You respond to an office building to find a middle-age man in cardiac arrest. Coworkers are performing CPR and state that the patient has been down for approximately 10 minutes. You attach the AED, push the analyze button, and receive a “shock advised“ message. You should…
Ensure that nobody is touching the patient and then defibrillate
