Assessing lung function using portable electrical impedance tomography
Pulmonary Function Assessment and Evaluation Using Self-administrable and Portable Electrical Impedance Tomography
Queen Mary Hospital, Hong Kong · NCT05346081
This study is testing if a new portable lung test called electrical impedance tomography can work as a better option than regular lung tests for people with chronic lung diseases.

What this trial studies
This observational study aims to evaluate the feasibility of using electrical impedance tomography (EIT) as an alternative to traditional spirometry for assessing lung function in patients with chronic lung diseases. Participants, aged 18 to 75, will undergo both standard pulmonary function tests and EIT examinations to identify potential biomarkers for monitoring pulmonary conditions. The study will include both patients with pulmonary diseases and healthy controls to compare results and establish the effectiveness of EIT in detecting lung functional changes.
Who should consider this trial
Good fit: Ideal candidates include adults aged 18 to 75 with suspected or diagnosed pulmonary diseases who are scheduled for standard pulmonary function tests.
Not a fit: Patients with implanted electronic devices, unstable cardiac or respiratory conditions, or those unable to perform spirometry may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could provide a more accurate and accessible method for assessing lung function in patients with chronic lung diseases.
How similar studies have performed: While EIT has been used in clinical settings, this specific application for pulmonary function assessment is novel and has not been extensively tested in prior studies.
Eligibility criteria
Show full inclusion / exclusion criteria
Inclusion Criteria: Pulmonary disease subjects Patients of age 18 to 75 suspected or diagnosed with pulmonary diseases scheduled to undergo standard pulmonary function test will be recruited. These patients will undergo an interview (with a structured questionnaire), Pulmonary Functional Test (PFT) and EIT examination. Healthy control subjects Healthy adults of age 18 to 75 who do not have any known pulmonary diseases will be examined. These healthy individuals will undergo spirometry and EIT examination, as well as an interview with a structured questionnaire to ensure they do not have any clinical features or symptoms. Exclusion Criteria: * Subjects with implanted electronic devices, in case EIT might interfere with the devices * Subjects with spinal diseases * Subjects with unstable cardiac or respiratory conditions * Pregnant women * Patients who are unable to perform spirometry
