“…This is also reported by studies on type 3 PM in OSA with and without comorbidities ( 13 , 14 , 18 ). In studies on type 4 PM, though different oximetry devices were performed variously, the newly developed technology with accelerometer and PPG analysis may decrease the disparity between TRT and TST ( 19 , 20 ). However, they were only validated in OSA patients without comorbidities.…”

“…Due to inconvenient movement and limited financial capacity, type 3 PM is a more accessible way to diagnose OSA for polio survivors. Type 4 PM has the advantage of easy set-up and a high success rate, also leading it to be an alternative way to screen OSA for polio survivors ( 19 , 22 ). The results of our current study also provide supportive evidence for the use of type 3 and type 4 PMs.…”

SubjectiveSleep-disordered breathing (SDB) is highly prevalent in polio survivors. Obstructive sleep apnea (OSA) is the most frequent type. Full polysomnography (PSG) is recommended for OSA diagnosis in patients with comorbidities by current practice guidelines, but it is not always accessible. The purpose of this study was to evaluate whether type 3 portable monitor (PM) or type 4 PM might be a viable alternative to PSG for the diagnosis of OSA in postpolio subjects.MethodsA total of 48 community-living polio survivors (39 men and 9 women) with an average age of 54.4 ± 5.3 years referred for the evaluation of OSA and who volunteered to participate were recruited. First, they completed the Epworth Sleepiness Scale (ESS) questionnaire and underwent pulmonary function testing and blood gas tests the day before PSG night. Then, they underwent an overnight in-laboratory PSG with a type 3 PM and type 4 PM recording simultaneously.ResultsThe AHI from PSG, respiratory event index (REI) from type 3 PM, and ODI3 from type 4 PM was 30.27 ± 22.51/h vs. 25.18 ± 19.11/h vs. 18.28 ± 15.13/h, respectively (P < 0.001). For AHI ≥ 5/h, the sensitivity and specificity of REI were 95.45 and 50%, respectively. For AHI ≥ 15/h, the sensitivity and specificity of REI were 87.88% and 93.33%, respectively. The Bland–Altman analysis of REI on PM vs. AHI on PSG showed a mean difference of −5.09 (95% confidence interval [CI]: −7.10, −3.08; P < 0.001) with limits of agreement ranging from −18.67 to 8.49 events/h. ROC curve analysis for patients with REI ≥ 15/h showed an area under the curve (AUC) of 0.97. For AHI ≥ 5/h, the sensitivity and specificity of ODI3 from type 4 PM were 86.36 and 75%, respectively. For patients with AHI ≥ 15/h, the sensitivity was 66.67%, and the specificity was 100%.ConclusionType 3 PM and Type 4 PM could be alternative ways to screen OSA for polio survivors, especially for moderate to severe OSA.

“…PSG tracings were scored manually according to AASM guidelines (Berry et al, 2012). For each participant receiving another three sleep‐monitoring sessions during the study, a wireless, non‐contact, ultra‐wide band (UWB) radar sleep apnea monitor was used to screen for OSA (Li et al, 2023; Zhao et al, 2021; Zhao et al, 2022). The monitor is described in detail in our previous study (Wu et al, 2022).…”

SummaryIn a prospective, randomized, controlled crossover study, we explored the effects of acute intermittent hypoxia and acute continuous hypoxia on patients with mild–moderate obstructive sleep apnea. Over three single‐night sessions, subjects were alternately exposed to normoxia, acute continuous hypoxia and acute intermittent hypoxia before sleep. The apnea–hypopnea index and oxygen desaturation index were used to diagnose obstructive sleep apnea and evaluate efficacy. A responder was defined as a participant with a ≥ 50% reduction in apnea–hypopnea index between normoxia and hypoxia exposure. Sixteen participants with mild–moderate obstructive sleep apnea completed the study. Compared with normoxia, the mean apnea–hypopnea index decreased by 8.9 events per hr (95% confidence interval, 4.2–13.6, p = 0.001) with acute intermittent hypoxia and by 4.1 events per hr (95% confidence interval, 0.5–8.8, p = 0.082) with acute continuous hypoxia, equating to a mean decrease in apnea–hypopnea index of 4.8 events per hr (95% confidence interval, 0.1–9.5, p = 0.046) with acute intermittent hypoxia compared with acute continuous hypoxia. Compared with normoxia, the mean oxygen desaturation index decreased by 9.8 events per hr (95% confidence interval, 4.4–15.1, p = 0.001) with acute intermittent hypoxia but did not significantly decrease with acute continuous hypoxia; the mean oxygen desaturation index decreased by 7.2 events per hr (95% confidence interval, 1.8–12.6, p = 0.010) with acute intermittent hypoxia compared with acute continuous hypoxia. Of the 16 participants, 11 responded to acute intermittent hypoxia and four responded to acute continuous hypoxia (p = 0.032), of whom eight of 11 cases and all four cases had oxygen desaturation indexes <5 events per hr, respectively (p = 0.273). All participants tolerated acute intermittent hypoxia and there were no obvious adverse events during acute intermittent hypoxia exposure. In conclusion, acute intermittent hypoxia exposure improved apnea–hypopnea index and oxygen desaturation index in patients with mild–moderate obstructive sleep apnea, suggesting that further prospective validation of intermittent hypoxia exposure in patients with obstructive sleep apnea is needed to establish its clinical feasibility as a therapeutic modality.

“…While devices based on direct airflow analyses are not often seen, oximetry‐based analyses became more common with the advent of fitness trackers, smartwatches, and rings. The oximeters embedded into wearable devices seem to be accurate in detecting hypoxia in multiple conditions, including during daily life activities, during sleep, and in experimentally induced hypoxia (Jung et al, 2022; Marinari et al, 2022; Santos et al, 2022; Zhao et al, 2022).…”

“…Such innovation seems to arise from a concomitant concern related to inventiveness, patentability, and diagnostic accuracy. Regarding the position of these devices, fingertip oximeters and rings are among the most common (Gu et al, 2020; Zhao et al, 2022), but they also include devices based on neck collars, mandibular movement monitors (Pepin et al, 2022; Pépin et al, 2020), and surface acoustic wave sensors (Jin et al, 2017).…”

Summary There are concerns about the validation and accuracy of currently available consumer sleep technology for sleep‐disordered breathing. The present report provides a background review of existing consumer sleep technologies and discloses the methods and procedures for a systematic review and meta‐analysis of diagnostic test accuracy of these devices and apps for the detection of obstructive sleep apnea and snoring in comparison with polysomnography. The search will be performed in four databases (PubMed, Scopus, Web of Science, and the Cochrane Library). Studies will be selected in two steps, first by an analysis of abstracts followed by full‐text analysis, and two independent reviewers will perform both phases. Primary outcomes include apnea–hypopnea index, respiratory disturbance index, respiratory event index, oxygen desaturation index, and snoring duration for both index and reference tests, as well as the number of true positives, false positives, true negatives, and false negatives for each threshold, as well as for epoch‐by‐epoch and event‐by‐event results, which will be considered for the calculation of surrogate measures (including sensitivity, specificity, and accuracy). Diagnostic test accuracy meta‐analyses will be performed using the Chu and Cole bivariate binomial model. Mean difference meta‐analysis will be performed for continuous outcomes using the DerSimonian and Laird random‐effects model. Analyses will be performed independently for each outcome. Subgroup and sensitivity analyses will evaluate the effects of the types (wearables, nearables, bed sensors, smartphone applications), technologies (e.g., oximeter, microphone, arterial tonometry, accelerometer), the role of manufacturers, and the representativeness of the samples.
