When performing high-quality CPR on an adult, it is essential to ensure that the following actions are being accomplished:

1. Chest Compressions:
   • Depth: Compress the chest at least 2 inches (5 cm) but not more than 2.4 inches (6 cm).
   • Rate: Perform compressions at a rate of 100 to 120 compressions per minute.
   • Recoil: Allow complete chest recoil after each compression to let the heart refill with blood.
   • Minimize Interruptions: Keep interruptions in chest compressions to less than 10 seconds.
2. Ventilations:
   • Ratio: If not using an advanced airway, use a compression-to-ventilation ratio of 30:2.
   • Volume: Deliver each breath over 1 second, making the chest rise visibly.
   • Avoid Excessive Ventilation: Provide just enough air to make the chest rise to avoid over-inflation of the lungs.
3. Compression Technique:
   • Hand Placement: Place the heel of one hand on the center of the chest (on the lower half of the breastbone), and place the other hand on top, interlocking fingers.
   • Body Position: Position your shoulders directly over your hands and keep your arms straight to use your body weight for effective compressions.
4. Team Dynamics:
   • Communication: Clearly communicate with team members to ensure coordinated and effective resuscitation efforts.
   • Role Assignment: Assign specific roles (compressor, ventilator, AED operator) and rotate compressors every 2 minutes to prevent fatigue.
5. Use of AED:
   • Prompt Application: Attach and use an Automated External Defibrillator (AED) as soon as it is available.
   • Follow Instructions: Follow the AED prompts for analyzing the heart rhythm and delivering shocks if indicated.
