Feasibility of a Modified Positive Airway Pressure Device to Treat Sleep Disordered Breathing
Feasibility of a Modified Positive Airway Pressure Device to Treat Sleep Disordered Breathing
This study will use a modified version of a positive airway pressure device to supply air to
 the participant, while undergoing supervised polysomnography. Positive airway pressures are
 typically applied to many patients with hypoventilation, in this study these pressures will
 be titrated by a qualified sleep technician. During the night these pressures will be altered
 to optimise comfort.
Inclusion Criteria:

 -  Aged 18+

 -  Patients diagnosed with obesity hypoventilation syndrome (OHS) and/or obstructive
 sleep apnea (OSA) by a practicing sleep or respiratory physician, requiring positive
 airway pressure (PAP) therapy

 Exclusion Criteria:

 -  Recent cardiac or respiratory arrest

 -  Gastro intestinal bleeding, ileus or recent gastrointestinal surgery

 -  Coma, decreased level of consciousness or agitation

 -  Anatomical or subjective difficulty with airway access e.g. facial surgery, trauma,
 vomiting upper airway obstruction

 -  Cerebrospinal fluid leak, abnormalities of the cribiform plate or prior history of
 head trauma.
