Understanding First Aid
What is First Aid?
First aid is the immediate care given to an injured or ill person with the aim of preventing the condition from worsening and promoting recovery. It can be as simple as stopping bleeding or as complex as performing CPR.
Importance of First Aid
- Prevent Further Injury: Immediate action can prevent an injury from becoming more severe.
- Save Lives: In some cases, first aid can be life-saving, especially in situations like cardiac arrest.
- Reduce Suffering: First aid can alleviate pain and suffering until professional medical help arrives.
Basic First Aid Principles
Assess the Situation
Before providing first aid, it’s crucial to assess the situation for any immediate dangers. This includes ensuring the scene is safe for both you and the injured person.
Call for Help
If the situation is life-threatening, call emergency services immediately. Provide them with clear information about the situation and the injuries sustained.
Care for the Injured Person
Once the scene is safe and you have called for help, follow these steps:
- Check Responsiveness: Tap the person’s shoulder and shout their name. Look for signs of consciousness, such as eye opening or verbal response.
- Check Breathing: Look, listen, and feel for normal breathing. If the person is not breathing or is only gasping, begin CPR immediately.
- Check for Bleeding: Look for signs of bleeding and apply pressure to stop it. Use a bandage or clean cloth if available.
- Stabilize Injuries: Use splints or slings to stabilize fractures or dislocations.
Common First Aid Situations
Bleeding
- Control Bleeding: Apply direct pressure to the wound with a clean cloth or bandage. Elevate the injured area if possible.
- Tourniquet: In severe cases, use a tourniquet to control bleeding above the injury. Apply it紧紧，但避免过紧，以免损伤神经。
Fractures and Dislocations
- Stabilize: Use splints or slings to stabilize the injured area.
- Do Not Move: Avoid moving the injured person or the injured part unless absolutely necessary.
Burns
- Cool the Burn: Run cool (not cold) water over the burn for 10-15 minutes.
- Protect the Burn: Cover the burn with a sterile, non-adhesive bandage or a clean cloth.
Choking
- Back blows: For a conscious person, give back blows between the shoulder blades.
- Abdominal thrusts: For a conscious person who cannot cough, perform abdominal thrusts.
- Heimlich Maneuver: For an unconscious person, perform the Heimlich maneuver.
Heat Exhaustion and Heat Stroke
- Cool the Body: Move the person to a shaded or air-conditioned area.
- Apply Cold Compresses: Use cool, wet cloths or ice packs to cool the body.
- Hydration: Provide water to drink if the person is conscious.
Advanced First Aid Techniques
CPR (Cardiopulmonary Resuscitation)
- Check Responsiveness: Ensure the person is unconscious.
- Check Breathing: Look, listen, and feel for normal breathing.
- Perform Chest Compressions: Place the heel of one hand on the center of the person’s chest. Place your other hand on top and interlock your fingers. Push down hard and fast at a rate of 100-120 compressions per minute.
- Give Breaths: After 30 compressions, give 2 rescue breaths.
Bandaging and Splinting
- Bandaging: Use a triangular bandage to apply pressure to a wound or to immobilize an injury.
- Splinting: Use a splint to immobilize a fractured or dislocated bone. Use padding to prevent pressure on the skin.
