Monitoring mandibular movements to detect Cheyne-Stokes Breathing.

摘要: The patterns of mandibular movements (MM) during sleep can be used to identify increased respiratory effort periodic large-amplitude MM (LPM), and cortical arousals associated with “sharp” (SPM). We hypothesized that Cheyne Stokes breathing (CSB) may identified by abnormal patterns. present study aims evaluate prospectively the concordance between CSB detected polysomnography (PSG) as gold-standard. In 573 consecutive patients attending an in-laboratory PSG for suspected disordered (SDB), signals were acquired using magnetometry scored manually while blinded from signal. Data analysis aimed verify presence LPM or SPM. data randomly divided into training validation sets (985 5-min segments/set) was evaluated 2 classification models. PSG, 22 (mean age ± SD: 65.9 ± 15.0 a sex ratio M/F 17/5) had central apnea hourly indice ± SD: 17.5 ± 6.2) total SDB. When tested on independent subset, based SPM is highly accurate (Balanced-accuracy = 0.922, sensitivity = 0.922, specificity = 0.921 error-rate = 0.078). Logistic models odds-ratios in 172.43 (95% CI: 88.23–365.04; p < 0.001) 186.79 100.48–379.93; p < 0.001), respectively. could accurately simple magnetometer device recording movements.
