Electric Surgery Flashcards
What is the greatest patient hazard in electric surgery?
patient burns
Difference between bi-polar and mono-polar
- monopolar: generator-electrode-patient
- ground pad needed*
-bipolar: dispersive not needed, current flows between prongs/blades of instrument and back to generator
Buzzing the hemostat means?
a
Holster questions?
a
placing things on top of ESU unit
a
Things it is safe to do to a grounding path
a
which of the following places makes a safe grounding pad or path site?
a
inactive electrode
a
attachment that does not require grounding pad
a
pediatric and adult settings?
- 30/30 adult
- 17/17 pedi
Thing of concern to OR staff?
a
Know what the term load is?
a
what time of frequency do we use?
200hz-3.3mhz
books (200,000 hz)
household current
60hz
where neuromuscular response stop at one point do we use the ESU
100,000hz
pedi return pads are used on children
a
how to protect self from surgical smoke?
a
What is REM
return electrode monitoring
what do we compare surgical smoke to?
a
what cannot be alternate path to grounding
a
large area of patient comes into contact with dispersive electropad?
a
circuit
the complete path of an electric current, including the generating apparatus, intervening resistors, or capacitors.
conductor
a
current
flow of electrons measured in AMPS
voltage
force or push that moves electrons
frequency
amount of waves moving through a given point at a certain time
hertz
measures frequency
