What are the basic knowledge of first aid

Whether at work, in daily life or outside, there will be special crisis situations, such as when someone suddenly has an emergency attack or you encounter a special dangerous situation. You need to understand some basic knowledge of first aid. Many people do not know first aid knowledge and are helpless when their relatives or friends are in trouble. When they encounter dangerous situations, they can only wait for rescue from others. So it is necessary for us to learn some basic knowledge of first aid. Let me introduce it below.

1. First aid for ankle sprain

1. For mild ankle sprain, you should first apply cold compress to the affected area, then switch to hot compress after 24 hours, wrap the ankle with a bandage and raise the foot to relieve the symptoms.

2. First aid for electric shock

① Cut off the power supply immediately.

② If you cannot find the gate, you can use insulating materials to pry open the wires or cut them.

③Immediately lift the person who has been electrocuted to a ventilated place, unbutton his clothes and belt. If he stops breathing, perform mouth-to-mouth artificial respiration or send him to a nearby hospital for emergency treatment.

④ You can use saline or vaseline gauze to bandage the local burn area.

3. First aid for arterial bleeding

① If there is bleeding in a small artery and the wound is not large, you can apply sterilized cotton on the wound and apply pressure bandage, which can usually stop the dizziness.

② When bleeding does not stop, you can elevate the injured limb to slow down the blood flow and help stop the dizziness.

③ When the bleeding in the limbs is severe, a tourniquet can be tied on the upper end of the wound. A towel or cloth should be placed before tying, and then it must be loosened once every half an hour. The total binding time should not exceed two hours to avoid ischemia and necrosis of the limbs. After initial treatment, the patient should be sent to hospital for treatment immediately.

After reading the basic knowledge of first aid that I introduced above, have you learned any tricks that you find particularly practical? In fact, many times, whether you or your loved ones are in danger of death, as long as you know certain first aid methods, you may be able to escape the clutches of death. Don't wait until then to regret not having learned some knowledge in this area. Some basic first aid measures should be essential skills for each of us.
