Emergency Response for Sudden Collapse
When a person suddenly collapses, the first critical step is to call 911 immediately to activate the emergency response system, followed by starting chest compressions if the person is unresponsive and not breathing normally. 1
Initial Assessment and Response Algorithm
Ensure scene safety - Before approaching the collapsed individual, quickly assess for any dangers to yourself or others
Check responsiveness - Tap the victim's shoulder and ask loudly "Are you all right?" 1
Activate emergency response system - If unresponsive, immediately call 911 1, 2
- This is the critical first step that significantly improves survival outcomes
- Don't delay this step as every minute decreases survival chances
Return to the victim - After calling 911, quickly check for breathing and pulse (take no more than 10 seconds) 1
Begin appropriate intervention based on assessment:
If no normal breathing (or only gasping) and no definite pulse:
- Begin chest compressions at a rate of 30:2 2
- Push hard and fast in the center of the chest
- Allow complete chest recoil after each compression
- Minimize interruptions in compressions
If pulse is present but no normal breathing:
- Provide rescue breaths (1 breath every 6 seconds)
- Recheck pulse every 2 minutes 1
Key Considerations
Quality of compressions matters: The American Heart Association emphasizes that chest compressions should be of adequate rate and depth with minimal interruptions 2
Hands-only CPR is acceptable: For untrained bystanders or those not confident in providing rescue breaths, hands-only CPR (compression-only) is recommended and can be as effective as conventional CPR 2
Avoid common pitfalls:
Even if the victim quickly regains consciousness, they should still receive medical evaluation as this could indicate serious underlying conditions 1
Special Circumstances
For elderly patients, presentation may be atypical and require more careful assessment 1
Bystanders often hesitate to call 911 due to misconceptions about the seriousness of the situation or incorrect understanding of how to access emergency services 3
Research shows that the public responds differently based on the type of symptom they observe, with confusion/decreased level of consciousness and weakness more likely to prompt a 911 call than other symptoms 4
By following this algorithm and understanding these key considerations, you can provide the best possible chance of survival for someone who has suddenly collapsed.
