摘要
背景:多导睡眠图(PSG)是诊断阻塞性睡眠呼吸暂停(OSA)的传统方法,但存在一定的局限性。超宽带雷达(UWB)是结合雷达技术、人工智能(AI)、大数据算法等多种技术的OSA诊断新方法。超宽带在OSA诊断中的准确性有待进一步的科学验证,尤其是在中国南方地区。方法:50例华南地区患者夜间同时佩戴UWB血氧仪和PSG。UWB生成自动报告;PSG是手动解释的。比较两种方法的最低血氧饱和度(LSpO2)和呼吸暂停低通气指数(AHI)。结果:UWB与PSG对AHI (r = 0.925, p < 0.001)、LSpO2 (r = 0.990, p < 0.001)有高度相关性。两种方法的AHI (-3.09, p=0.98, 95% CI -15.48 ~ 9.31)和LSpO2 (-0.34, p= 0.99, 95% CI -3.68 ~ 3.04)的平均偏倚较小。ROC分析显示UWB与PSG的诊断效果较好(AUC = 0.979, p < 0.001),敏感性95.8%,特异性100%。结论:UWB联合血氧测定在中国南方地区可作为诊断OSA的可靠替代方法。
Diagnostic Evaluation of Automatic Noncontact Ultra-Wideband Radar Combined With Oximeter for Obstructive Sleep Apnea in the South of China.
Background: Polysomnography (PSG) is the traditional technique for diagnosing obstructive sleep apnea (OSA) with some limitations. Ultra-wideband radar (UWB) is a new method for diagnosing OSA that combines multiple techniques including radar technology, artificial intelligence (AI), and big data algorithms. The accuracy of UWB in OSA diagnosis needs further scientific verification, especially in southern China. Methods: Fifty patients from southern China wore UWB with oximetry and PSG simultaneously overnight. UWB generated automated reports; PSG was manually interpreted. Lowest oxygen saturation (LSpO2) and apnea-hypopnea index (AHI) from both methods were compared. Results: High correlation was found between UWB and PSG for AHI (r = 0.925, p < 0.001) and LSpO2 (r = 0.990, p < 0.001). The average bias of AHI (-3.09, p=0.98, 95% CI -15.48 - 9.31) and LSpO2 (-0.34, p > 0.99, 95% CI -3.68 - 3.04) between the two methods was small. ROC analysis showed good diagnostic performance of UWB versus PSG (AUC = 0.979, p < 0.001), with 95.8% sensitivity and 100% specificity. Conclusion: The study demonstrated UWB combined with oximetry could be a reliable alternative to PSG for diagnosing OSA in the south of China.
