Summary

The standard for treatment for people suffering from obstructive sleep apnea (OSA) syndrome involves the use of Continuous, or Automatic Positive Airway Pressure (CPAP, APAP) machines, which work by delivering air via tubing and mask to a patient at pressures of up to 20cmH2O. This increased pressure is meant to stabilize the airway to reduce obstruction events. APAP machines are generally more effective and more comfortable for patients than CPAP machines because these devices automatically adjust pressure to treat an apnea. As a result of the high rate of patient dissatisfaction with conventional PAP therapy, alternative treatments for sleep apnea have been developed. One therapeutic target for OSA is stimulation of the genioglossus muscle, a phasic respiratory muscle important in maintaining upper airway patency.

Recently, it has been shown that genioglossus reflex responses can be achieved through the application of negative pressure pulses as well as changes in airway pressure. These studies focused on activating pressure-sensitive mechanoreceptors within the upper airway known to contribute to genioglossus activity. Together, these studies have demonstrated that both brief pulses of negative airway pressure and changes in airway pressure are capable of eliciting genioglossus reflex responses.

The goal of this interventional study is to evaluate the potential of airway muscle activation on sleep-disordered breathing during sleep therapy by applying brief maneuvers of air pressure using existing pressure and flow sensors in conventional CPAP machines.

DEVICE

NovaResp MAPR System

Baseline measurements will be taken while the subject is awake. Genioglossus activity with maximal tongue protrusion will be measured as well as the response to 1 to 2 pressure routines. Once the subject is sleeping, the operator will observe the PSG recording and determine sleep stage and respiratory phase (inspiration, expiration, between breaths). Test routines will be performed for each sleep stage and each respiratory phase. If the operator notices an apnea occurring, one of the routines will be applied. When all manual tests are complete, an "automatic" mode will be engaged for the remainder of the night. During this mode, a previously developed and trialled AI model will be used to predict if an obstructive apnea is upcoming. The operator will input which routine to test, and the routine will be automatically applied when a prediction occurs. There will be a minimum of 60 seconds between pressure routine applications.
