The four major techniques of trauma first aid are hemostasis, bandaging, immobilization, and handling.
Trauma first aid three first three principles
1, if the casualty suffocates, heartbeat and respiration has just stopped, must not be moved, must be resuscitated first, and then carried.
2, if the injured patient bleeding situation, to stop bleeding first, after carrying.
3, if you find a fracture of the patient, we must first help the patient for immobilization, and then carry.
To learn to judge the patient's injuries, the following is a list of some common injuries to determine the method:
Confusion, depression; shallow breathing, extremely slow, irregular or stop; heart rate or heart rhythm is significantly tachycardia, bradycardia, irregular heartbeat or cardiac arrest; blood pressure is significantly elevated, severely lowered or can not be measured; building The aperture is dilated or narrowed, unequal in size on both sides, and the reflex to light is dull or absent.
General principles of first aid
First determine whether the casualty is in further danger; calm, cool, and quickly give priority to emergency treatment of critically ill patients; for respiratory and cardiac failure or cessation of the patient, should be cleaned up respiratory tract, and immediately give artificial respiration or chest cardiac compression; to control bleeding; to consider whether there is a possibility of poisoning;
The principles of first aid for trauma are as follows:
1, establish a holistic awareness: a comprehensive understanding of the injuries, to avoid omissions;
2, first save life: such as respiratory cardiac arrest, the first to carry out cardio-pulmonary resuscitation;
3, check the injuries and fast and effective hemostasis: by compression, stuffing, bandage, tourniquet and other ways to stop bleeding;
4, pay attention to the order of bandaging: first bandage the head, chest, then the abdomen, and finally the limbs;
5, pay attention to the order of immobilization: first fix the neck, then fix the limbs;
6, the operation of the rapid and accurate: the action should be light, to prevent the injury from aggravation;
7, wear personal protective equipment: wear medical gloves, or with a gauze, dry towels, handkerchiefs, plastic bags and other alternatives.
