Repeatability of sites of sleep-induced upper airway obstruction. A 2-night study based on recordings of airway pressure and flow
Abstract
Objectives To evaluate repeatability of overnight continuous airway pressure and flow recordings for assessment of obstructive sites and their distribution in patients with obstructive sleep apnea (OSA). Study design Open, prospective study of 30 men with sleep-induced obstructive events (apnea and hypopnea). Methods Repeated ambulatory sleep recordings of airway pressure and flow to assess the localization of sites of obstructive events were compared. Obstructive sites were divided into upper (transpalatal) or lower (subpalatal). The exact distribution of obstructive sites was expressed as percentage upper obstructive events. A cut-off at apnea index (AI) = 5 was used for comparison between frequent and infrequent obstructers. Results Eighty-two percent (14/17) of patients with frequent, and 58% of those with infrequent apneic events maintained their predominant site of obstructive events classified as upper (transpalatal) or lower (subpalatal) [72% (21/29) in the entire group]. We found a significant correlation between recordings for the percentage upper apneic (R = 0.54, P = 0.024, n = 17) and hypopneic (R = 0.59, P = 0.012, n = 17) events in patients with frequent, but not in those with infrequent apneic events. Patients who had the vast majority of obstructive events located at a single site were more stable than those with more evenly distributed obstructive events. Conclusion Repeatability of sites of obstructive events is influenced by the severity of illness and the…

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
