Dialogue:
Doctor: Hello, sir how can I help you? Looks like we are talking about snoring today.
Patient: Yeah, I need to get this loud and obnoxious snoring under control. I keep waking up my partner. I have a C P A P right now because I was told I have almost severe sleep apnea.
Doctor: Yes, I see on your chart that you were given ten centimeters of H two O nasal pressure and that you predominately suffer from hypopnea. Hypopnea is shallow breathing. How has the device been working?
Patient: It definitely has reduced my snoring, but my partner keeps waking me up in the middle of the night because the mask pops off. I wear it around five to seven nights a week, but for some reason it falls off or I take it off randomly in the night. My wife usually must remind me to put it back on.
Doctor: So what is your sleep pattern now? When do you usually go to bed and wake up?
Patient: Usually I sleep around eleven or eleven thirty and wake up at six or seven on the weekends. I'll sleep in until eight or nine on the weekdays. On Saturday's I might go to sleep around midnight because I usually watch a show with my family. I feel good when I wake up though. Much less tossing and turning. The sheets are always on the bed still.
Doctor: That's some good news. I see you have lost a bit of weight too. Around fifteen to eighteen pounds is something to be proud of.
Patient: Thanks. It has been a lot of exercising and dieting. I am motivated because I want to stop snoring.
Doctor: How has work been? Do you think it has been stressful at all?
Patient: I still work at Smith Barney in downtown Baltimore. I work from around eight or eight thirty to five or five thirty. I deal with training on how to sell managed funds and accounts. I do not think I have been stressed because I am able to stay awake through my shift and even when I come home at night. I may get a little tired during hay fever season, but that is rare.
Doctor: Yes, I see that you have hay fever. Fatigue is a common symptom from the allergy.

assistant: The patient initially presented with loud obnoxious snoring that disrupted the sleep of his bed partner. He was found to have moderate-to-severe sleep apnea (predominantly hypopnea), was treated with nasal CPAP at 10 cm H2O nasal pressure. He has been on CPAP now for several months, and returns for followup to review his response to treatment. The patient reports that the CPAP has limited his snoring at night. Occasionally, his bed partner wakes him in the middle of the night, when the mask comes off, and reminds him to replace the mask. The patient estimates that he uses the CPAP approximately 5 to 7 nights per week, and on occasion takes it off and does not replace the mask when he awakens spontaneously in the middle of the night. The patient's sleep pattern consists of going to bed between 11:00 and 11:30 at night and awakening between 6 to 7 a.m. on weekdays. On weekends, he might sleep until 8 to 9 a.m. On Saturday night, he might go to bed approximately mid night. As noted, the patient is not snoring on CPAP. He denies much tossing and turning and does not awaken with the sheets in disarray. He awakens feeling relatively refreshed. In the past few months, the patient has lost between 15 and 18 pounds in combination of dietary and exercise measures. He continues to work at Smith Barney in downtown Baltimore. He generally works from 8 to 8:30 a.m. until approximately 5 to 5:30 p.m. He is involved in training purpose to how to sell managed funds and accounts. The patient reports no change in daytime stamina. He has no difficulty staying awake during the daytime or evening hours. The past medical history is notable for allergic rhinitis.
