一、七选五
You should always seek professional medical help as soon as you are able to, but following correct first-aid steps can be the difference between life and death. Here are some suggestions about how to care for an unconscious（不省人事的）person.
Determine responsiveness. If a person is unconscious, try to awake him by gently touching his hands and feet or by speaking to him. 1
Check for breathing and a pulse. If the person is unconscious and unable to be awoken, check for breathing; look for a rise in the chest area. 2 Feel for air using the side of your face. If no signs of breathing are clear, check for a pulse.
If the person remains unresponsive, prepare for CPR（心肺复苏）. Useless you suspect a spinal（脊柱的）injury, carefully roll him onto his back and open his airway. 3 If the person begins to vomit, move him over to his side to help prevent choking.
4 Check these three things frequently as you give the person first-aid CPR.
●Airway. Does the person have a clear airway?
●Breathing. Is the person breathing?
●Circulation. Does the person show a pulse at major pulse point?
Make sure the person is warm as you wait for medical help. 5 However, if the person has heatstroke, do not cover him or keep him warm. Instead, try to cool him by fanning him and damping him.
A.Remember your ABCs of CPR.
B.Listen for the sound of air coming in and out.
C.Cover a towel or a blanket over the person if you have one.
D.The ABCs of CPR refer to the three critical things you need to look for.
E.Perform chest compression 30 times and rescue breathing twice as part of CPR.
F.If you suspect a spinal injury, leave the person where he is, provided he is breathing.
G.If he does not respond to any activity, sound, or touch, determine whether he is breathing.
