About this study

To evaluate feasibility of photoplethysmography (PPG) of pulmonary arteries in adults children and neonates and to compare normal controls to premature newborns suffering from patent ductus arteriosus and neonates suffering from pulmonary hypertension.

Read the detailed description

This study aims to check a new device for measuring lung photoplethysmography (PPG) of pulmonary arteries by delivering light through the chest wall. The aim is to evaluate pulmonary arteries' elasticity and oxygen saturation.

We will study adults children and neonates. We will study 20 healthy adults, 20 healthy children aged 2-8 years, twenty healthy neonates, 20 preterm neonates with patent ductus arteriosus (PDA) and 20 preterm neonates with no PDA. We will study also 20 neonates with pulmonary hypertension.

Each participant will be examined for 5 minutes and PPG signal will be recorded in a computer and evaluated offline later on. Pulmonic saturation will be calculated from absorption difference between two wave lengths of infrared light that will be used.

Our hypothesis is that the mentioned clinical conditions will affect PPG signal and pulmonary arterial oxygen saturation.

Questions about this trial

What is this clinical trial studying?

An observational study of Patent Ductus Arteriosus and Pulmonary Hypertension, run by Shaare Zedek Medical Center.

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 1 inclusion and 1 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: status not confirmed, as of the sponsor's last update on 9 Sep 2016. Status can change between updates, so confirm with the study contact before making plans.

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?

Results are not available in the source record.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

difference in PPG or pulmonary saturation between conditions (time frame: 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02894970, which also lists 1 linked publication.

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 9 Sep 2016; AzTrials last refreshed its copy on 8 Nov 2026.
