Whether or not the person is breathing. If the chest rises, they are. If it doesn't, start mouth to mouth.
Chest rises in CPR during breaths of about 2 inches.
During CPR, the chest compressions are applied; during rescue breathing there are no chest compressions used.
usually if there isnt anything obstructing the airway
Give enough air to make the chest rise 1 - 1 1/2 inches.

If while recieving breaths during CPR their chest does not rise. That means the air is not able to reach their lungs.
As you give the breaths, look down at the infant's chest and you should see it rise 1/2 to 1 inches.
During hands-only CPR, it is recommended to perform chest compressions at a rate of 100 to 120 compressions per minute.
1/2 inch
For an 8-year-old during CPR, the recommended ratio is 1 rescue breath for every 30 chest compressions if you are performing hands-only CPR. If you are performing CPR with rescue breaths, the ratio is 2 rescue breaths followed by 30 compressions. Each rescue breath should last about 1 second and make the chest rise visibly. Always ensure that the airway is clear before delivering breaths.
