Some first aid methods may not be used for a lifetime, but if they are not used, they may be the price of their lives.
According to authoritative statistics, the penetration rate of first aid skills in our country is only 1%, while in Europe and the United States, it can reach 70% to 80%, and the neighboring Japan can reach a staggering 92% of middle school students alone. It can be seen that our first aid popularization work has a long way to go, so today Xiao Tang takes you into the field of medical and health first aid, so that you can easily learn some commonly used first aid common sense.
Cardiopulmonary resuscitation
1. The importance of CPR
(1). CPR is the most commonly used first aid skill in clinical and outdoor first aid, which is convenient and effective, and can pull people back from the death line. For some diseases caused by cardiac arrest has an irreplaceable effect. Especially in the absence of rescue drugs and items outdoors, it is the only first aid measure that can open a green channel for life.
(2). Sudden death, myocardial infarction, arrhythmias and other diseases can lead to the stop of the heart, and after the heart stops beating, it will stop the blood supply to the brain, resulting in cerebral ischemia and hypoxia. Brain cells in a state of ischemia and hypoxia for 2 minutes can stop brain electrical activity, 4-6 minutes will appear irreversible damage, resulting in brain cell necrosis. Effective CPR must be given at this time to avoid brain damage that leads to brain death. So how important CPR is.
2. Evaluation and operation methods of cardiopulmonary resuscitation
(1). If you are indoors, you should lie the patient flat on the ground, and if you are outdoors, you must first ensure the safety of the surrounding environment to avoid secondary accidents.
(2) Judge the patient's consciousness: pat the patient's shoulder and shout in the ear to see if the patient responds
(3) Judge vital signs: whether the patient's chest is undulating and observe whether there is breathing, while implanting and forefinger to touch whether the carotid artery is pulsating (the carotid artery is opened about two fingers next to the human laryngeal junction). These actions must be done quickly, and if none of the above signs are present, CPR should be performed immediately.
(4). Chest compression: The position selected when pressing must be a flat and hard plane to avoid insufficient depth when pressing. Place the patient face up flat on the ground and flatten the limbs. Then the rescuer kneels next to the patient to find the right position to start pressing (the specific position is the midpoint of the connection between the two nipples) The hands are crossed and overlapped, the palm root of the left hand is placed in the patient's pressing position, the five fingers of the left hand are upturned, and the arms must be straight, at a 90° angle with the patient's body. Start pressing at a speed of 100 to 120 times per minute and a depth of 5-6 cm. The palm root of the press cannot leave the body.
(5). Open airway: Check whether there is any secretion in the patient's mouth and nasal cavity, and if there are some, it should be cleaned up in time, and if there are dentures, it should be removed. The patient's jaw is then lifted with the right hand, the left hand side palm presses on the forehead and pinches the patient's nose (clinically called the upward jaw lifting method) to ensure that the patient is on the back of the head and the nostrils are facing up.
(6). Artificial respiration: mouth-to-mouth blowing, using the above-mentioned upward jaw lifting method, continuously blowing twice, each blowing for 1-2 seconds. After each blow, observe whether the patient's chest is undulating.
(7). Press 100-120 times per minute, then blow twice for a cycle. Until the arrival of a health care worker or the patient's heart returns to beating.
The above is the CPR first aid method shared by Xiao Tang, and there are many commonly used first aid measures, such as Heimlich first aid, how to deal with acute myocardial infarction, etc. Next time share Heimlich first aid. Thank you for reading, I hope you will never use these methods, but you must, because emergency moments can save lives.
