First aid is the initial medical actions and treatments given to an injured or sick person in case of injury, illness or head donation. The main goal of first aid is to preserve life, prevent further injuries, and assist in quick recovery and return to normal activity.

First aid actions can include the following basic actions:

1. Safety check: assessing the situation before approaching and understanding the risks, including those that you can help with and not those that can harm you.

2. Call for help: alert the professional groups in case you are unable to treat the injured person alone or if the situation is very serious.

3. Removal of risks: removal of risks around the injured, such as fire, dangerous chemicals or any other risk that can cause further damage.

4. Testing vital functions: testing the cardiac and respiratory activity of the injured (pulse test and breathing recovery). If required, RCP (cardiopulmonary resuscitation) can be performed.

5. Stopping bleeding: When there is bleeding, the injured can damage the blood and life if actions are not taken to stop the bleeding.

6. Irrigation of fluids: in cases where the injured person feels hostile or has lost fluids, it should be considered offering him to drink fluids to avoid the risk of dehydration and bleeding.

7. Motor functions: the proper dose for paramedical purposes can affect the functions that lead to action, therefore in some cases it is possible to give a complimentary clinical dose.

8. Heat maintenance: while maintaining heat in the injured, especially if there is a risk of mixing.

First aid is a key skill in the world of medicine and the military, and it can be the difference between life and death in many cases. Professional training and in-depth knowledge can save lives and prevent serious injuries.
