Special Considerations for the AED

Question 1

general safety precautions for operating the AED

Answer 1

no one should be in contact with the patient when AED is operating
patient should not be lying in water
patient should not be in contact with metal
DO NOT place pads over any medical patches
hairy chest (Warbington & Vogler) the electrodes will stick to the hair and not the skin

Question 2

AED failure is most commonly due to what?

Answer 2

improper maintenance

Question 3

when should the AED be checked off?

Answer 3

at the beginning of every shift

Question 4

it is recommended that the AED operator should refresh or practice skills every

Answer 4

90 days

Question 5

electrical current for defibrillators is measured in units called

Answer 5

joules

Question 6

most monophasic AED’s have 2 present values range of ___-___ joules

Answer 6

200-360

Question 7

these have life-long batteries, that have tiny electrodes connecing to the heart, positioned beneath one of the clavicles

Answer 7

pacemaker

Question 8

if a patient is in cardiac arrest and has a pacemaker can you use an AED on them?

Answer 8

yes, just don’t put it over the pacemaker

Question 9

beta 1 refers to the (you only have one)

Answer 9

heart

Question 10

beta 2 refers to the (you have 2)

Answer 10

lungs

Question 11

what device provides 4-5 shocks to the heart if it detects shockable dysrhythmia

Answer 11

implantable cardioverter defibrillators

Question 12

is treatment for an unresponsive patient with an ICD the same for any other unresponsive cardiac patient?

Answer 12

yes, just place the electrode pad 1 inch to the side of the ICD

Question 13

to ensure good chest compressions an EMT would be relieved after every

Answer 13

2 minutes

Question 14

this device is an apparatus that depresses the sternum with a compressed gas powered plunger affixed to a backboard

Answer 14

mechanical piston device

Question 15

this device is composed of a wide band that is applied to the chest circumferentially and in some models is attached to the backboard either pneumatically or electrically driven to provide inward constrictive pressure on the thorax, which inturn compresses the heart

Answer 15

load distributing band CPR- Vest CPR

Question 16

this is a piece of equipment that is designed with a valve that limits the amount of air that enters the chest and lungs during the chest recoil phase of active compressions

Answer 16

impedance threshold device

Question 17

this device is placed between the cuffed endotracheal tube of an intubated adult patient and the ventilatory adjunct being used to provide artificial ventilatiions

Answer 17

impedance threshold device

Question 18

in this device air is prohibited from rushing in during the relaxation phase of ventilations, instead allowing the negative intrathoracic pressure to draw more blood toward the heart

Answer 18

impedance threshold device

Question 19

this phase generates the positive pressure to move the blood out of the heart through the arteries

Answer 19

compression

Question 20

this phase increases the negative pressure inside the thorax to improve blood return to the heart

Answer 20

decompression
