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.

开放式脉搏血氧仪数据库（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测定（pulse oximetry）数据，同时支持整合合作机构所持有的数据集。该数据库支持血氧饱和度、动脉血气样本、高频处理与未处理波形，以及其他生理元数据（如肤色读数）的配对读数或独立读数。我们鼓励向该数据库贡献数据；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。

初始版本包含一组控制性去氧饱和研究数据，后续将随着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。此类研究中采集的数据涵盖全血氧饱和度区间内的配对脉搏血氧仪与动脉血气读数、患者人口统计数据与合并症信息、多解剖位点多方法下的纵向定量与定性肤色测量结果、手指直径、连续心电图（ECG）、动脉血压、呼气末二氧化碳分压/呼气末氧分压（EtCO2/EtO2）、未处理光电容积描记术（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，以及其他依据数据来源而定的多项变量。
