“…Interestingly, personalized sleep diagnostic sensor can provide not only diagnostic but also therapeutic options. One of the therapies that can be successfully used by the patient himself is positional therapy when "positional OSA" occurs [39], [40]. For this reason, a personal sensor needs not only to be a breathing disorders sensor but simultaneously has to assess body position during sleep.…”

This study aims to evaluate the accuracy of a wireless tracheal audio sensor including the sleep body position measurement, as a possible tool to screen for obstructive sleep apnea (OSA) and also to distinguish among "positional" and "non-positional" sleep apnea patients. 30 adult subjects were asked to sleep naturally for a single night in the sleep laboratory, having simultaneous polysomnography (PSG) as a reference. The results were compared using, e.g., Pearson's and Lin's correlation coefficients, Bland-Altman plots, mean absolute error, intercept of the fitted linear model etc. We found the thresholding approach performed on normalized audio energy data achieved mean absolute error of 5.7, and average difference was −2.0. Pearson's and Lin's R coefficients were 0.92 and 0.70, respectively. The qualitative approach reached 86% accuracy (sensitivity of 96%, and specificity of 76%) when setting a binary border at the level of AHI=15 (combined normal + mild versus combined moderate + severe cases). We also checked the distribution of apneas depending on the body position. Our sensor showed a mean ± SE difference between supine apnea index and non-supine apnea index of 8.3 ± 3.2, while PSG reference of 11.2 ± 3.8. The proposed sensor might be a good complement for home sleep studies, being less disturbing and allowing for longitudinal observations and reliably showing positional OSA. PSG is the gold standard in diagnosing OSA; however, it requires to spend a night in a lab with medical staff, it provides short observation, the cost of the study is very high, and it is less suitable for children. This is why a reliable screening method is needed in sleep medicine.

“…Der Begriff "rückenlageabhängige obstruktive Schlafapnoe" wird üblicherweise verwendet, wenn der AHI in Rückenlage mindestens doppelt so hoch ist wie in den übrigen Lagen [51] "tennis-ball technique", sowie spezielle Kissen und Rucksäcken) und aktiven Verfahren (Lagetrainer, Vibrationsalarm gesteuert durch speziellen Algorithmus) unterschieden werden [52]. Analog zu anderen Hilfsmitteln ergibt sich auch hier das Problem der Compliance.…”

“…Hierbei gilt es jedoch zu beachten, dass es sich hauptsächlich nur um ein System in diesen Metaanalysen handelte. Zwei von diesen Studien zeigten, dass CPAP eine stärkere Reduktion des AHI mit einer mittleren Differenz von 6,4 Ereignissen pro Stunde (95 % CI 3,00 bis 9,79) im Vergleich zur Lagetherapie ergab [52]. Positive Effekte auf die Tagesschläfrigkeit waren unter Lagetherapie und CPAP vergleichbar [52].…”

Background: Evaluation and interpretation of the literature on obstructive sleep apnea (OSA) allows for consolidation and determination of the key factors important for clinical management of the adult OSA patient. Toward this goal, an international collaborative of multidisciplinary experts in sleep apnea evaluation and treatment have produced the International Consensus statement on Obstructive Sleep Apnea (ICS:OSA). Methods: Using previously defined methodology, focal topics in OSA were assigned as literature review (LR), evidence-based review (EBR), or evidencebased review with recommendations (EBR-R) formats. Each topic incorporated the available and relevant evidence which was summarized and graded on study quality. Each topic and section underwent iterative review and the ICS:OSA was created and reviewed by all authors for consensus. Results: The ICS:OSA addresses OSA syndrome definitions, pathophysiology, epidemiology, risk factors for disease, screening methods, diagnostic testing types, multiple treatment modalities, and effects of OSA treatment on multiple OSA-associated comorbidities. Specific focus on outcomes with positive airway pressure (PAP) and surgical treatments were evaluated. Conclusion:This review of the literature consolidates the available knowledge and identifies the limitations of the current evidence on OSA. This effort aims to create a resource for OSA evidence-based practice and identify future research needs. Knowledge gaps and research opportunities include improving the metrics of OSA disease, determining the optimal OSA screening paradigms, developing strategies for PAP adherence and longitudinal care, enhancing selection of PAP alternatives and surgery, understanding health risk outcomes, and translating evidence into individualized approaches to therapy.
