Here I have attached a photo to help you with this:
Stress makes you nervous almost and makes our heart go faster and your brain think??? it could give you a heart attack?? i wouldn't trust this lol
Answer:
Safeguard
The rest are wrong, its not a saftey violation because it inhances saftey, and its not an emergency because again saftey is being used.
The American heart association changed ABC (Airway, Breathing, Compressions) to CAB (Compressions, Airway, Breathing) because when the ABC sequence to perform CPR was performed, people would spend so much time trying to open the airway that there was a delay in chest compressions making rescue breathes harmful. With the new CAB sequence people initiate chest compressions sooner and ventilation is only slightly delayed.
Hope this helps!
