The EMT should use and AED on a child between 1 and 8 years of age if:
they are not breathing and has a weakly palpable pulse
their condition is rapidly progressing to cardiac arrest
perdiatric pads and an energy-reducing device are available
special pads are used and the child has profound tachycardia
Prior to attaching the AED to a cardiac arrest patient, the EMT should

dry the chest if it is wet
perform CPR for 30 seconds
assess a pulse for 20 seconds

regularly take illegal drugs
have had a stroke in the past
are older than 40 years of age
