A breathing barrier device should be used if providing rescue breathing to minimize the risk of disease transmission.
8-10 breaths/min for adults12-20 breaths/min for pediatrics
Tilt the head back to open the airway and look, listen, and feel for breathing; look for the chest to rise and fall, listen for the breaths, and feel for the breaths on your cheek. If you determine the person is not breathing, give 2 breaths and start CPR.
Check for adequate breathing for 10 seconds; the chest should clearly rise for breathing to be effective.
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.
