Pressure, flow, and dynamic thoraco-abdominal circumferences data for adults breathing under CPAP therapy

A respiratory pressure, flow, and dynamic circumference (chest and abdominal) dataset was collected from 30 healthy adults at the University of Canterbury under Human Research Ethics Committee (HREC) ethics. Pressure and flow data was collected using a bi-directional Venturi, with data combined in post-collection processing. Dynamic circumferences were measured using inelastic band tape measures attached to rotary encoders capturing expansion and contraction. Data was collected at zero end-expiratory pressure (ZEEP) and with continuous positive airway pressure (CPAP) ventilation, at positive end-expiratory pressure (PEEP) settings of 4 and 8 cmH2O. Data was also collected over three breath types, in which subjects were instructed to breathe normally, to pant as fast as possible, and to breathe as deeply as possible. Recording times were set to 65 seconds for normal and deep breathing, and 35 seconds for panting trials. Subjects self-determined rest time between trials. A questionnaire was used to collect relevant demographic data (sex, height, age, weight, and history of smoking or asthma). The dataset was collected to inform and validate model-based respiratory monitoring systems, with the ultimate goal of shifting respiratory testing from specialist clinical settings to primary care and home settings

一项关于呼吸压力、流量以及动态胸围（胸部和腹部）的数据集，由坎特伯雷大学的30名健康成年人提供，该数据集的收集遵循了人类研究伦理委员会（HREC）的伦理规范。压力和流量数据通过双向文丘里管进行采集，并在数据收集后进行合并处理。动态胸围则通过固定在旋转编码器上的非弹性卷尺进行测量，以捕捉其扩张与收缩。数据在零呼气末压（ZEEP）以及持续气道正压（CPAP）通气条件下，于4和8厘米水柱的正呼气末压（PEEP）设置下进行采集。此外，数据在三种呼吸类型下进行采集，包括正常呼吸、尽可能快地喘息以及尽可能深地呼吸。记录时间分别为正常和深呼吸65秒，喘息试验35秒。受试者在试验间自行决定休息时间。使用问卷收集了相关的人口统计数据（性别、身高、年龄、体重以及吸烟或哮喘病史）。该数据集的收集旨在为基于模型的呼吸监测系统提供信息和验证，其最终目标是实现呼吸测试从专科临床环境向初级保健和家庭环境的转变。
