Safety first

Call 911 immediately for severe bleeding, difficulty breathing, chest pain, signs of stroke, loss of consciousness, or any life-threatening emergency. First aid is not a substitute for professional medical care — when in doubt, seek emergency help.

Needs verification

  • Specific current CPR/first-aid technique steps, since guidelines are periodically updated by the American Heart Association and American Red Cross.

We left these specific numbers out until they're checked against current official sources.

AThe super simple explanation

For minor cuts, apply pressure with a clean cloth to stop bleeding, then clean and bandage the wound.

For burns, cool the area with cool (not ice-cold) running water for several minutes.

For choking, if someone can't cough, speak, or breathe, call 911 and perform abdominal thrusts if trained.

Always call 911 for severe injuries, heavy bleeding, difficulty breathing, or if you're unsure of the severity.

BWhy does this even matter?

  • Quick, correct first aid can limit injury severity and sometimes save a life before professional help arrives.
  • Knowing basic steps reduces panic and helps you act calmly and effectively in an emergency.
  • Understanding when something needs 911 versus home care prevents both dangerous delays and unnecessary panic.

COkay, how does it work?

Check if the person is conscious, breathing, and whether the scene is safe for you to approach.

DShow me an example

A kitchen cut

Someone cuts their finger while chopping vegetables.

They apply direct pressure with a clean towel for a few minutes, then wash and bandage it once bleeding slows — seeking medical care if it's deep or won't stop bleeding.

Illustrative example with made-up people and numbers — not current rates or rules.

EWords you should know

Direct pressure
Pressing firmly on a wound with a clean cloth to help stop bleeding.
Abdominal thrusts
A technique (sometimes called the Heimlich maneuver) used to help dislodge an object from a choking person's airway.
CPR
Cardiopulmonary resuscitation — chest compressions and rescue breaths used when someone's heart has stopped or they aren't breathing.

FCommon mistakes

  • Applying ice directly to a burn instead of cool running water.
  • Popping blisters from a burn.
  • Hesitating to call 911 when a situation is clearly serious.
  • Attempting abdominal thrusts or CPR without any training when it isn't actually necessary.

GThings to know

  • Formal certification (like through the American Red Cross) teaches hands-on CPR and first aid skills that are best learned in person, not just read about.
  • Keeping a basic first aid kit at home and in your car covers many common minor injuries.
  • Good Samaritan laws in most states offer some legal protection to people who provide reasonable emergency help in good faith, though specifics vary by state.

HQuick recap

  • Call 911 immediately for severe bleeding, breathing problems, or unconsciousness.
  • Use direct pressure for cuts and cool running water (not ice) for burns.
  • Encourage a choking person to cough if they still can; only intervene physically if trained.
  • Consider taking a certified first aid/CPR course for hands-on training.
