If there is "no pulse or response," what is the first step to take?

1. Apply AED immediately

2. Check for breathing

3. Initiate CAB's

4. Call emergency services

The correct answer is: Initiate CAB's

When assessing a situation where there is "no pulse or response," the first step of initiating CAB's (Compressions, Airway, Breathing) is crucial. This sequence is pivotal in cardiopulmonary resuscitation (CPR) as it prioritizes effective blood circulation and oxygenation to vital organs. Starting with compressions ensures that if the heart is not beating, you can provide artificial circulation to maintain oxygen delivery to the brain and other critical areas of the body. This action can be essential in preventing brain damage and extending the time a patient can survive without a pulse. After initiating compressions, the next steps would typically involve checking the airway and providing breaths if appropriately trained and equipped, alongside calling for emergency services. However, the immediate focus must be on providing chest compressions to maximize the chances of survival until advanced medical help arrives.
