First Aid 101: Basic Principles and Tips

Simple cuts and scrapes are among the most common injuries. These can usually be treated at home.

• Clean the wound carefully with mild soap and running water.
• If the wound is bleeding, use a clean cloth or gauze to apply mild pressure.
• Once the bleeding stops, apply an antiseptic cream, such as Neosporin.
• Bandage the wound and treat it with care.
• Clean and change the bandage regularly if the wound continues to bleed or drain.

Watch for signs of infection, such as excessive redness, swelling, fever, or drainage. If you suspect infection is likely, seek medical attention right away.

First-degree burns can generally be treated at home.

• Cool the burn immediately by placing it under cool running water for 10 to 15 minutes. (Do not place ice directly on the skin, which can worsen the injury.)
• Soothe the skin by applying aloe vera or burn cream to the burn. Make sure the product is meant for burn treatment.
• Use a sterile gauze bandage to cover the burn. Wrap it securely, but not too tight.
• Use over-the-counter pain relievers like ibuprofen to help ease any pain.
• Inspect the burn for any sign of infection.

If your burn is more serious, such as a second or third-degree burn, seek medical attention immediately.

Choking is a common household danger, especially for children. Choking is always an emergency, and treatment must be given immediately to avoid unconsciousness or worse.

• First, check the airway. See if the person can speak or cough.
• If the person’s airway is blocked, perform the Heimlich maneuver. It may take several attempts before you succeed in opening the airway.
• If you cannot clear the airway or the person becomes unresponsive, call 911 immediately.

Avoid slapping the back of a choking person, as this can push the obstruction further down the airway.

Nosebleeds are generally very minor injuries that can be managed without medical intervention.

• Have the person sit upright and pinch their nostrils. (Make sure that they are still able to breathe.)
• Have them lean forward slightly to avoid swallowing blood, which could lead to vomiting.
• After five minutes, check to see if the bleeding has stopped. If not, continue this process for another five minutes.
• Consider applying a cold pack to the nose while pinching it closed.

If the nosebleed won’t stop and leads to excessive blood loss, seek medical attention. Doing so is especially important if the person becomes dizzy or weak.

For sprains or strains, employ the RICE method: rest, ice, compression, and elevation.

• Rest the injured area.
• Apply ice to reduce swelling.
• Use a compression bandage.
• Elevate the limb to minimize inflammation.

Bites from animals, especially dogs or wild creatures, can easily lead to infection. It is essential to take immediate steps to avoid this.

• Wash the wound with soap and water.
• Apply an antiseptic cream.
• Use a clean cloth or gauze pad to apply pressure and control bleeding.
• Seek medical help as soon as possible, particularly if the animal is wild or unknown, as vaccination for rabies may be needed.

Fainting is rarely dangerous in itself. However, it can lead to severe injuries if someone hits their head or is otherwise injured in a fall.

• If someone feels light-headed or dizzy, encourage them to sit down and lower their head below their knees.
• If they've already fainted, make sure they're lying down and elevate their legs.
• Once they regain consciousness, keep them lying down for a few minutes, and then help them sit up slowly.
• Offer them something to eat or drink.
• Monitor them for any difficulty in breathing, communicating, or thinking clearly.

If the cause of fainting isn’t apparent—such as dehydration—seek medical evaluation to rule out any serious underlying conditions.

The average home is full of potentially toxic substances. The signs of poisoning can vary widely depending on the substance involved. If someone has ingested, inhaled, or come into skin contact with a poisonous substance, it is generally unwise to treat the problem yourself. Instead, call Poison Control or emergency services immediately for guidance.

Eye injuries can be especially painful and frightening.

• For minor irritants like dust or sand, encourage the person to blink or use an eye wash station to flush the eye with water.
• If a chemical substance or foreign object is embedded in the eye, do not attempt to remove it. Cover the eye with a clean cloth or cup without putting pressure on the eye, and seek medical attention immediately.

Broken or dislocated bones are, unfortunately, a relatively common injury.

• If you suspect a fracture or dislocation, do not try to realign the bone yourself.
• Keep the injured area as still as possible, using clothing or blankets for support.
• Apply ice packs wrapped in cloth around the injury to minimize swelling.
• Seek medical attention as quickly as possible.

Heat-related illnesses are a significant threat during hot or humid weather, especially for people who work outside. This situation always requires immediate action.

• If you notice someone showing the symptoms of heat exhaustion, move them to a cooler environment, such as inside a building or in the shade.
• Give them water.
• If possible, apply cold, damp cloths to their body.
• Monitor them to see how well they recover.

If you suspect that someone is experiencing heat stroke—a more severe condition where the individual may be confused, faint, or have seizures—call emergency services immediately and take steps to cool them down rapidly.

Cold weather can be just as dangerous as hot. Hypothermia and frostbite are both serious conditions, and both require you to raise the body temperature of the affected person right away.

• For hypothermia, move the individual to a warm environment and wrap them in blankets or use your body heat to warm them.
• For frostbite, soak the affected area in warm (not hot) water. Do not rub the area, as this can cause more damage.

In both cases, do not attempt to complete treatment on your own. Seek medical attention as soon as possible.

A foundational knowledge of first aid principles can help prevent serious injuries and save lives. At the very least, it will allow you to provide care until emergency services arrive or until you can transport an injured person to the nearest emergency room.
