Although performed inside a laboratory, attended polysomnography (PSG) has long been the gold standard for the diagnosis of sleep apnea. However, high costs and long wait times have led to the development of home-based portable monitoring devices. A bed sheet-shaped device called SD102 (Suzuken Co., Nagoya, Japan) has been developed, and its accuracy in evaluating sleep apnea is becoming evident. The purpose of this study was to confirm the accuracy of SD102 in evaluating sleep apnea and to investigate patient characteristics that may contribute to inaccurate test results in patients with suspected obstructive sleep apnea (OSA).
One hundred and eighty-nine patients simultaneously underwent PSG and portable monitoring by using a home sleep apnea testing (HSAT) device. A blinded, experienced technologist using the American Academy of Sleep Medicine criteria versions 2.1 and 2.3 scored the PSG data and HSAT device data, respectively.
The respiratory event index (REI) by HSAT significantly correlated with the apnea-hypopnea index (AHI) by PSG (r = 0.974, p < 0.001). HSAT sensitivity, specificity, and positive and negative predictive values of 0.99, 0.83, 0.95, and 0.97, respectively. Body mass index and arousal index were significantly associated with the difference between REI from SD102 HSAT and AHI from PSG.
This study demonstrates the good agreement between REI and AHI in patients with suspected OSA and suggests that understanding the limitations of different testing methods may help in the accurate detection of OSA.
尽管在实验室中进行，但多导睡眠图（PSG）长期以来一直是睡眠呼吸暂停诊断的金标准。然而，高昂的成本和较长的等待时间导致了基于家庭的便携式监测设备的发展。一种名为 SD102（日本名古屋铃木公司）的床单形状的设备已经开发出来，其在评估睡眠呼吸暂停方面的准确性越来越明显。本研究的目的是确认 SD102 在评估睡眠呼吸暂停方面的准确性，并研究可能导致疑似阻塞性睡眠呼吸暂停（OSA）患者测试结果不准确的患者特征。
189 名患者同时接受 PSG 和使用家庭睡眠呼吸暂停测试（HSAT）设备进行便携式监测。一位经验丰富的技术人员使用美国睡眠医学学会标准版本 2.1 和 2.3 对 PSG 数据和 HSAT 设备数据进行盲法评分。
HSAT 的呼吸事件指数（REI）与 PSG 的呼吸暂停低通气指数（AHI）显著相关（r=0.974，p<0.001）。HSAT 的灵敏度、特异性、阳性和阴性预测值分别为 0.99、0.83、0.95 和 0.97。体重指数和觉醒指数与 SD102 HSAT 的 REI 与 PSG 的 AHI 之间的差异显著相关。
本研究表明，在疑似 OSA 患者中，REI 与 AHI 之间具有良好的一致性，并表明了解不同测试方法的局限性可能有助于准确检测 OSA。
