Answer :
Final answer:
The correct answer is CPR is optional. While trained first responders perform both chest compressions and ventilations, bystanders are recommended to perform compression-only CPR. AEDs, carried by ambulances and available in public places, are to be used in conjunction with CPR. Therefore the correct answer is B).
Explanation:
The presence of an advanced airway in an adult victim during 2 rescuer CPR does not make ventilation optional, unnecessary, or contraindicate the use of an Automated External Defibrillator (AED). Trained first responders will perform both chest compressions and provide ventilations with advanced airways in placed.
For bystanders without medical training, compression-only CPR is recommended, whereas professional rescuers are trained to provide ventilations as well. It is also important to note that it is common for ambulances to carry AEDs, and these devices are designed to be used by laypersons in public places.
AEDs automatically diagnose the patient's heart rhythm and apply the appropriate shock, and CPR is typically recommended before using a defibrillator.
