1. You resusci-breathing is being blocked by an obstruction in the airway. 2. The air you're breathing into the patient is not inflating the lungs but is going elsewhere (e.g. an esophageal tear dumping air into the chest cavity). 3. The chest is restricted from rising (seat belts if you're breathing someone in a wreck can sometimes do this). 4. You have not sufficiently hyperextended the airway. (see bockage above).
Re-position the head and try breaths again.

You are correct; 30 chest compressions and 2 rescue breaths.
If your are not trained in CPR or rescue breathing then you should not be giving rescue breaths as you can injure the victim. The lay rescuer should only provide compressions at a rate of 100 compressions per minute. AHA provides courses to learn CPR/ rescue breathing which are very beneficial.

Normal breathing
It isn't, and this is in fact incorrect.The correct procedure for infants and children is to start with 5 rescue breaths before chest compressions are even given. Once the 5 rescue breaths have been given the normal ratio of chest compressions to rescue breaths should be given (30/2).It should also be noted that the depth should be changed to a third of the depth of an adult for child and infant casualties. And of course child-1 hand, infant-2 fingers.
the guidelines for adults, children and infants is 30 chest compressions to 2 rescue breaths.
If the patient is not breathing, after giving 30 chest compressions or straight away in a child or someone who has drowned
You do not check for signs of circulation as a first aider, if they are not breathing then you perform 30 compresions at a rate of 100/minute followed by 2 rescue breaths regardless of whether they have signs of circulation (In a chilld you would also perform 5 rescue breaths before you start CPR). this is because even if they have circulation, if they're not breathing then they won't have circulation for long and CPR will do less harm than thinking there are signs of circulation when there aren't and not performing CPR.
