■本研究旨在评估非接触式光纤床垫对呼吸暂停和低通气的诊断价值,并将其与传统的多导睡眠图(PSG)在成人阻塞性睡眠呼吸暂停低通气综合征(OSAHS)中进行比较。
■为了确定用于呼吸暂停和呼吸不足的非接触式光纤床垫的值,从同济医院选择6名健康人和6名OSAHS患者,设计识别呼吸暂停或低通气的方案。共有108例因嗜睡而接受多导睡眠监测的患者,打鼾或其他疑似OSAHS症状。所有108例患者均采用非接触式光纤床垫和PSG进行监测。
■纳入6名健康对照和6名OSAHS患者。六个健康对照的平均呼吸暂停为1.22次/h,6名健康对照者的平均低通气次数为2次/h。在6名OSAHS患者中,平均呼吸暂停12.63次/h,平均呼吸不足为19.25次/h。非接触式光纤床垫结果显示,对照组平均呼吸暂停3.17次/h,对照组平均呼吸不足3.83次/h,OSAHS组平均呼吸暂停11.95次/h,OSAHS组平均呼吸不足17.77次/h。非接触式光纤床垫的呼吸暂停指数与PSG的呼吸暂停指数呈正相关(P<0.05,r=0.835),非接触式光纤床垫的低通气指数与PSG的低通气指数也呈正相关(P<0.05,r=0.959)。非接触式光纤床垫精度高(曲线下面积,AUC=0.889),诊断呼吸暂停的特异性(83.4%)和敏感性(83.3%)。非接触式光纤床垫也具有很高的精度(AUC=0.944),诊断呼吸不足的特异性(83.4%)和敏感性(100%)。在108名患者中,非接触式光纤床垫和多导睡眠监测仪的总记录时间没有显着差异,呼吸暂停低通气指数(AHI),平均心率,心动过速指数,心动过缓指数,最长的呼吸暂停时间,平均呼吸暂停时间,最长的呼吸不足时间,平均呼吸不足时间,总呼吸暂停时间占总睡眠时间的百分比和总呼吸不足时间占总睡眠时间的百分比。非接触式光纤床垫的AHI值与PSG的AHI值呈正相关(P<0.05,r=0.713)。非接触式光纤床垫AHI诊断OSAHS的特异性和敏感性分别为95%和93%,具有较高的OSAHS诊断准确率(AUC=0.984)。
■非接触式光纤床垫用于OSAHS监测的功效与PSG监测没有显着差异。非接触式光学床垫诊断OSAHS的特异性为95%,其敏感性为93%,具有较高的OSAHS诊断准确性。
UNASSIGNED: This study sought to evaluate the diagnostic value of a non-contact optical fiber mattress for apnea and hypopnea and compare it with traditional polysomnography (PSG) in adult obstructive sleep apnea hypopnea syndrome (OSAHS).
UNASSIGNED: To determine the value of a non-contact optical fiber mattress for apnea and hypopnea, six healthy people and six OSAHS patients were selected from Tongji Hospital to design a program to identify apnea or hypopnea. A total of 108 patients who received polysomnography for drowsiness, snoring or other suspected OSAHS symptoms. All 108 patients were monitored with both the non-contact optical fiber mattress and PSG were collected.
UNASSIGNED: Six healthy controls and six patients with OSAHS were included. The mean apnea of the six healthy controls was 1.22 times/h, and the mean hypopnea of the six healthy controls was 2 times/h. Of the six patients with OSAHS, the mean apnea was 12.63 times/h, and the mean hypopnea was 19.25 times/h. The non-contact optical fiber mattress results showed that the mean apnea of the control group was 3.17 times/h and the mean hypopnea of the control group was 3.83 times/h, while the mean apnea of the OSAHS group was 11.95 times/h and the mean hypopnea of the OSAHS group was 17.77 times/h. The apnea index of the non-contact optical fiber mattress was positively correlated with the apnea index of the PSG (P < 0.05, r = 0.835), and the hypopnea index of the non-contact optical fiber mattress was also positively correlated with the hypopnea index of the PSG (P < 0.05, r = 0.959). The non-contact optical fiber mattress had high accuracy (area under curve, AUC = 0.889), specificity (83.4%) and sensitivity (83.3%) for the diagnosis of apnea. The non-contact fiber-optic mattress also had high accuracy (AUC = 0.944), specificity (83.4%) and sensitivity (100%) for the diagnosis of hypopnea. Among the 108 patients enrolled, there was no significant difference between the non-contact optical fiber mattress and the polysomnography monitor in total recording time, apnea hypopnea index (AHI), average heart rate, tachycardia index, bradycardia index, longest time of apnea, average time of apnea, longest time of hypopnea, average time of hypopnea, percentage of total apnea time in total sleep time and percentage of total hypopnea time in total sleep time. The AHI value of the non-contact optical fiber mattress was positively correlated with the AHI value of the PSG (P < 0.05, r = 0.713). The specificity and sensitivity of the non-contact optical fiber mattress AHI in the diagnosis of OSAHS were 95% and 93%, with a high OSAHS diagnostic accuracy (AUC = 0.984).
UNASSIGNED: The efficacy of the non-contact optical fiber mattress for OSAHS monitoring was not significantly different than PSG monitoring. The specificity of the non-contact optical mattress for diagnosing OSAHS was 95% and its sensitivity was 93%, with a high OSAHS diagnostic accuracy.
