as well.

Yes it's bad
Look in the mouth, sweep if you see the object; attempt to ventilate, 30 compressions if breaths don't go in; repeat sweep, breaths, compressions, until breaths go in.
You need to do 5 cycles of CPR in about 2 minutes. 2 breaths and 30 chest compressions constitutes a cycle. Chest compressions should be at a rate of about 100 compressions per minute - doing compressions in time to 'Nelly the Elephant' will be about the right speed.
One rescuer will give 30 compressions and the other rescuer will give 2 breaths. When the rescuer giving compressions gets tires and wants to change, on the last compression instead of saying 30 he/she says change. The 2 breaths are given, the rescuers stay on the same side of the patient, and move positions for the change. CPR then continues with the 30 compressions, then 2 breaths repeated until the next change is called for.
You could just do compressions at a speed of 100/minute, or you could do the 'mouth to mouth' part without the barrier. It all depends on you and how well you know the person. Either way, make sure EMS has been called!
These are the most recent PALS (Pediatric Advanced Life Support) Guidelines: When there is only one rescuer, which is often the case in CPR done outside the hospital, the chest compression to rescue breaths ratio is 30:2 (30 chest compressions, 2 breaths) just like it is for an adult. When there are two rescuers, as in, one person that can do compressions and one that can do breaths, the ratio changes to 15:2. In a hospital setting, when the infant or child is intubated (breathing tube down the throat), chest compressions are done continuously without interruption, while another provider at the same time gives rescue breaths with an ambu-bag down the breathing tube, at a rate of one breath every 6 to 8 seconds. This last method would only ever be done by health care providers.
It keeps the one doing compressions from wearing out and getting too tired.
