About this study

Official title: The Associations Between EIT and Clinical Measures During Standard of Care Procedures in Patients With Respiratory Disease: A Preliminary Study

The purpose of this study is to evaluate the Genesis Electrical Impedance Tomography (EIT) imaging system for use in pediatric respiratory disease populations including neuromuscular and bronchopulmonary dysplasia, as well as in age and height matched controls. The EIT does not use radiation, and is read through electrodes.

Read the detailed description

The purpose of this study is to evaluate EIT for use in pediatric respiratory disease populations including neuromuscular and bronchopulmonary dysplasia, as well as in age and height matched controls.

Researchers will use EIT to determine changes in regional ventilation with pulmonary interventions including airway clearance and invasive and noninvasive ventilation in a pediatric respiratory disease population.

Premature Birth, Neuromuscular Diseases, Bronchopulmonary Dysplasia, Stenosis, Pulmonary Vein

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

Study groups in NCT03797183
Study groupRoleWhat they receive
Premature InfantsPremature infants >1 month of age currently hospitalized with bronchopulmonary dysplasia (BPD) without acute respiratory infection
Chronic Respiratory DiseaseParticipants ages >1 month-21 years with chronic respiratory disease due to underlying neuromuscular disease
Neuromuscular DiseaseParticipants ages 21-40 years with confirmed neuromuscular disease with an echo completed within the preceding 12 months of study participation of Duchenne muscular dystrophy (DMD) or other diagnoses associated with mild cardiomyopathy
Healthy ControlsAge and height matched healthy controls
V/Q Scan validationAdults or children who are having or have recently had a V/Q scan
Premature Infants (Longitudinal Cohort)Premature infants ages 2 weeks to 1 year with diagnosed or suspected bronchopulmonary dysplasia
Pulmonary Vein/Artery StenosisChildren age 2 months to 18 years, who will be undergoing cardiac catheterization for pulmonary vein stenosis, pulmonary hypertension and/or pulmonary artery stenosis

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. EIT imaging maps that provide regional information regarding ventilation and perfusion of the lung.

    These images will be analyzed both visually for qualitative abnormalities and through quantitative pixel analysis that can provide information regarding lung volume, blood volume, and changes in either based on respiratory cycle, cardiac cycle, or intervention. Areas of low ventilation (atelectasis and consolidation) will be identified.

    Measured: 24 months

Secondary outcomes (5)
  1. Regional conductivity changes due to ventilation

    Describe regional ventilation in pediatric respiratory disease populations including neuromuscular weakness, skeletal/chest wall disorders, and chronic airway and parenchymal lung disease including bronchopulmonary dysplasia.

    This is a qualitative aim and will summarize EIT images pictorially. Pixel densities will be evaluated for normality and summarized as mean (SD) or median (interquartile range). EIT images will be qualitatively compared between cases and controls.

    Measured: 24 months

  2. Waveform for a mesh element

    Time-series waveform indicated by time in seconds compared to Recon signal (au).

    Measured: 24 months

  3. Regional conductivity changes due to perfusion

    This is a qualitative and quantitative aim. Results will qualitatively compare EIT images with CXR and CT scan images when available. Images will be displayed side by side and interpreted by both the clinician and the EIT study staff. Various summary measures of EIT outcomes will be calculated including pixel heterogeneity, summary changes over tidal breath and variation between tidal peaks. Pearson and Spearman correlation will be calculated between summary EIT outcomes and continuous primary clinical values. Linear and logistic regression will be used to estimate associations (with 95% CI) between EIT measures and clinical outcomes. Summary data will be presented in tables and figures using basic descriptive statistics stratified by study group.

    Measured: 24 months

  4. Regional pulsatile perfusion imaging at the end of systole

    Measured: 5 minutes

  5. Power waveform (computed as the inner product of measured voltages and applied currents)

    Measured: 24 months

Questions about this trial

What is this clinical trial studying?

An observational study of Premature Infant and Chronic Respiratory Disease, run by University of Colorado, Denver at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 13 Nov 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Emily DeBoer, MD (720-777-4953, emily.deboer@childrenscolorado.org), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

EIT imaging maps that provide regional information regarding ventilation and perfusion of the lung. (time frame: 24 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Nov 2025.
