摘要:
Methods and apparatus provide Cheyne-Stokes respiration ("CSR") detection based on a blood gas measurements such as oximetry. In some embodiments, a duration, such as a mean duration of contiguous periods of changing saturation or re- saturation occurring in an epoch taken from a processed oximetry signal, is determined. An occurrence of CSR may be detected from a comparison of the duration and a threshold derived to differentiate saturation changes due to CSR respiration and saturation changes due to obstructive sleep apnea. The threshold may be a discriminant function derived as a classifier by an automated training method. The discriminant function may be further implemented to characterize the epoch for CSR based on a frequency analysis of the oximetry data. Distance from the discriminant function may be utilized to generate probability values for the CSR detection.
摘要(中):
方法和装置基于血气测量(例如血氧定量法)提供Cheyne-Stokes呼吸(“CSR”)检测。 在一些实施例中,确定持续时间,例如在从经处理的血氧测定信号取得的时期中发生的改变饱和度或再饱和的连续周期的平均持续时间。 可以从持续时间和导出的阈值的比较来检测CSR的发生,以区分由于呼吸呼吸引起的饱和度变化和由于阻塞性睡眠呼吸暂停引起的饱和度变化。 阈值可以是通过自动训练方法作为分类器导出的判别函数。 基于氧饱和度数据的频率分析,可以进一步实现判别函数以表征CSR历元。 可以利用与判别函数的距离来生成CSR检测的概率值。
