Emergency Medical Technician (EMT) Basic Certification Practice Exam

What is the correct treatment approach for someone undergoing asphyxial cardiac arrest?

1. Call for help and wait for AED

2. 5 cycles of CPR prior to retrieving the AED

3. Immediate defibrillation on the first shock

4. Breathe for the patient and wait for respiration

The correct answer is: 5 cycles of CPR prior to retrieving the AED

In cases of asphyxial cardiac arrest, the primary treatment approach focuses on high-quality cardiopulmonary resuscitation (CPR) as a crucial initial step. When performing CPR, it is essential to recognize that the underlying issue is often due to a lack of oxygen rather than a primary cardiac process. Providing 5 cycles of CPR before retrieving the Automated External Defibrillator (AED) ensures that the patient receives immediate and effective chest compressions, which are vital for restoring circulation and delivering oxygen to vital organs. This approach also allows for the establishment of some ventilations if needed, increasing the chances of successful resuscitation when advanced support is available. Furthermore, minimizing interruptions in chest compressions during the early phase of resuscitation is critical for improving outcomes. In contrast, waiting for an AED before initiating CPR limits immediate intervention, and immediate defibrillation is not indicated during asphyxial arrest if the rhythm is not shockable. Bystander rescue breaths would be more effective if incorporated early, but they should not replace the need for compressions at that critical moment. Thus, performing 5 cycles of CPR first aligns with recommended resuscitation protocols for asphyxial cardiac arrest, focusing on oxygenated blood flow
