If you see someone
drowning, speed is very important. Once you get him out of the 31
, if he isn't 32 , you have four minutes before his
brain is completely 33 . Support his neck, tilt (使翘起) his head
back and press his chin (下巴) upwards. This 34 the tongue blocking the airway in the
throat and is sometimes enough to get him breathing again. If that doesn't 35 , start mouth-to-mouth
breathing. Press his nostrils (鼻孔)
together with your 36 . Open your 37 wide and take a deep breath. Blow
into his lungs until his chest 38 . Then remove your mouth and watch his
chest fall. Repeat twelve times a minute. Keep doing 39
help arrives.
To bring a child back
to 40 keep your lips around his mouth and nose
and gently 41 his mouth. Give the first four
breaths as quickly as possible to
42 the blood with
oxygen. If, 43 your efforts, he starts turning a
blue grey colour, you can 44 no pulse (脉搏),then pressing is
the 45 chance of saving his
life.
With arms straight,
rock (摆动) forwards pressing down on the lower half of
the breastbones. Don't be too hard 46 you may break a rib (肋骨). Check
how effective you are seeing if his colour 47 or his pulse becomes independent
to your chest 48 . If this 49
, stop the pressing. Otherwise 50 until the rescue arrives.
