Correct Answers
What is the most commonly used light source? - Answer-300 W xenon lamp
What if there is initial low pressure and high flow rate at entry? - Answer-leak in
insufflator circuit, make sure everything is plugged in correctly
What does coagulation mode do? - Answer-rapid surface heating with shallow depth of
necrosis, intermittent wave form with higher voltage
Risks of monopolar - Answer-current can be diverted through unintentional pathways,
leading to inadvertent tissue injury
- don't use hybrid ports that mix metal with plastic
Why do you need a grounding pad for monopolar? - Answer-capacitative coupling -
transfer of energy between two conductors separated by insulator, transfer to passive
electrode. can release with tissue injury but no issue if ground plate working as
capacitor - can't store the charge
Benefits of bipolar energy - Answer-lower energy, producing less lateral tissue damage
and necrosis
- DONT need a grounding pad
Risks of bipolar energy - Answer-risk of cutting patient vessels before adequate sealing,
device doesn't work if metal between the jars
