BLS Certification Manual: Conclusion

Conclusion

Basic Life Support prepares trained responders to recognize and respond to cardiac arrest, respiratory emergencies, severe choking, and other immediately life-threatening situations. Effective BLS requires rapid assessment, high-quality CPR, appropriate ventilation, early AED use, and effective teamwork when multiple responders are available.

Adult BLS Priorities

For an unresponsive adult who is not breathing normally:

1. Activate emergency response
2. Check breathing and pulse for no more than 10 seconds
3. If no definite pulse is present, begin CPR
4. Compress at 100-120 per minute
5. Compress at least 2 inches while avoiding excessive depth
6. Use a 30:2 compression-to-ventilation ratio without an advanced airway
7. Use an AED as soon as possible
8. Minimize interruptions

If a pulse is present but breathing is inadequate, provide 1 breath every 6 seconds.

Pediatric BLS Priorities

For an infant or child who is unresponsive and not breathing normally:

• Activate emergency response
• Assess breathing and pulse for no more than 10 seconds
• Begin appropriate CPR or rescue breathing
• Compress at 100-120 per minute
• Use age-appropriate depth and technique
• Use 30:2 for one rescuer
• Use 15:2 for two rescuers
• Attach an AED as soon as possible

If a pulse is present but breathing is inadequate, give 1 breath every 2-3 seconds.

Infant Compression Technique

Use:

• The heel of one hand, or
• The two-thumb encircling-hands technique

Do not use the older two-finger CPR technique.

Choking

For severe choking:

• Adults and children: 5 back blows followed by 5 abdominal thrusts
• Infants: 5 back blows followed by 5 chest thrusts using the heel of one hand

If the person becomes unresponsive, begin CPR.

Team Response

When multiple trained responders are available:

• Assign clear roles
• Use direct communication
• Monitor CPR quality
• Switch compressors before fatigue reduces performance
• Minimize interruptions
• Communicate important changes immediately

Final Reminder

BLS emergencies require immediate action. Recognize the emergency quickly, provide high-quality care without delay, and coordinate with your team until professional help arrives.

BLS is built around a small number of critical priorities:

Rapid recognition → high-quality CPR → appropriate ventilation → early AED use → coordinated teamwork
