9、ly and safely. If a person collapses and stops breathing, begin the ABCs of CPR. Do not go beyond A (airway clearance) if breathing resumes.

14、se as you exhale or fall when you pause, the airway may still be obstructed. Bend the neck back farther and lift the chin higher. (Do not bend an infants neck too far back or the airway will close.) If no obstruction is found, roll the victim on his side toward you and deliver four firm slaps betwee
15、n the shoulder blades. Then place the victim on his back again, put your fist just above the navel, and forcefully but carefully push once. These movements combined may force air out of the lungs and remove any object trapped deeper in the airway. 3. After assuring an open airway, check for a pulse
16、by placing your thumb and middle finger on the neck on either side of the windpipe. If there is a pulse, resume the inhalations anal exhalations at the rate of one cycle every five seconds, or 12 a minute. Use shallower breaths for children, about 20 a minute.

20、cked, correct your position and proceed cautiously. 5. Chest compression must be matched with mouth-to-mouth breathing. If there are two rescuers, one should give the mouth-to-mouth respiration at the rate of one exhalation for every five compressions. If you have no help, give two exhalations after
21、 every 15 compressions at the compression rate of about 80 per minute. For small children the compression rate should be higher, about 100 to 125 a minute. 6.
