Interesting article. Perhaps the use of those nose-bridge
O2 saturating "stickies" may help us sleep better as smoeone
posted here before...Anyone tried it, or willing to try
and report results?

OBJECTIVE: To study subjects with active or inactive cluster headache (CH) for occult sleep
disordered breathing (SDB). BACKGROUND: CH frequently occurs during sleep. The authors
previously found that symptoms of SDB predicted reported occurrence of CH in the first half
of the night, which suggested that CH could be triggered in some cases by unrecognized
SDB. METHODS: The authors performed polysomnography in 25 adults (22 men) with CH.
Subjects were not selected for any sleep-related complaint. In addition to standard measures,
studies included monitoring of end-tidal carbon dioxide (n = 22), and esophageal pressure (n
= 20). RESULTS: The rate of apneas and hypopneas per hour of sleep was >5 in 20 subjects
(80%; 95% CI, 64% to 96%), minimum oxygen saturation was <90% in 10 subjects, maximum
negative esophageal pressure ranged from -13 to -65 cm H2O, and maximum end-tidal
carbon dioxide was > or =50 mm Hg in eight subjects. The eight subjects with active (versus
inactive) CH at the time of study had higher maximum end-tidal carbon dioxide levels (50 +/- 3
versus 44 +/- 5 mm Hg; p = 0.0007). More severe oxygen desaturation was associated with
reports that CH typically occurred in the first half of the nocturnal sleep period (p = 0.008).
CONCLUSIONS: SDB occurred in the majority of patients with CH. Evaluation of a patient with
CH should include consideration that SDB may be present."
