The correct way to perform CPR

What is CPR? Using manual techniques, mouth-to-mouth resuscitation and chest compressions are performed on people who have suffered sudden cardiac death, in order to bring those who are near death or already dead back to life. What are the eight steps of CPR? (1) Assessing consciousness: Call out to the person who has fallen and shake them: “Hey, what’s wrong?” ”Check for sensation. (2) Emergency call for help: Shout for assistance or make a phone call to the monitoring room at 6872521 or to the plant’s on-duty staff. (3) Position the body correctly: Having the face facing down makes rescue difficult; the body should be turned as a whole, with the head, shoulders, and torso moving together to put the person in a supine position. (4) Opening the airway a) Head-tilt method: The rescuer kneels on one side of the patient’s head, places one hand behind the patient’s neck to lift it, and uses the other hand to press on the forehead and tilt it backward. b) Head-tilt and chin-lift method: Place one hand on the forehead to tilt the head back, and use the index and middle fingers of the other hand to place under the jawbone near the chin in order to lift it. c) Jaw thrust method: The rescuer uses both hands to grasp and lift the patient’s mandibular angles on both sides, pushing the jaw forward. (5) Assessing breathing: observe, listen, and feel. (6) Artificial exhalation: The rescuer covers the patient’s nostrils with their hand, takes a deep breath, opens their mouth wide, covers it over the patient’s mouth, and blows air in. (7) Checking for a pulse: Use the carotid artery examination method – the rescuer uses their fingers to feel the patient’s Adam’s apple and moves them left and right to the deep groove, where the carotid artery can be felt. (8) Chest compressions: a) Determine the compression site: The rescuer uses the index finger and middle finger to move upward along the lower edge of the rib cage on one side of the patient to the sternal notch; the middle finger is placed in this notch, while the index finger and middle finger are placed side by side at the lower end of the sternum. Then press the base of the other hand’s palm against the index finger. The long axis of the base of the palm should be parallel to the long axis of the sternum, with the palms of the fingers raised so as not to touch the chest wall at all. Finally, place the right palm on top of the left palm with the fingers interlaced. b) Body posture: The rescuer’s arms should be straight, with the shoulders positioned directly above the patient’s sternum. To save effort, the upper body should lean forward; using the weight of the upper body as well as the strength of the shoulder and arm muscles, the sternum should be pressed vertically downward, with a compression depth of 4–5 centimeters. C) Pulsing frequency: 60-80 times per minute. How many types are there of cardiopulmonary resuscitation techniques? How to operate it? 　　 (1) Single-person rescue method ； a) Compression frequency: 80 times per minute b) Artificial ventilation frequency: 12 times per minute c) Ratio of compression to ventilation: 15:2. (2) Two-person resuscitation method; a) Compression frequency: 60 times per minute; b) Artificial ventilation frequency: 12 times per minute. c) The ratio of compression to blowing is 5:1.
