The Universal Response
For any emergency, remember DR. ABC:
| Step | Action | What to Do |
|---|---|---|
| D | Danger | Is the scene safe for you? |
| R | Response | Is the person conscious? |
| A | Airway | Is the airway clear? |
| B | Breathing | Are they breathing normally? |
| C | Circulation | Is there severe bleeding? |
Quick Reference: Common Emergencies
Unconscious, Not Breathing
- Call 911 (or have someone call)
- Start CPR immediately
- Use AED if available
- Continue until help arrives
Severe Bleeding
- Apply direct pressure with cloth
- Maintain pressure, don't remove cloth
- If blood soaks through, add more cloth on top
- Use tourniquet only if pressure fails and bleeding is life-threatening
- Keep victim warm, call 911
Choking (Adult)
- Ask "Are you choking?"
- Give 5 back blows between shoulder blades
- Give 5 abdominal thrusts (Heimlich)
- Alternate until object expelled or person becomes unconscious
- If unconscious, begin CPR
Heart Attack Signs
- Chest pain/pressure (may radiate to arm, jaw, back)
- Shortness of breath
- Cold sweat
- Nausea
- Lightheadedness
Action: Call 911, have person rest, give aspirin if not allergic
Stroke Signs (FAST)
- Face drooping
- Arm weakness
- Speech difficulty
- Time to call 911
Action: Call 911 immediately. Note time symptoms started.
The Chain of Survival
For cardiac arrest:
1. Early Recognition → 2. Early CPR → 3. Early Defibrillation → 4. Advanced Care
Each link matters. Bystander action before EMS arrival dramatically improves survival.
Legal Protection: Good Samaritan Laws
In most jurisdictions, Good Samaritan laws protect rescuers who:
- Act in good faith
- Provide care within their training
- Don't accept compensation
- Don't act with gross negligence
Key principle: Reasonable care, not perfect care, is the standard.
Always:
- Get consent if person is conscious
- Identify yourself and ask "May I help you?"
- Implied consent exists for unconscious victims
First Aid Mindset
