If an inhaler does not relieve an asthma attack, call 911 immediately, as the attack may become life-threatening.

For mild allergic reactions, an antihistamine like diphenhydramine (Benadryl) can help reduce symptoms.

If someone is choking and unable to breathe, the first step is to ask if they need help. If they cannot respond, perform abdominal thrusts (Heimlich maneuver).

Swelling, deformity, severe pain, and inability to move the injured area are signs of a fracture.

Signs of heat stroke include confusion, hot/dry skin, and rapid pulse. Unlike heat exhaustion, the victim does NOT sweat.

A hypothermic person should be rewarmed gradually using dry blankets and warm fluids. Rapid warming can cause shock.

A person with a spinal injury should not be moved unless absolutely necessary. Keep them still and stabilize their head and neck.

Inhaling toxic fumes can cause serious respiratory issues, and the first step is to move the victim to fresh air.

A splint prevents movement of a broken or injured limb to avoid further damage.

If a person is unable to speak or cough, perform the Heimlich maneuver (abdominal thrusts) to help expel the obstruction.

If a nosebleed lasts longer than 10 minutes, seek medical attention as it could indicate a more serious problem.

Before assisting a victim, always turn off the power source to prevent further injury.

The recommended compression rate is 100-120 compressions per minute.

Agonal gasps (irregular, gasping breaths) are not normal breathing. CPR should be started immediately.

Cleaning the wound with water and covering it with a sterile dressing prevents infection and promotes healing.

Applying direct pressure to a wound is the most effective way to stop severe bleeding.

Compressions should be at least 2 inches (5 cm) deep to effectively circulate blood.

Frostbitten areas should be warmed slowly using warm water (not hot) to avoid further damage.

Applying firm, direct pressure is the most effective way to stop bleeding from a deep laceration.

Asthma inhalers should be used when symptoms appear, not only when a person is unconscious. Delaying treatment can be dangerous.

Unlike heat exhaustion, heat stroke causes hot, dry skin and confusion, and is a medical emergency.

For adult CPR, hands should be placed in the center of the chest, on the lower half of the sternum.

Symptoms of shock include pale skin, weak rapid pulse, nausea, and excessive thirst. A slow, strong pulse is NOT typically associated with shock.

If a person is unresponsive and has no pulse, CPR should be started immediately to maintain circulation and oxygenation.

Tilting the head back can cause blood to go down the throat. Instead, the person should lean forward and pinch their nostrils.

Animal bites should be cleaned with soap and water, and medical help should be sought to assess infection risk.

During a seizure, keep the person safe by clearing the area and placing them on their side to prevent choking. Do NOT hold them down.

Cold therapy (ice) is recommended for the first 24-48 hours to reduce swelling and pain. Heat can worsen swelling early on.

Laying the person flat and elevating their legs improves circulation and helps restore normal blood flow to the brain.

If you suspect a heart attack, the first step is to call 911 immediately. Early treatment can prevent serious damage or death.

Never hold down a person having a seizure. Instead, clear the area and protect their head while allowing the seizure to pass.

An AED is used when a person is unresponsive and has no pulse. It delivers a shock only if needed.

Installing carbon monoxide detectors in homes and ensuring proper ventilation helps prevent CO poisoning.

Tilting the head back can cause blood to flow into the throat and airway. Instead, the person should lean forward and pinch their nostrils.

Even if a head injury seems minor, delayed symptoms such as confusion, dizziness, or vomiting can indicate a serious problem.

A hypothermic victim should be warmed gradually with dry blankets and warm fluids, avoiding rapid temperature changes.

Common symptoms of poisoning include nausea, vomiting, confusion, and difficulty breathing.

Carbon monoxide is a colorless, odorless, and tasteless gas, making it extremely dangerous.

Never remove an embedded object from a wound. It may be stopping severe bleeding. Apply pressure around the object and seek emergency care.

Wild animal bites carry a high risk of rabies or infection and should always be examined by a medical professional.

Carbon monoxide poisoning prevents oxygen from binding to red blood cells, leading to suffocation and organ failure.

If an inhaler is not available and the attack worsens, call 911 immediately as it may become life-threatening.

Pinching the nostrils and leaning forward helps stop bleeding while preventing blood from flowing into the throat.

A person with low blood sugar should be given a fast-acting sugar source like fruit juice or glucose tablets to restore normal levels.

A person in cardiac arrest will be unresponsive, have no pulse, and will not be breathing normally.

A second-degree burn should be cooled with running water, covered with a clean bandage, and left undisturbed to heal.

Diabetic emergencies can cause confusion, dizziness, sweating, and shakiness due to abnormal blood sugar levels.

Keeping the head and neck still is crucial to prevent further spinal damage.

Applying ice directly to a burn can cause further tissue damage. Instead, use cool (not ice-cold) running water.

The first priority in treating a deep open wound is to apply direct pressure to control bleeding before cleaning and dressing the wound.
