本研究旨在验证新的家庭便携式呼吸器记录装置(PRRD),以识别一组受试者(n = 116)中的睡眠呼吸暂停和低钠,来自一般人群的样本。全夜间夜间创新(PSG)用作黄金标准,并同时用PRRD进行。PRRD测量包括Oronasal气流(热工),胸壁阻抗,氧气饱和度,打鼾和身体位置。传感器对每个记录系统都是唯一的。获得的数据盲目地审查和分析。PSG对PSG和呼吸障碍指数(RDI)之间的方法呼吸暂停/低尿道指数(RDI)之间的高度协议被观察到。根据AHI-PSG> 10和AHI-PSG> 30的不同RDI-PRRD截止点的敏感性和特异性评估PRRD的准确性。进行逻辑回归模型以估计每单位APNOEAS的RDI的机会。绘制了接收的操作特性(ROC)曲线以获得获得的每个观察到的RDI值的灵敏度/特异性分布。来自ROC曲线,作者确定了更好的截止点,代表了平衡的敏感性/特异性。 Through a classification table defined by the cut-off point, the post-odds to exhibit the disease was calculated. For a full PSG cut-off point of 10 a PRRD of six showed a balanced sensitivity of 95% and a specificity of 92%. For a full PSG cut-off point of 30 a PRRD of 16 shows a balanced sensitivity/specificity (100% and 97%, respectively). Post odds of apnoea were calculated for each cut-off point. In conclusion, these data suggest that the portable respiratory recording device is an effective device to identify apnoeas and hypopnoeas in a general population and is therefore a suitable device to be used in epidemiological studies.
