OpenOximetry Repository

The OpenOximetry Repository is a structured database designed to store clinical and laboratory pulse oximetry data and allows for consolidation of data sets held by collaborating organizations. Matched or independent readings of oxygen saturations, arterial blood gas samples, high frequency processed and unprocessed waveforms, and other physiologic metadata are supported (e.g. skin color readings). Contribution of data to the repository is encouraged; a data dictionary and standardized data collection protocols are provided to ensure consistent data archival and interpretation. The goal of this dataset is to enable researchers to interrogate the effects of physiologic and device variables on pulse oximeter performance. A set of controlled desaturation studies is included in the initial release with ongoing updates planned as more data are available from both controlled lab desaturation studies and real world prospective clinical trials. Data captured during these studies may include paired pulse oximeter and arterial blood gas readings throughout a range of oxygen saturations, patient demographics and comorbidities, longitudinal quantitative and qualitative skin color measurement (using multiple methods at multiple anatomic locations), finger diameter, continuous ECG, arterial blood pressure, EtCO2/EtO2, unprocessed photoplethysmography (PPG), pH, PaCO2, hemoglobin, met-Hgb, CO- Hgb, respiratory rate and multiple other variables depending on the data source.开放式血氧计量数据库（OpenOximetry Repository）是一款结构化数据库，旨在存储临床与实验室场景下的脉搏血氧饱和度（pulse oximetry）数据，并支持整合合作机构所持有的数据集。其支持匹配式或独立式血氧饱和度读数、动脉血气（arterial blood gas）样本、高频处理与未处理波形及其他生理元数据（如肤色读数）。本数据库鼓励数据贡献；同时配套提供数据字典与标准化数据采集协议，以保障数据归档与解读的一致性。本数据集的研发目标是助力研究人员探究生理与设备变量对脉搏血氧仪性能的影响。 初始发布版本包含一组控制性去氧饱和研究数据集，后续将根据来自控制性实验室去氧饱和研究与真实世界前瞻性临床试验的新增数据持续更新。上述研究中采集的数据涵盖全血氧饱和度区间内的配对式脉搏血氧仪与动脉血气读数、患者人口统计学特征与合并症信息、多解剖位点多方法下的纵向定量与定性肤色测量数据、手指直径、连续心电图（ECG）、动脉血压、呼气末二氧化碳/呼气末氧分压（EtCO2/EtO2）、未处理光电容积描记图（photoplethysmography, PPG）、pH值、动脉血二氧化碳分压（PaCO2）、血红蛋白、高铁血红蛋白（met-Hgb）、碳氧血红蛋白（CO-Hgb）、呼吸频率及其他依数据来源而定的各类变量。
