IONM (NIM) System Setup And Signals Interpretation Flashcards
(13 cards)
Bipolar
Low amplitude, fractioned, high frequency EMG signal
100us
Below 0.2
Which muscle activity does the red electrode capture?
Styloglossus, transverse/vertical
**what ahi range is indicated for the genio therapy?
15-65
**what are the 3 main selection criteria for patients receiving genio
1) ahi 15-65
2) refused, not tolerated, or failed cpap
3) less than a 25% mixed and central apnea of the total apnea
What are the recommended electrodes for HGNS implant procedures?
Prass paired with insulation opening, bipolar, 12-18mm (18mm preferred)
When setting up a NIM system, what is the recommended rate and pulse width for the probe?
Rate: 7/s
Pulse: 100us
How many electrodes in total are there and where are they placed?
4 total, 2 pairs. One pair on each side of the Genioglossus muscle, and one pair on each side of the styloglussus/hyoglossus
When do you put the electrodes in the patient’s tongue ?
Before putting on the sterile drape, after intubation
How many mA should you use when identifying the HGN as a whole?
.5-.8
How many mA should you use when identifying inclusionary and exclusionary branches of HGN?
.15-.5
