Electrical Safety
What is electricity?
a medium that provides a means for transferring energy from one place to another
Flow of current occurs when
a person or conducting object bridges the gap between live conductors and the ground
Heart lung machines can cause the monitor to have what?
artifact
Ground Fault Circuit Interrupter (GFCI)
-fast-acting circuit breaker that is sensitive to very low levels of fluid leakage to ground -if fluid leakage becomes hazardous, it interrupts the circuit
Circuits of how much voltage can KILL?
110v
Most hospital use two levels of voltage, which are?
110v 220v
Heater/Cooler are designed to run on this amount of voltage?
220v
Wet area use these kind of circuits...
GFCI (ground fault circuit interrupter)
High voltage or low voltage can cause ventricular fibrillation.
Low voltage
What kind of electricity can a heart-lung machine produce?
Static
______ ___ is the factor that causes injury in electric shock, but ____ _________ will determine the path of flow.
current flow; body resistance
Any direct contact with 110 or 220V wiring has potential for?
electrocution
Red outlets provide what?
emergency power for critical care equipment
Heater/Cooler and Bypass machines can be plugged in same outlet. True or False?
false
GFCI circuit breakers are mainly used for?
outside wiring outlets
What do overcurrent devices do?
protect circuit from excessive heating by opening the circuit in the event of an overload
Static Electricity occur when
static electrical charges accumulate from friction between dissimilar materials; can cause a mild shock
Amps measure
the amount of electric current
Watts measure
the amount off work done by a certain amount of current under a certain pressure
Volts measure
the pressure under which electricity flows
Electric Shock can cause what kind of complications?
vascular injury cardiac arrest eye damage LOC
