When should the rescuer operating the AED clear the victim?
During analysis and before shock delivery
What is the preferred method for pulse check in an infant?
Place 2 or 3 fingers on the inside of the upper arm, mid way b/w the infant's elbow and shoulder
After an AED delivers a shock, what should the rescuers do next?
Resume CPR, starting with chest compressions
When performing chest compressions for an infant in a 2-rescuer situation, you should put 2 ______________ in the center of the chest, on the lower half of the breastbone.

Activate the emergency response system and get the AED
What does a chest compression feedback device monitor?
Chest recoil, compression rate and compression depth
As you are providing CPR, your colleague arrives, turns on the AED, and follows the prompts. The AED analyses the rhythm and does not advise a shock. After you immediately resume CPR, how do you continue treating the patient?
Continue CPR until prompted by the AED to allow a rhythm check, the ALS team arrives, or the patient starts to move
