What this Trial Is About
To evaluate the demographic characteristics of normal one-second rates population in patients with pulmonary function tests recommended by outpatient physicians. To investigate whether EIT can identify spatial and temporal heterogeneity of lung ventilation in individuals with normal one-second rates during pulmonary function testing. To investigate the distribution patterns of lung ventilation in individuals with normal one-second rates using this technique, and provide references and evidence for early screening, diagnosis, treatment monitoring, and prognostic evaluation.
