CPR is a must-have basic skill for modern people; familiar with it! You are the bodyguard of your friends and relatives around you.
Cardiopulmonary resuscitation, as its name implies, is a first-aid procedure performed in the case of breathing or heartbeat. The purpose is to save brain cells necrosis in the absence of oxygen as soon as possible (four minutes or more to start brain damage, more than ten minutes to cause irreversible damage to the brain), so the faster the rescue time, the better. Cardiopulmonary resuscitation is used in situations where heart attack, drowning, suffocation or other accidents cause coma and have a state of breathing and heartbeat.
1. Pat the patient's shoulder or press on the person, check the wounded unconscious, and pay attention to the patient without cervical spine injury, do not shake the patient violently.
2. Say loudly for help if the patient is unclear, call for help immediately; the instructions for help must be clear, for example: please call me an ambulance (outside the hospital) and yell at the duty doctor (in-hospital).
3. The rescue position is placed on the patient's shoulder and the rescuer is perpendicular to the patient's shoulder.
4. Open the patient's mouth and check for foreign matter in the respiratory tract.
5. Deviate the patient's head to one side and remove foreign objects such as chewing gum and dentures from the mouth and respiratory tract.
6. Press the pressure to keep the airway open, and prevent the tongue from clogging the airway due to gravity.
7. The cheek is close to the patient's nose, and the eyes are on the patient's chest for 3-5 seconds.
8. If there is no breathing, open the patient's mouth and pinch the patient's nose so as not to leak from the nose when blowing from the mouth.
9. Cover the patient's mouth, blow two breaths, each time blowing about 1.5-2 seconds, pay attention to the patient's chest with or without undulations, and wait for the patient's first breath to completely discharge and then blow the second mouth.
10. The index finger and middle finger first touch the larynx and slide outward to the groove formed by the ipsilateral trachea and neck muscles. Press and observe the carotid artery for 5-10 seconds. If there is a pulse, continue to perform artificial respiration until the patient returns to natural breathing, about 12-16 times per minute for adults.
11. If there is no pulse, prepare for chest cardiac massage.
12. Slide up along the lower edge of the rib to find the protruding end from the upper two fingers, and place the palm of the other hand to the massage position, taking care not to press the xiphoid.
13. Intertwin the two hands and lift the fingertips to avoid contact with the ribs.
14. The rescuer's arms are straight, perpendicular to the patient's body, and the shoulders are directly above the sternum, and quickly press down 4-5 cm (1.5-2 inches).
15. Single rescue artificial respiration: cardiac massage = 2:15, double rescue artificial respiration: cardiac massage = 1:5.
16. After completing four cycles, blow two breaths, check the pulse for 3-5 seconds; if there is no pulse, continue the heart massage, and then check every four cycles or 3-5 minutes.
17. If there is a pulse, check the breath for 3-5 seconds. If there is breathing and put the patient in a resuscitation position to avoid vomiting causing aspiration pneumonia, continue breathing if there is no breathing.
