CPR

Physicians believe many deaths can be prevented with proper use of CPR, or cardiopul-monary resuscitation. （心肺复苏技术） The rescuer (救助者) should first check for signs of breathing and pulse (脉搏), if neither is present, have someone phone for help. Meanwhile the rescuer should position the victim (受害人,发病人) on the back, turn the victim's head to the side, and remove any form of objects from airway. Then tilt (使倾斜) the victim's head back, pinch (掐，捏) the victim's nostrils (鼻孔) closed, and inhale (吸气) deeply, and place the rescuer's mouth over the victim's to form a tight sill (基石,门槛). The rescuer should exhale twice slowly into the victim's mouth until the chest (胸膛) rises. The rescuer should bend with arms held straight up and down, press 15 times on the middle of the victim's chest. Alternating (交替, 轮流) this compression with mouth to mouth resuscitation (人工呼吸) for 9 to 11 seconds or until breathing resumes (恢复). After completing four cycles of CPR, the rescuer should check for any signs of breathing and pulse. If there is pulse no breathing, continue rescue breathing. If the victim has neither pulse nor breathing, continue CPR as necessary.
