Here's what you need to know about first aid:

First aid for arterial hemorrhage.

Arteriole bleeding, the wound is not large, can be applied to the wound with sterilized cotton, pressure bandaging, generally can stop dizziness.

If the bleeding does not stop, the injured limb can be elevated to slow down the blood flow and help relieve the dizziness.

When the bleeding of the limbs is severe, the tourniquet can be tied to the upper end of the wound, and a towel or cloth should be padded before the bandage, and then it must be relaxed once every half an hour, and the binding time should not exceed two hours in total, so as to avoid ischemia and necrosis of the limbs. After initial treatment, they should be sent to hospital for treatment immediately.

Fracture First Aid Method:

Hemostasis: Acupressure, bandaging, tourniquet and other methods can be used to stop dizziness.

Bandaging: Open fractures are compressed and bandaged with sterile gauze, and the exposed bone ends cannot be returned.

Fixation: The splint is padded with soft objects such as old clothes, and wooden sticks can also be used as substitutes to fix the upper and lower joints of the injured limb when there is no splint.

**: If conditions permit, you can send it to the hospital after debridement and pain relief**.

First aid for spinal bone injuries:

Patients with spinal bone injury can be asked to move their limbs if they are clear-headed, and the simple movement of both lower limbs is impaired, indicating that the thoracic or lumbar spine has been severely injured; If the upper limbs are also immobile, the cervical spine is also damaged. First, the patient is placed on the ground with both upper limbs straight together. Put the door panel next to the patient, 4 movers squat on the side of the patient, one person supports his back and waist, one person supports his shoulder blades, one person supports his buttocks and lower limbs, one person supports his head, and keeps his head on the same axis at any time, 4 people at the same time, slowly roll the patient to the door panel, make him lie on his back, put a small pillow on the waist and back of the neck, put soft pillows on both sides of the head, fix the head with cloth strips, and then rush to the nearest hospital.
