肺通气功能检查质量数据集

通过采集的患者的呼气曲线的容积、流量和时间采样点数据，提取反应呼气起始、维持、结束过程中受试者行为的特征值，标注每条测试曲线是否可接受以及不可接受原因。利用本数据集可量化受试者检查过程的规范程度，生成质量控制参数和取值界限，并进行验证，实现肺功能FVC 检查实时、智能化质控。

By collecting volumetric, flow, and time-sampled data of patients' expiratory curves, this dataset extracts feature values that reflect the subjects' performance during the initiation, maintenance, and termination phases of exhalation, and annotates each test curve with its acceptability and the corresponding reason for rejection if unacceptable. This dataset enables quantification of the standardization degree of the subjects' examination process, generation of quality control parameters and their value limits, as well as validation of these metrics, thereby realizing real-time and intelligent quality control for pulmonary function FVC (Forced Vital Capacity) examinations.
