Final answer:
When an AED indicates 'No Shock' advised during cardiac arrest treatment, continue CPR for 2 minutes, ensuring high-quality, uninterrupted chest compressions at the correct depth and rate.
Step-by-step explanation:
When treating a cardiac arrest patient and the automated external defibrillator (AED) indicates "No Shock" advised, you should continue CPR for 2 minutes before reanalyzing the patient's heart rhythm. This recommendation aligns with current CPR guidelines emphasizing continuous, high-quality chest compressions to maintain blood flow to vital organs, and in particular, to prevent brain cell death. Compressions should be at least 5 cm deep and at a rate of 100 compressions per minute. It is critical to maintain this rhythm of chest compressions unless a trained healthcare provider takes over or the patient shows signs of life.
