Someone who has stopped breathing will die in 4 to 6 minutes. After even 2 or 3 minutes of not breathing he can have serious brain damage.
You never know how long someone has not been breathing.
Start Mouth-To-Mouth Breathing right away. Don't Wait!
Blowing air in is the best way to start breathing again. It gets more air into the lungs than other ways.
Here are the GET READY STEPS for Mouth-to-Mouth Breathing:
Step 1: Turn the head to the side. Clean out the Mouth using two fingers. Take out anything which can keep air going in.
Step 2: Put one hand on his forehead, and the other hand under his neck. Tip his head way back.
Step 3: Pinch his nose shut.
GET READY STEPS:
1. Clean the mouth
2. Tip the head
3. Pinch the nose
Take a deep breath, open your mouth wide, and put it over his mouth. Make a tight seal.
THE GO STEPS:
Step 1: BLOW to fill up his lungs. Watch his chest rise.
STEP 2: LISTEN for air to come out. Watch his chest fall.
Do the two steps over and over, once every 5 seconds. Do the GO STEPS until he starts to breathe for himself.
