Every 5 seconds
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.
In CPR, if the airway is open and the patient was given rescue breaths and the air is not going in, there may be something lodged in the patients throat, and the Heimlich maneuver should be performed.

Every 2 minutes check for signs of life when performing RB.
About how often should you stop and check for signs of life when performing rescue breathing on a child?
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.
Rescue breaths are typically a full second in length.
If after the head is tipped for 10s, and there is no breathing (adult), give 2 breaths and immediately begin CPR.
If the patient is choking, the first priority is to clear the airway, not check the pulse. The airway should be cleared first, and then once the rescue breaths go in, check for a pulse.
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).
