   pulmonary disorders, or any condition with an elevation of arterial carbon dioxide
   levels (>45 mmHG) while awake or participants qualifying for oxygen therapy (arterial
   saturation < or equal to 88% for more than five minutes).

   - Surgery of the upper airway, nose, sinus, or middle ear within the previous 90 days

   - Surgery at any time for the treatment of OSAHS such as uvulopalatopharyngoplasty
