Final answer:
When alone treating an unresponsive, apneic adult, modify CPR steps by adjusting ratio, omitting compressions, summoning AED, and skipping BVM ventilations.
Explanation:
The steps modified when alone treating an unresponsive, apneic adult:
- CPR ratio change: Adjust compression to ventilation ratio.
- Omit compressions: Compressions can be skipped, use ventilations only.
- Summon AED: Call for an AED and activate EMS.
- Single rescuer: Single rescuers skip BVM ventilations.
Trained first responders may combine chest compressions and mouth-to-mouth breathing, but bystanders typically perform compression-only CPR for simplicity and effectiveness.
