Q

Safety measures for defibrilation

A

Ensure good contact between skin, pads, and paddles
o Use conductive medium, 20 to 25 pounds of pressure
 Place paddles so they do not touch bedding or clothing and are
not near medication patches or oxygen flow
 If cardioverting, turn synchronizer on
 If defibrillating, turn synchronizer off
 Do not charge device until ready to shock
 Call “clear” three times; follow checks required for clear
o Ensure no one is in contact with patient, bed, or equipment

Q

Arrythmia

A

Disorders of formation or conduction (or both) of
electrical impulses within heart
Can cause disturbances of
o Rate
o Rhythm
o Both rate and rhythm
Potentially can alter blood flow and cause
hemodynamic changes
Diagnosed by analysis of electrographic waveform

Q

Normal Electrical Conduction

A

SA node (sinus node)
AV node
Conduction
Bundle of His
Right and left bundle branches
Purkinje fibers
Depolarization = stimulation = systole
Repolarization = relaxation = diastole
