Conditions
Outcome Measures
Primary Outcomes (2)
Upper Airway Collapsability Measures
PhOP - Pharangeal Opening Pressure, the minimum CPAP level needed to have an unobstructed airway
During DISE - during the 20 minutes that the Drug Induced Sleep Endoscopy Occurs.
Upper Airway Collapsability Measures
Pcrit - Critical Pressure, the maximum CPAP level where the airway is obstructed
During DISE - during the 20 minutes that the Drug Induced Sleep Endoscopy Occurs
Secondary Outcomes (1)
Difference in Voltage Requirements
During DISE - During the 20 minutes during which the Drug Induced Sleep Endoscopy occurs
Study Arms (1)
Unilateral vs Bilateral HGNS
EXPERIMENTALAll participants will undergo both unilateral and bilateral hypoglossal nerve stimulation during a single drug-induced sleep endoscopy exam. The voltage will be adjusted \[0.1 5.0 V\].
Interventions
The intervention is testing the effect of unilateral versus bilateral hypoglossal nerve stimulation on upper airway collapsibility during drug-induced sleep endoscopy
