StMary Introduction The StMary dataset is Photoplethysmography(PPG) and Respiratory Rate(RR) dataset acquired from surgical intensive care unit(SICU) of Catholic University Seoul St. Mary's Hospital, South Korea. Data Collection The StMary dataset was acquired from a SICU at the hospital using our in-house web application, PPG Signal Collector. Using laptop, we connected a network between the web application and a patient monitor. Through pulse oximeter which connected to the patient monitor, we collected photoplethysmogram of patients and healthy volunteers. Subject's demographic information must be entered before collecting. After that, PPG signal continuously recorded during the time limit we had set and Respiraotry Rate also recorded manually by medical staff pressing spacebar at the exhalation time. The time limit was set up to 2 minutes and 10 seconds. When the time ends, the data is recorded as history and has stored in the database. The collection procedure is as follows: Move into local monitoring page through the browser installed in the laptop. (Set up the measuring time additionally) Register subject’s demographic – gender, age, diagnosis – to start recording. If a window pop-up, click the start button to record PPG. Press spacebar when the subject exhales. When the time outs, the window closed, and the data stored automatically. Data Files The StMary dataset consists of 50 patients and 50 healthy volunteers both aged 18 and older. The dataset has a demographic information, PPG signal and exhalation timestamp for each de-identified subject. 2-minute PPG was collected for each subject twice, and it was sampled into 125Hz. A unique ID is generated for each collected 2-minute PPG. While this ID serves as an identifier for individual data, serving as a de-identifier for the subject at the same time. Patient.csv Diagnosis: Indicates diagnosis of the subject. For volunteers, mark '0'. For patients, name the diagnosis. Gender: Indicates gender of the subject. ("M"/"F") Age: Indicates age of the subject. startMeasureTime: Indicates time when the data starts to move into DB server. endMeasureTime: Measurement ending time. Pleth.csv Timestamp: Indicates time when the PPG at that time collected. Pleth: Indicates PPG which acquired from pulse oximeter.The StMary dataset is Photoplethysmography(PPG) and Respiratory Rate(RR) dataset acquired from surgical intensive care unit(SICU) of Catholic University Seoul St. Mary's Hospital, South Korea. respirationTimeline.csv Timestamp: Indicates time when subject exhales.StMary 数据集简介 本数据集为光电容积描记法(Photoplethysmography, PPG)与呼吸率(Respiratory Rate, RR)数据集，采集自韩国天主教大学首尔圣母医院外科重症监护病房(Surgical Intensive Care Unit, SICU)。 ## 数据采集 本数据集通过自研网页应用程序「PPG信号采集器」于该医院外科重症监护病房完成采集。研究人员借助笔记本电脑搭建该网页应用与患者监护仪的网络连接，通过连接至监护仪的脉搏血氧仪，采集患者与健康志愿者的光电容积描记信号。采集前需录入受试者人口学信息，随后在预设时长内持续记录PPG信号，同时由医护人员在受试者呼气时刻按下空格键手动记录呼吸率。单次采集预设时长为2分10秒，计时结束后，数据将自动存档并存储至数据库。 采集流程如下： 1. 通过笔记本电脑上的浏览器进入本地监测页面（可额外自定义测量时长）； 2. 录入受试者人口学信息——性别、年龄、诊断结果，以启动数据记录； 3. 若弹出操作窗口，点击「开始」按钮即可启动PPG信号采集； 4. 在受试者呼气的瞬间按下空格键； 5. 计时结束后，采集窗口自动关闭，数据将自动完成存储。 ## 数据文件 本数据集包含50名患者与50名年龄≥18岁的健康志愿者的相关数据。每位去标识化的受试者均包含人口学信息、PPG信号与呼气时间戳。每位受试者的2分钟PPG信号被采集两次，采样率设置为125Hz。每一段2分钟的PPG信号均会生成唯一标识符，该标识符既可作为单条数据的唯一标识，同时也可作为受试者的去标识化标识。 各数据文件说明如下： ### Patient.csv - `Diagnosis`：受试者诊断信息。健康志愿者标注为`'0'`，患者则填写具体诊断名称； - `Gender`：受试者性别，取值为`"M"`（男性）或`"F"`（女性）； - `Age`：受试者年龄； - `startMeasureTime`：数据上传至数据库服务器的起始时间； - `endMeasureTime`：测量结束时间。 ### Pleth.csv - `Timestamp`：对应PPG信号的采集时间戳； - `Pleth`：通过脉搏血氧仪采集得到的PPG信号数据。 ### respirationTimeline.csv - `Timestamp`：受试者呼气时刻的时间戳。
