Adult CPR Protocol: Airway, Breathing, Compressions, and AED Use

One-Rescuer CPR Sequence

1. Assess Responsiveness: Tap and shout.
2. Call 911 / Activate Emergency Response: Get AED.
3. Open Airway: Head-tilt/chin-lift (jaw thrust if trauma suspected).
4. Check Breathing: Look, listen, feel ≤10 seconds. Absent or agonal → start CPR.
5. Chest Compressions: Center of chest, 5–6 cm depth, 100–120/min. Allow full recoil.
6. Rescue Breaths: 2 breaths after 30 compressions (30:2). Each breath over 1 sec, visible chest rise.
7. Continue: Uninterrupted cycles until AED attached, EMS takes over, or patient moves/breathes normally.

If AED arrives: apply pads, follow prompts, resume CPR immediately after shock/no-shock advisory.
