Enroute Phase Scenario: The AEMT is dispatched to a local fitness center for a 58-year-old male who collapsed while using a treadmill. A bystander on scene reports that the patient is unresponsive and not breathing. The time of the call is 1412. The response time is estimated at 8 minutes. The AEMT is partnered with an EMT, and a fire department BLS engine crew is also en route. The patient is located inside the gym. It is a warm spring afternoon with moderate traffic in the area. The nearest hospital is 10 minutes away. Gym staff have been instructed to retrieve the on-site AED and bring it to the patient. OnScene Phase Scenario: The patient (approximately 80 kilograms) is found lying supine on the floor of a fitness center. The patient is unresponsive, pulseless, and not breathing. A bystander began chest compressions approximately two minutes before EMS arrival. Gym staff report that the patient had been jogging on a treadmill before suddenly collapsing. The AED has just arrived on scene. The AEMT confirms absence of a carotid pulse and initiates resuscitation efforts. High-quality chest compressions are continued, and a bag-valve mask is connected to high-flow oxygen to begin ventilation. The AED is attached, and the initial rhythm analysis indicates ventricular fibrillation shock advised. No signs of trauma are present. The patient has no known allergies. The patient’s medical history and medications are currently unknown.  What is the primary purpose of continuing CPR immediately after the defibrillation shock?
