CPR (Adult)

1. Check responsiveness
Tap shoulder, shout "Are you OK?" — if no response, call 911
2. Chest compressions
Center of chest, 2-2.4 inches deep, 100-120/min. Sing "Stayin' Alive" for rhythm.
3. Rescue breaths
30 compressions → 2 breaths (tilt head back, pinch nose, 1 sec each)
4. Continue
Don't stop until help arrives or person responds

Choking Response

StepAction
1. Ask"Are you choking?" — if they can cough or speak, encourage coughing
2. HeimlichStand behind, fist above navel, thrust inward and upward
3. Repeat5 back blows → 5 abdominal thrusts → repeat until object dislodged
4. If aloneCall 911 first, then use a chair back to self-administer thrusts

Bleeding Control

StepAction
Direct pressureClean cloth/gauze directly on wound — press firmly for 10-15 min
ElevateRaise wound above heart if possible
TourniquetLast resort for life-threatening limb bleeding — 2-3 inches above wound

Burns

DegreeSymptomsTreatment
1stRed, painful, no blistersCool water 10 min, aloe vera, OTC pain relief
2ndBlisters, severe painCool water, DON'T pop blisters, sterile dressing — seek medical if >3 inches
3rdWhite/charred, may be painlessCall 911 — do NOT apply water or creams. Cover loosely with sterile cloth.
Pro Tip: Hands-only CPR (compressions without breaths) is nearly as effective as full CPR for adults and much easier for bystanders. Push hard and fast in the center of the chest — 100-120 beats per minute. You can't make things worse; doing nothing is the only wrong choice.
