Answer:
Give 1 rescue breath about every 5 seconds
Explanation:
Since the unconscious adult has a pulse, but is not breathing, the first thing to do in such case is to give rescue breath every 5 to 6 seconds, which means that in a minute you should have given 10 to 12 rescue breaths. Ensure that you check for a pulse every two minute while you wait for the EMS personnel. In the event that there is no pulse, then chest compressions as well as ventilations should be administered at the rate of 30:2.
