First Aid

Essential medical knowledge for emergencies: life-saving skills everyone should have.

Why First Aid Matters

Professional help is minutes away. Cardiac arrest kills brain cells in four. The gap between the two is where bystanders save lives.

Knowing what to do can:

Save lives
Prevent injuries from worsening
Reduce recovery time
Keep the patient calmer
Keep you calmer

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

Stay Calm

Take a breath
Assess before acting
Your calm helps the victim

Do No Harm

Don't move unless necessary
Don't remove embedded objects
Don't give food/water to unconscious

Get Help

Call 911 for serious situations
Don't be a hero alone
Delegate tasks to bystanders

Document

Note time of incident
Note time of interventions
Note changes in condition
This helps medical professionals
