Burns, Cuts, and Choking
These three injuries happen more than everything else combined — they are the everyday emergencies that occur in kitchens, workshops, and dining rooms while nobody is expecting them. None of them require a medical degree to handle — about five minutes of [[first-aid-basics|first aid]] knowledge and the ability to stay calm covers all three for life, but they do require knowing what to do before it happens, because an emergency room visit adds thousands of dollars to an injury that often needs twenty minutes and a bandage. Your brain does not learn new things during a crisis — it only executes the skills it already has, which is why the only time to learn is now, not when someone is bleeding, screaming, or turning blue.
Burns
Run cool water over the burn for at least ten minutes — not ice, not butter, not toothpaste, which are common mistakes that make burns worse. Cool water pulls heat out of the damaged tissue and reduces the actual depth of the burn; ice causes frostbite on damaged skin, and butter or oil traps heat in, making the injury deeper. After the water, cover it loosely with a clean bandage or gauze and do not pop blisters — the fluid inside is sterile and the blister acts as a natural bandage protecting new skin underneath. Popping a blister opens a direct path for infection — bacteria enter tissue that has no intact skin barrier, making a burn wound uniquely vulnerable, and infection in a burn is often more dangerous than the burn itself because the immune response in the damaged area is already compromised.
Go to the [[when-to-go-to-the-er|ER]] if the burn is larger than your palm, if it is on the face, hands, feet, or joints, or if the skin is white, waxy, or charred. Minor burns hurt badly. Severe burns sometimes do not hurt at all because the nerves are themselves destroyed, and the absence of pain actually means the damage is significantly worse — a burn that does not hurt has reached the deepest layers of skin and requires immediate emergency care. [[how-to-read-a-medication-label|Ibuprofen]] helps with both pain and the underlying inflammation, and aloe vera or antibiotic ointment keeps the skin from drying and cracking during healing.
Cuts
Apply direct pressure with a clean cloth and hold it for at least a full ten minutes without peeking — the temptation to check is strong, but every peek breaks the clot forming underneath. If blood soaks through, add another cloth on top — do not remove the first one, because the clot forming in that layer is extremely fragile and removing it restarts the bleeding from scratch. Once the bleeding stops, clean the cut with plain water — not hydrogen peroxide or alcohol, which kill the healing cells as effectively as they kill bacteria. Apply antibiotic ointment and cover with a bandage, changing it daily and watching for signs of infection — increasing redness, warmth, swelling, or pus.
Stitches are needed if the cut is deep enough to see fat or muscle, if the edges do not stay together on their own, or if it is on the face where scarring matters. Get to urgent care or the [[when-to-go-to-the-er|ER]] within six hours — after that, the wound may be closed with increased infection risk or left to heal open, which takes longer and scars worse. A [[knife-skills|knife]] cut in the [[kitchen-basics|kitchen]] is the most common type of laceration treated in emergency rooms, and the majority happen during three predictable activities: cutting toward your hand, using a dull knife that slips, and trying to catch a falling knife. The rule is almost absurdly simple — cut away from your body, keep your knife sharp, and let a falling knife hit the floor. A replacement knife costs around twenty dollars — a severed tendon costs surgery.
Choking
If the person is coughing hard, let them cough — a strong cough generates more airway pressure than anything you can do from the outside. If they cannot cough, cannot speak, and cannot breathe, — the universal sign is both hands clutching the throat — act immediately. Stand behind them, make a fist just above the belly button, grab the fist with your other hand, and pull sharply inward and upward — this is the [[heimlich-maneuver|Heimlich maneuver]]. Five abdominal thrusts in rapid succession. If it does not clear, keep going — do not stop to call for help until the airway is open or the person loses consciousness. If they go unconscious, lower them to the ground, call for emergency help, and begin [[cpr-basics|CPR]], checking the mouth between compression cycles for the dislodged object.
For infants, the technique is different — hold the baby face-down on your forearm and give five firm back blows between the shoulder blades with the heel of your hand. Then flip the baby face-up and give five chest thrusts with two fingers on the center of the breastbone, alternating until the object comes out or help arrives. Never blindly sweep a finger in an infant's mouth — you can push the object deeper into the airway — only remove it if you can clearly see it.
