First Aid

First Aid

First Aid is the immediate and temporary care given to a person who has been injured or suddenly taken ill before professional medical help arrives. The main purpose of first aid is to preserve life, prevent the condition from worsening, and promote recovery. It is often provided at the scene of an accident or emergency and can make a vital difference between life and death.

First aid involves simple, practical medical techniques that anyone can learn. It includes actions like stopping bleeding, performing cardiopulmonary resuscitation (CPR), treating burns, managing fractures, and ensuring the victim’s safety and comfort. Being trained in first aid empowers individuals to respond quickly and effectively during emergencies.

The basic principles of first aid are often summarized as the “3 Ps”:

1. Preserve Life – Protect the casualty from further harm and provide basic life support.

2. Prevent Further Injury – Take steps to stop the condition from getting worse (e.g., controlling bleeding, keeping the person still).

3. Promote Recovery – Provide reassurance and comfort, and assist in the healing process until professional help is available.

First aid also emphasizes safety — both for the rescuer and the casualty. Before helping someone, it’s important to check the scene for potential dangers such as fire, traffic, or electricity.

In everyday life, accidents and medical emergencies can happen at any time — at home, school, workplace, or on the road. Therefore, having basic first aid knowledge is essential for everyone. It helps save lives, reduces the severity of injuries, and ensures timely medical assistance.

Basic Life Support (BLS) and CPR (Cardiopulmonary Resuscitation)

Basic Life Support (BLS) refers to the immediate medical care provided to a person experiencing life-threatening conditions such as cardiac arrest, respiratory failure, or airway obstruction. Its main goal is to maintain the circulation of oxygenated blood to vital organs, especially the brain and heart, until advanced medical help arrives. BLS can be performed by trained individuals, including healthcare providers, first responders, and even bystanders with basic training.

BLS includes three essential components known as the “ABCs” of life support:

1. A – Airway: Ensure that the person’s airway is clear of any obstruction. Tilt the head back and lift the chin to open the airway.

2. B – Breathing: Check for normal breathing for about 10 seconds. If the person isn’t breathing, give rescue breaths.

3. C – Circulation: If there is no pulse, start chest compressions to restore blood flow.

Cardiopulmonary Resuscitation (CPR)

CPR is a vital part of Basic Life Support. It is a combination of chest compressions and rescue breaths used when a person’s heart has stopped beating or they have stopped breathing. The main goal is to maintain blood circulation and oxygen flow to the brain and other organs until professional help is available.

Steps for Performing CPR (for adults):

1. Check responsiveness – Tap the person and shout to see if they respond.

2. Call for help – Dial emergency services immediately or ask someone else to do so.

3. Check breathing and pulse – If absent, start CPR right away.

4. Chest compressions – Place hands in the center of the chest and press down hard and fast (about 5–6 cm deep, at a rate of 100–120 compressions per minute).

5. Rescue breaths – After 30 compressions, give 2 rescue breaths (mouth-to-mouth), making sure the chest rises.

6. Repeat – Continue the cycle of 30 compressions and 2 breaths until professional help arrives or the person starts breathing.

Importance of BLS and CPR:

• Helps preserve life in cardiac or respiratory emergencies.

• Maintains blood and oxygen circulation to vital organs.

• Increases the chances of survival until medical professionals take over.

• Can be performed anywhere — at home, school, or workplace — by trained individuals.

Wounds and Bleeding

Introduction:
A wound is an injury that causes a break or damage to the surface of the skin or underlying tissues. It can occur due to accidents, cuts, burns, or impacts. Wounds may range from minor scratches to deep injuries that damage muscles, nerves, or bones. Bleeding (also called hemorrhage) happens when blood escapes from damaged blood vessels due to injury. Proper management of wounds and bleeding is crucial to prevent infection, excessive blood loss, and shock.

Types of Wounds:

1. Incised Wound – Caused by sharp objects like knives or glass; edges are clean and may bleed heavily.

2. Lacerated Wound – Caused by blunt trauma; edges are irregular and tissues are torn.

3. Puncture Wound – Caused by pointed objects such as nails or needles; bleeding may be minimal but infection risk is high.

4. Abrasion – A superficial wound caused by friction, such as scraping the skin on a rough surface.

5. Contusion (Bruise) – Caused by blunt impact leading to internal bleeding under the skin without surface breakage.

6. Avulsion – A portion of tissue is torn away from the body.

7. Gunshot or Crush Wound – Caused by bullets or heavy objects; often complex and severe.

---

Types of Bleeding:

1. Arterial Bleeding – Bright red blood that spurts with each heartbeat; most dangerous and difficult to control.

2. Venous Bleeding – Dark red blood that flows steadily; easier to control but can still be life-threatening.

3. Capillary Bleeding – Slow, oozing bleeding from small blood vessels; usually minor.

---

First Aid for Wounds and Bleeding:

1. Ensure safety – Check surroundings before providing help.

2. Apply direct pressure – Use a clean cloth or bandage to stop bleeding.

3. Elevate the injured part – Raise it above heart level to reduce blood flow.

4. Clean the wound – Gently wash with clean water to remove dirt or debris.

5. Apply antiseptic – Prevent infection using antiseptic solutions.

6. Cover the wound – Use a sterile dressing or bandage.

7. Do not remove deeply embedded objects – Instead, pad around them and seek medical help.

8. Seek medical assistance – For severe bleeding, deep wounds, or signs of infection.
