Preterm Lung Function and Exercise Response Measured by OEP

January 20, 2020 updated by: Newcastle-upon-Tyne Hospitals NHS Trust

Lung Function and Exercise Response Measured by Optoelectronic Plethysmography in School-aged Children Born Preterm

This study will explore lung function and respiratory health in school-aged children who were born prematurely at <32 weeks gestation. It will involve full lung function assessment, a questionnaire and discussion about respiratory health, and an exercise test using optoelectronic plethysmography (OEP) to measure breathing patterns.

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Preterm are born during a critical stage of lung development, and can have abnormalities in lung function that persist with age. Previous studies have shown that children with BPD have reduced lung function and limited exercise capacity. These studies have used conventional lung function testing which requires a tight fitting mask. This is uncomfortable, may alter normal breathing patterns and cannot measure changes in total lung volume.

Optoelectronic plethysmography (OEP) indirectly measures lung volumes and breathing patterns using cameras to track the position of marker stickers on the chest, back and abdomen. It is comfortable, does not require a mask and allows us to track changes in total lung volume.

This study will use standard lung function testing and OEP to measure lung function and breathing patterns at rest and during exercise in school-aged children born prematurely, compared to healthy children born at full term. All participants will complete standard lung function tests, a questionnaire and structured interview to qualitatively assess respiratory health, and an exercise test using OEP to assess how breathing changes with exercise.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in end-expiratory lung volume with exercise
Time Frame: Pre + post exercise (10minutes)
Change in end-expiratory lung volume measured in litres with exercise measured using optoelectronic plethysmography
Pre + post exercise (10minutes)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
