Five First-Aid Skills Every Household Should Actually Know

1. Hands-Only CPR

When someone’s heart suddenly stops — cardiac arrest — they collapse, become unresponsive, and aren’t breathing normally (or are only gasping). Their survival now depends on getting blood moving until help arrives, and that is exactly what CPR does. For a teen or adult who collapses this way, the AHA promotes Hands-Only CPR, which is simple enough to remember in a crisis: call 911 (put it on speaker, and send someone for an AED if one’s nearby), then push hard and fast in the center of the chest — about two inches deep, at a rate of 100 to 120 compressions a minute. That pace is famously the beat of “Stayin’ Alive,” and humming it genuinely helps. Let the chest rise fully between pushes, and don’t stop until help takes over or the person revives.

If an AED (automated external defibrillator) is available — increasingly common in offices, gyms, and public buildings — use it. Turn it on and follow the spoken instructions exactly; it analyzes the heart and will only deliver a shock if one is needed, so you can’t get it wrong by trying. Two notes worth remembering: Hands-Only CPR is for adults and teens, while infants, children, and people who collapsed from drowning or a drug overdose need traditional CPR that includes rescue breaths — another reason to take a full class. Doing something almost always beats doing nothing; the only truly wrong move in cardiac arrest is hesitation.

2. Helping Someone Who’s Choking

Choking is terrifyingly fast and silent. The universal sign is hands clutched at the throat, and the key question is whether the person can move air. If they can cough forcefully, speak, or breathe, the blockage is partial — encourage them to keep coughing, which is the most effective thing, and don’t interfere. But if they can’t breathe, speak, or cough, it’s a severe obstruction and you must act immediately.

For a choking adult or child, current AHA guidance is to alternate five back blows with five abdominal thrusts, repeating the cycle until the object comes out or the person becomes unresponsive. (This is an update worth knowing — older training taught abdominal thrusts alone for adults; the back blows are now included.) Deliver the back blows firmly between the shoulder blades with the heel of your hand, and the abdominal thrusts inward and upward just above the navel. For an infant under one year, the technique is different and gentler: alternate five back blows with five chest thrusts — never abdominal thrusts, which can injure a baby’s organs. If anyone choking becomes unresponsive, call 911 if it hasn’t been done and begin CPR. One firm rule throughout: never do a blind finger sweep into the mouth, as it usually pushes the object deeper.

3. Stopping Severe Bleeding

A person can bleed to death in minutes, faster than an ambulance can arrive — which is why the national Stop the Bleed campaign exists to teach this skill to ordinary people. The single most effective action is the simplest: firm, direct pressure. Call 911 (or direct someone to), then press down hard on the wound with your hands, using any cloth you have — a shirt, a towel, gauze — which does not need to be sterile. Press with your full weight, keep the person lying down, and hold continuous pressure for at least several minutes without lifting to peek, because every time you check, you let the clot break and the bleeding restart. Maintain pressure until help arrives.

For a deep wound on an arm or leg where pressure alone won’t stop the flow, pack the wound — firmly stuff clean cloth or gauze directly into it — and keep pressing hard on top. And for life-threatening bleeding from a limb that direct pressure can’t control, a tourniquet can save a life: place it two to three inches above the wound (never on a joint), tighten it until the bleeding stops, note the time, and — this part matters — do not loosen or remove it. Leave it for the medical professionals. A tourniquet is painful and that’s expected; keeping someone alive comes first. One more rule: if an object is impaled in a wound, don’t pull it out — press around it instead, since it may be plugging the very vessel that would otherwise bleed.

4. Spotting a Stroke or Heart Attack

This skill isn’t about treatment — it’s about recognition and speed, because for both a stroke and a heart attack, tissue is dying every minute and the treatments that save people only work within a narrow window. For a stroke, the AHA’s memory aid is FAST: Face drooping (ask them to smile — is it uneven?), Arm weakness (ask them to raise both arms — does one drift down?), Speech difficulty (ask them to repeat a simple sentence — is it slurred?), and Time to call 911. Some versions add Balance loss and Eye/vision changes. Call 911 the moment you see any of these — even if the symptoms go away — and note the time they started, because that single fact shapes the treatment doctors can give. Don’t give a suspected stroke patient aspirin; if it’s a bleed in the brain, aspirin makes it worse.

A heart attack can look less dramatic than the movies suggest. Watch for chest pressure, squeezing, or pain that may radiate to the arm, jaw, neck, back, or stomach, along with shortness of breath, a cold sweat, nausea, or lightheadedness — and know that symptoms can be subtler in women. The response is the same: call 911, and don’t drive to the hospital. Emergency responders begin life-saving treatment the moment they arrive and en route, and people have died in the passenger seat on the way to the ER. If the person becomes unresponsive and stops breathing normally, that’s cardiac arrest — start CPR.

5. Treating a Burn the Right Way

Burns are among the most common household injuries, and they’re also the ones people most reliably treat wrong, thanks to stubborn old myths. Here’s what actually works. First, remove jewelry and clothing near the burn — but not anything stuck to the skin — before the area swells. Then cool the burn under clean, cool (not icy) running water for about 10 to 20 minutes, or until the pain eases. This is the single most important step: it carries heat out of the skin and limits the damage, and it’s worth doing as soon as possible after the burn. If there’s no running water, use a cool, wet compress.

Now the myths to abandon. Don’t put ice on a burn — it’s so cold it causes further tissue damage. And don’t apply butter, oil, toothpaste, or any greasy home remedy; far from helping, they seal heat into the skin and raise the risk of infection. Once cooled, cover the burn loosely with a clean, non-stick dressing or even plastic wrap, and leave blisters intact — they protect the healing skin underneath. Over-the-counter pain relief is fine. Seek medical care for any burn that is large (bigger than the person’s palm), deep, or located on the face, hands, feet, genitals, or a major joint — and call 911 for chemical and electrical burns, since even a small-looking electrical burn can mask serious internal injury.

The Three Rules That Tie It All Together

Behind all five skills sit three habits that make them work. First, call 911 early — getting professional help on the way is itself a life-saving act, and a dispatcher can coach you through what to do while you wait, so put the phone on speaker and keep your hands free. Second, get real training. Knowing these steps on paper is a fine start, but in a true emergency, adrenaline erases anything you haven’t practiced with your hands; a few hours in a certified Red Cross or AHA course turns vague knowledge into reflexes you can trust, and refreshing it every couple of years keeps it sharp.

Third, keep a stocked first-aid kit and make sure everyone in the household knows where it is. A good kit holds gloves, gauze and dressings, adhesive bandages, tape, antiseptic, scissors, and a few specific items like a tourniquet if you’ve been trained to use one — and it’s worthless if it’s buried in a closet no one can find at 2 a.m. Check it once a year, replace what’s expired, and post your local emergency numbers somewhere visible. Preparation is quiet and boring right up until the moment it’s the most important thing in the world.

One honorable mention belongs in every household where someone has a serious allergy: know the signs of anaphylaxis — sudden trouble breathing, swelling of the face, lips, or throat, hives, or faintness after a food, sting, or medication — and know how to use an epinephrine auto-injector. If a person at risk has one prescribed, learn the steps before an emergency, use it at the first sign of a severe reaction (it works fast and is far safer than waiting), and always call 911 afterward, since symptoms can return. Like the five core skills, it’s a few minutes of learning that can buy someone the time they need.
