BLS Training Manual: Saving Lives Fast

Guide to Basic Life Support for the Public

Introduction to Basic Life Support (BLS)

Why BLS Matters

Cardiac arrest can happen anywhere, anytime—at home, work, or in public.
Immediate CPR can double or triple survival chances.
BLS skills empower anyone to act before medical help arrives.

Key Principles of BLS

Early Recognition – Spotting cardiac arrest (unresponsiveness, no breathing).
Early CPR – Keeps blood flowing to the brain and heart.
Early AED Use – Restores a normal heart rhythm with defibrillation.
Early Advanced Care – Paramedics take over for further treatment.

Remember: The faster you act, the better the outcome!

The Chain of Survival

The 6 critical steps to save a life in cardiac arrest:

Recognize Emergency & Call for Help
- Check for responsiveness (“Are you okay?”).
- Call emergency services (e.g., 108, 112, or local number).
Start CPR Immediately
- Push hard and fast in the center of the chest.
Use an AED (If Available)
- Turn it on and follow voice instructions.
Provide Rescue Breaths (If Trained)
- 30 compressions + 2 breaths (for adults).
Advanced Medical Support
- Wait for EMS (ambulance) to arrive.
Post-Cardiac Arrest Care
- Hospital treatment improves long-term survival.

CPR for Adults & Children

Step-by-Step CPR Guide

Check Safety – Ensure the scene is safe.
Check Responsiveness – Tap and shout.
Call for Help – Yell for someone to call EMS/get an AED.
Start Chest Compressions
- Adults & Teens:
  - Hand Position: Heel of one hand on the center of the chest.
  - Depth: At least 2 inches (5 cm).
  - Rate: 100-120 compressions per minute (to the beat of “Stayin’ Alive”).
- Children (1-12 yrs):
  - Use one or two hands, compress 2 inches deep.
- Infants (Under 1 yr):
  - Use two fingers, compress 1.5 inches deep.
Rescue Breaths (If Trained)
- Tilt head back, pinch nose, give 2 breaths (1 second each).

Using an AED (Automated External Defibrillator)

How an AED Works

Analyzes heart rhythm and delivers a shock if needed.
Safe for untrained users – Just follow voice prompts!

Steps to Use an AED

Turn It On – Open the lid or press the power button.
Attach Pads
- Adults: Place one pad on the upper right chest, the other on the lower left side.
- Children/Infants: Use pediatric pads if available.
Stand Clear – Let the AED analyze the heart rhythm.
Deliver Shock (If Advised) – Ensure no one touches the victim.
Resume CPR – Follow AED instructions.

Important:

Never remove pads – EMS will take over.
AEDs can’t harm – They only shock if needed.

Choking Relief & Special Situations

Choking Rescue for Adults & Children

Ask, “Are you choking?” – If they can cough, let them try to clear it.
Perform Abdominal Thrusts (Heimlich Maneuver)
- Stand behind, wrap arms around waist.
- Make a fist above the navel, thrust inward and upward.
For Infants:
- Back blows (5 times) + chest thrusts (5 times).

When to Stop CPR

The person starts breathing normally.
EMS arrives and takes over.
You’re too exhausted to continue.

Remember: Even imperfect CPR is better than no CPR!

Practice & Preparedness

How to Stay Ready

✔ Take a BLS Course – Hands-on practice improves confidence.
✔ Learn AED Locations – Malls, offices, and airports often have them.
✔ Teach Others – Share this knowledge with family and friends.
