Eight-Week PAP Follow-Up: Claustrophobia, Congestion, and a Rotating Shift
Mr. R is a 44-year-old warehouse supervisor who rotates between two weeks of day shift and two weeks of night shift (7 p.m. to 7 a.m.). He was diagnosed with obstructive sleep apnea (AHI 38) eight weeks ago and started autotitrating PAP with a nasal mask. The 30-day device report shows a nightly average of 3.1 hours, use on 48% of nights, residual AHI 6, and large leak on 22% of nights. He reports tearing the mask off about 3 a.m. because he feels "closed in," wakes with a dry mouth and a blocked nose, and has never used the humidifier. He has used an over-the-counter decongestant spray every night for about two years. Epworth score is 14. He tells you, "I gave the machine a fair shot. I want the surgery instead."
1. Which findings in this case are the highest-yield targets for intervention, and in what order would you address them? Justify the sequencing.

Reason from cause to effect rather than from the complaint.
- Nasal obstruction and rebound congestion. Two years of nightly topical decongestant strongly suggests rhinitis medicamentosa. A blocked nose drives mouth leak (dry mouth, 22% large leak) and mouth leak drives mask discomfort and arousals. This is upstream of almost everything else.
- No humidification. Adding heated humidification is low-cost and directly targets dryness and mucosal irritation.
- Interface and desensitization. The "closed in" sensation is treatable with a smaller-footprint interface trial, fitting with the patient awake and seated, and graded mask-on time while awake.
- Shift timing. Sleep opportunity should be anchored to the day/night rotation; on night-shift weeks, PAP use should begin at the main sleep block, not at nap attempts.
- Leak and residual AHI are rechecked only after 1-4 are addressed, because fixing them changes both numbers.
Surgery is a reasonable conversation later, but he is describing a fixable interface/side-effect problem, not a device failure - treat it as such first.
2. How would you respond to his request for surgery instead of PAP, using his own data?

Do not argue about willpower and do not promise a cure from surgery.
- Anchor on his goal: feeling awake at work during a 7 p.m. to 7 a.m. rotation. Sleepiness on a night shift is a safety issue, not a comfort issue.
- Use his numbers plainly: he is averaging about 3 hours and using it on fewer than half of nights, so the trial so far has not tested whether PAP works for him - it has tested whether an untreated blocked nose and a mask he dislikes can work.
- Be honest that upper airway surgery is generally adjunctive, has variable and often incomplete effect on AHI, and is not reliably curative; it may be considered for specific anatomy after a proper PAP trial. If he wants that pathway, it should be discussed with the sleep physician, not chosen as an escape from a fixable side effect.
- Frame the next 3-4 weeks as a defined experiment: congestion plan plus humidification plus an interface trial, with a stated recheck date. Giving him a concrete endpoint respects his autonomy better than a lecture.
3. What would you document from this encounter?
Read the worked answer
Document objectively and in a way that a physician, payer, or future educator could reconstruct the visit:
- Device data as reported: 30-day average 3.1 h, 48% of nights used, residual AHI 6, large leak 22% of nights.
- Patient-reported symptoms in his words: claustrophobia, mask removal around 3 a.m., dry mouth, nasal blockage.
- Objective findings: long-term nightly decongestant spray use; no humidifier use; Epworth 14.
- Education delivered: rhinitis medicamentosa explanation and taper plan, heated humidification instructions, interface trial options, shift-anchored sleep scheduling, surgery versus PAP discussion.
- Patient response and goals, including that he asked about surgery.
- Plan and follow-up date, plus what will be reviewed at that visit (adherence, leak, residual AHI, nasal symptoms).
Avoid conclusions the data do not support, such as "noncompliant patient" - describe behaviors and their causes.
