With the pace of life becoming faster and faster, in addition to the elderly, some young people are also suffering from sudden death. Life is always unexpected, learning first aid is urgent.
What is emergency care
Emergency treatment refers to when there is any accident or emergency, the rescuer before the arrival of medical care, according to the principle of medical care, use of on-site materials suitable for the initial rescue and care of the patient temporarily and appropriately, and then rushed to hospital. In the case of accidental injury, the most precious time in the process of self-rescue or rescue is the first 4 minutes, commonly known as the “golden 4 minutes”. By the time the ambulance arrives at the scene, many fresh lives have missed the best time for treatment, resulting in lifelong regret.
Emergency treatment is to highlight a “early” word. The “first witness on the spot” with first aid skills, by administering initial first aid to the victim, has the potential to alleviate the disability and suffering of the victim, and even save his life. When someone around you has an accident and needs your help, will you do it correctly? With the right knowledge of first aid, you may become the guardian of life someday.
What situations require emergency care
Cardiac arrest, foreign body in throat, broken bones, burns and scalds, gas poisoning, drowning, electric shock, mercury poisoning, bee stings… In the face of accidents, if the treatment is not appropriate, it is likely to cause secondary injuries, and even delay life saving. Among all first aid skills, CARDIopulmonary resuscitation is one of the most popular first aid skills to learn.
Cardiopulmonary resuscitation (CPR) and automatic external defibrillator (AED) are the most effective ways to prevent sudden cardiac arrest.
1. Identify and initiate first aid
The first step in CPR is to determine the patient’s consciousness by tapping the patient on the shoulder with both hands and calling the patient by the ear to see if there is a response. At the same time, seek help from people around, dial 120, and ask someone to help find the nearby AED. If the patient is not breathing or breathing abnormally, press the patient’s carotid artery with two or three fingers at the same time. If there is no pulse, the heart has stopped and cardiopulmonary resuscitation should be started immediately.
2. Press hard and fast on your chest 30 times
Lay the patient on a flat, hard surface with the head and torso on the same surface. Fold your hands, tilt your upper body forward, vertically down, and press hard and rhythmically at the junction of the patient’s nipples and sternum for 30 times, with a depth of 5-6 cm and a frequency of 100-120 times/min. If the patient is elderly, avoid excessive exertion that could damage bones or even further endanger internal organs.
3. Give two artificial breaths
First, place one hand on the patient’s forehead and press it down; Put your other hand on your chin and lift it up. Keep the line between your mouth and earlobe perpendicular to the ground. Foreign objects (such as dentures or vomitus) are then removed from the patient’s mouth. Finally, the patient’s nose is pinched, the mouth is wrapped around the patient’s mouth, and the gas is quickly blown in. Blow as much as you normally breathe.
4.Keep repeating steps 2 + 3
That’s 30 chest compressions and 2 mouth-to-mouth breaths. You may discontinue CPRCPR if the patient’s heartbeat, spontaneous breathing, and pulse are restored, and the patient is responding or groaning. Ineffective CPR: After CPR lasting more than 30 minutes, the patient’s breathing and pulsation do not return to normal, and the patient’s pupils are dilated and fixed.
What is an AED?
AED is a first-aid device, easy to operate, can be used for heart attack patients with electrical defibrillation, help patients with ventricular fibrillation to restore heart rhythm. Aeds are mainly located in large airports, high-speed rail stations, subway stations, convention centers and stadiums. At present, many marathons in China also arrange first responders with AED, and have successfully rescued people from cardiac arrest in critical moments. If an AED is available immediately, use the AED first before CPR.
The first scenario in which an AED is used must be a cardiac arrest.
In China, many people do not learn to use AED, but are afraid to use it. In fact, the AED is as simple as taking a photo with your phone. You just need to “listen to it, follow it” and operate according to voice prompts and screen displays.
Procedure for using AED:
1.Open: AED was placed on the left side of the patient. Press the power switch or open the monitor cover, the instrument will give voice instructions on the operation behind.
2.Paste: The electrode was pasted on the patient’s chest, one on the right upper chest wall (below the clavicle), the other on the lateral side of the nipple, and the upper margin was about 7cm from the axilla.
3.Insert: Insert the electrode plug into the AED host jack, and start analyzing heart rhythm, which takes 5-15 seconds.
4.electricity: ensure that no one contacts the patient, press the electrode button. Cardiopulmonary resuscitation (chest compressions and manual analysis) should be continued immediately after a defibrillation and repeated until paramedics arrive. If the analysis does not require defibrillation, continue CPR.
If there is no condition for artificial respiration or there is no AED on site, continuing cardiac compressions can also be effective. In addition to CPR, there are some other popular first aid skills that can be very useful in life.
Do not look up, nose bleed when looking up not only can not stop nosebleed, but will lead to nosebleed is inhaled into the mouth and respiratory tract; Hold both sides of the nose with fingers for 4 ~ 8 minutes, or use a cotton ball soaked in cold water to fill the nasal cavity compression hemostasis; The above methods still can not stop bleeding, should go to the hospital immediately.
Quickly leave the high temperature environment, move to a cool and ventilated place; Rest quietly, wet the body with cold water, drink some salty cool drinks; If it is serious, send it to the hospital immediately.
Bee stings should be carefully removed from the residual sting, gently squeeze the wound, squeeze out the venom, apply some ammonia or soda water; Wasp stings should be coated with acetic acid to neutralize the venom, and local cold compress to reduce swelling and pain; If nausea, dizziness and other abnormal reactions occur, you should go to the hospital immediately.
Foreign matter in the eye
First blink hard and frequently to flush the foreign object out with tears. If that doesn’t work, pinch your eyelids and rinse them under the tap. Never rub your eyes. Foreign bodies, no matter how small, can scratch your cornea and lead to infection. If a corrosive liquid gets into your eyes, you must seek immediate medical attention.
Hope that we learn more first aid skills, to love the people a safer world, in the face of danger can escape, save each other, protect the safety of life.
