APNEA HRV+SPO2 DATASET

The HuGCDN2014-OXI database was provided by the Dr. Negrín University Hospital (Las Palmas de Gran Canaria, Spain) and contains recordings of 83 subjects, each containing the ECG signal, digitized at 200 Hz, and the SpO2 signal, digitized at 50 Hz. The sleep studies and the labelling process were carried out following the American Academia of Sleep Medicine (AASM) guidelines. An expert labeled every minute based on simultaneous polysomnography, marking it as apnea or nonapnea. There are three groups: 1) CONTROL: thirty-eight (38) healthy subjects with AHIs lower than 5 ranged between (0-5). 2) DESATURATING PATIENTS: thirty-four (34) OSA patients with AHIs higher than 25 ranged between (30-106.3) that show desaturations during apneic episodes. 3) NONDESATURATING PATIENTS: eleven (11) OSA patients with AHIs higher than 25 ranged between (26.2-87.5) that do not always show desaturations during apneic episodes. Patients are defined as nondesaturating when their ODI is less than half their AHI, in our case the 75% of the nondesaturating patients present an ODI less than 7.35 and a total of apneas less than 98, then for 75% of the nondesaturating patients the percentage of desaturating apneic events is below of 7.5%.

HuGCDN2014-OXI数据库由位于西班牙拉斯帕尔马斯-大加那利岛的内格林博士大学医院提供，共收录83名受试者的多模态生理信号记录：每名受试者均包含以200Hz采样率数字化采集的心电图（Electrocardiogram, ECG）信号，以及以50Hz采样率数字化采集的血氧饱和度（SpO2）信号。本数据集的睡眠研究与标注流程均严格遵循美国睡眠医学会（American Academy of Sleep Medicine, AASM）指南，由领域专家基于同步多导睡眠图对每分钟数据进行标注，将其划分为呼吸暂停与非呼吸暂停两类。数据集共分为三组：
1. 对照组（CONTROL）：共计38名健康受试者，其呼吸暂停低通气指数（Apnea-Hypopnea Index, AHI）低于5，取值范围为0~5。
2. 低氧型阻塞性睡眠呼吸暂停患者组（DESATURATING PATIENTS）：共计34名阻塞性睡眠呼吸暂停（Obstructive Sleep Apnea, OSA）患者，其AHI高于25，取值范围为30~106.3，且在呼吸暂停发作期间会出现血氧饱和度降低现象。
3. 非低氧型阻塞性睡眠呼吸暂停患者组（NONDESATURATING PATIENTS）：共计11名阻塞性睡眠呼吸暂停患者，其AHI高于25，取值范围为26.2~87.5，且并非每次呼吸暂停发作均伴随血氧饱和度降低。当患者的氧减饱和度指数（Oxygen Desaturation Index, ODI）低于其AHI的一半时，即被定义为非低氧型患者；本数据集中75%的非低氧型患者的ODI低于7.35，且总呼吸暂停次数少于98次，因此75%的非低氧型患者的低氧性呼吸暂停事件占比低于7.5%。
