| If you see someone drowning, speed is
very important. Once you get him out of the water, if he isn’t breathing, you
have four minutes before his brain is completely damaged. Support his neck, tilt
his chin upwards. This stops the tongue blocking the air way in the throat and
is sometimes enough to get him breathing again. If that doesn’t work, start
mouth-to-mouth breathing. Press his nostrils (鼻孔) together with your fingers.
Open your mouth wide and take a deep breath. Blow into his lungs until his chest
rises, and then remove your mouth and watch his chest fall. Repeat twelve times
a minute, keep going until professional help arrives. To bring a child back to life, keep your lips around its mouth and nose and gently blow into its mouth. Give the first four breaths as quickly as possible to fill the blood with oxygen.
