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. All protocol followed were in accordance with the ethical standards of the responsible committee on human experimentation (institutional and national) and with the Helsinki Declaration of 1975, as revised in 2000. All data were anonymized, deidentified and aggregated. This data was approved by the Institutional Review Board of the Ethics Committee of Seoul St. Mary’s Hospital (IRB No. KC21ONSI0839) and the need for consent was waived by IRB.

# 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「PPG信号采集器」于医院SICU内完成采集。研究人员使用笔记本电脑搭建网页应用与患者监护仪之间的网络连接，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。
采集前需先录入受试者的人口统计学信息，随后在预设的采集时长内持续记录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时刻。单次采集时长上限为2分10秒，采集结束后数据将作为历史记录存入数据库。

采集流程如下：
1. 通过笔记本电脑上安装的浏览器进入本地监控页面（可额外设置测量时长）
2. 录入受试者人口统计学信息——包括性别、年龄、诊断结果——以启动记录
3. 若弹出弹窗，点击开始按钮开始记录PPG信号
4. 在受试者呼气时按下空格键
5. 采集时长结束后，窗口自动关闭，数据自动完成存储

## 数据文件
本数据集包含50名患者与50名年龄≥18岁的健康志愿者的数据。每位去标识化受试者均包含人口统计学信息、PPG信号与呼气时间戳。
每位受试者需完成两次2分钟时长的PPG信号采集，采样率为125Hz。每一段2分钟的PPG信号将生成唯一标识符，该标识符既可作为单条数据的标识，同时也可实现受试者的去标识化。

### 各数据文件详情
