與醫院睡眠測試/多導睡眠圖相比，倍靈指環的準確度如何？
A diagnostic algorithm combining STOP-Bang cutoff of 5 and bAHI cutoff of 15 events/h demonstrated an accuracy, sensitivity, specificity of 0.938 [95% CI, 0.828–0.987], 0.944 [95% CI, 0.727–0.999], and 0.933 [95% CI, 0.779–0.992], respectively, for the diagnosis of moderate to severe OSA.

倍靈指環睡眠測試後是否需要進行多導睡眠監測？
美國睡眠醫學會 (AASM) 建議對有症狀和無併發症的人群進行家居睡眠測試 (HST)。
如果預測患者 OSA 的可能性較高，且 HST 給出的 AHI > 15，請考慮給予治療方案； 如果患者的 OSA 概率較高，但 HST 給出的 AHI < 5，請考慮安排進一步測試。
Belun Ring does not replace PSG, but offers a convenient and accurate HST for symptomatic screening and treatment evaluation.
倍靈指環如何在沒有呼吸通道（例如氣流和呼吸努力）的情況下確定呼吸暫停/呼吸不足？
Belun’s AI algorithm was trained with >8000 PSG data. The algorithm determines apnea/hypopnea events from the patient’s pattern of SpO2, pulse rate, heart rate variability and motion.
倍靈指環如何在沒有腦電圖的情況下確定睡眠階段和總睡眠時間？
Belun’s AI algorithm was trained with >8000 PSG data. The algorithm determines sleep stage and total sleep time from the patient’s pattern of SpO2, pulse rate, heart rate variability and motion.
倍靈指環如何確定自主神經系統 (ANS) 平衡？
通過身體激活水平的增加，壓力變得可見。 激活水平由自主神經系統 (ANS) 控制，該系統調節胃腸、內分泌、心血管和呼吸系統，以滿足日常生活的需求。 ANS 的兩個部分是交感神經和副交感神經部分。
Parasympathetic nervous system (PNS) restores and maintains the body’s resting condition. Recovery means reduced activation levels in the body in the absence of internal and external stress factors. During recovery, parasympathetic (vagal) activations dominate the ANS and psychophysiological resources are restored. Indicators of recovery include low HR and high HRV.
交感神經系統 (SNS) 幫助身體做好迎接挑戰的準備。 交感神經活動加速身體功能（即生理應激反應）。 應激反應導致應激激素分泌（皮質醇、兒茶酚胺）的激活增加，血壓和心率升高，心率變異性降低。
ANS function can be assessed noninvasively using HR and HRV.
倍靈指環和夜間脈搏血氧儀有什麼區別？
倍靈指環具有額外的通道，包括體動記錄儀和心率變異性，用於確定總睡眠時間，而不是使用記錄時間來計算 ODI 和 AHI。
Standard oximeters cannot determine sleep time and hence underestimate the number of denaturation events per hour.
倍靈指環和消費者腕帶/智能手錶有什麼區別？
Belun Ring is FDA cleared medical device. Accuracy and reliability has been demonstrated to the regulatory body, and also proven in clinical studies.
市場上大部分腕帶和智能手錶都沒有通過準確度要求。 這些消費電子產品提供的數據不能用於臨床應用。
