Definition: First Aid
The immediate and temporary care given to an injured or ill person before proper medical treatment is called first aid.
Basic Principles of First Aid
Life and Resuscitation: ABC
1. Airway
If the victim has difficulty breathing, ensure their airway is clear. Gently tilt the head backward and lift the chin upward to open the respiratory passage. This position prevents the tongue from blocking the airway, allowing smooth airflow.
2. Breathing
If the victim has stopped breathing, provide mouth-to-mouth resuscitation. Pinch the victim's nose shut, take a deep breath, and seal your mouth over the victim's mouth. Blow air into the lungs until the chest rises, then allow the chest to fall naturally. Repeat this process every 4–5 seconds until normal breathing resumes or professional help arrives.
3. Circulation
If the victim is unconscious and has no pulse, perform cardiopulmonary resuscitation (CPR). Start by giving two mouth-to-mouth breaths. Place both palms one over the other in the centre of the chest (just above the sternum). Press down firmly and quickly, compressing the chest about 2 inches deep. Repeat chest compressions about 15 times at a steady rhythm (around 100-120 compressions per minute). Alternate between 2 breaths and 15 chest compressions until help arrives or the person shows signs of recovery.
Simple Steps for Providing First Aid in Different Situations:
1. External Bleeding: If a person is bleeding, the first step is to help them sit or lie down comfortably. Keep the bleeding part of the body elevated (above the heart level) to reduce blood flow. Clean the wound with clean water and apply pressure with a clean cloth to stop the bleeding.
2. Burns and Scalds
Minor Burns:
- Wash the burn with cool water or hold it under running water to reduce the heat.
- Give the person water to drink to keep them hydrated.
- Clean the burn with a cotton swab soaked in an antiseptic solution.
- Do not apply oily ointments like ghee or butter to the burn. Cover the burn with a clean, dry cloth or dressing.
Serious Burns:
- Give the person emotional support to keep them calm. Cover the burn with a sterilised cloth or clean fabric.
- Remove jewellery or shoes if it can be done easily without hurting the burn.
- Do not burst blisters or touch the burnt skin. Do not apply oily ointments or try to remove any cloth stuck to the burn.
- If the person is conscious, give them water to drink, but avoid tea or coffee.
- Get medical help immediately.

Immediate steps for burns
3. Sunstroke: Sunstroke occurs when someone has been in the sun for too long and their body loses water and minerals.
Remedial Measures:
- Take the person to a cool place or the shade.
- Sponge their body with cold water to cool them down.
- Put a cold cloth on their neck to reduce their body temperature.
- Give them plenty of water or liquids like sherbet to drink.
- If the person feels like vomiting, make them lie on their stomach with their head turned to one side.
- Get medical help or take the person to a hospital.

4. Snakebite: There are about 2000 species of snakes, but only a few, like cobras, kraits, vipers, and sea snakes, are poisonous. Not all snakebites are deadly, but the fear of the bite can cause a lot of stress.
Remedial Measures:
- Wash the wound with clean water.
- Give the person emotional support to calm them down.
- Tie a cloth tightly above the bite to slow the spread of venom.
- Get immediate medical help for treatment.
5. Dog Bite: A dog bite can cause infection, so it’s important to give first aid and seek medical help.
Remedial Measures:
- Wash the wound with an antiseptic solution like potassium permanganate.
- Cover the wound with a clean, dry cloth.
- Get medical help immediately and make sure the person receives an anti-rabies vaccine to prevent infection.
