children from 1 year of age to puberty
When looking for a pulse on a child from one year to puberty, where should you check?

What is the recommended BLS sequence for the 2020 ILCOR guidelines?

What are the signs of an obstruction of the airway? A. Poor air exchange B. High-pitched noise while inhaling C. Inability to speak D. All of the above
D. All of the above
What are the vital characteristics of first-rate CPR? A. Starting chest compressions within 10 seconds of recognition of cardiac arrest B. Pushing hard and fast C. Minimizing interruptions D. All of the above

The brachial artery located on the upper arm is used
in infants below 1 year old.
Rapid defibrillation
increases the chance of effectively restoring a normal heart rhythm.
Early CPR
provides vital oxygen to the brain and vital organs increasing the likelihood of recovery.
Post cardiac arrest care
reduces the possibility of long-term impairment and increases the chance of a victim making a full recovery.
