How Different Levels of CPAP Affect Oxygen Delivery and Lung Expansion in Preterm Infants

June 23, 2026 updated by: University of Arkansas

Oxygen Delivery in CPAP and Its Relationship With Regional Lung Ventilation in Preterm Infants

With this study, it is expected to learn more about preterm babies on breathing support with nasal continuous positive airway pressure (nCPAP). To gain more information on how much oxygen is actually delivered to the baby from the nCPAP machine.

Detailed Description

This study will tell more about a specific method of breathing support used frequently with preterm babies called nasal continuous positive airway pressure (nCPAP). It helps the baby breathe by providing air pressure and a certain amount of oxygen. It is very important for the baby's health to provide only as much oxygen as they need.

With this study, it is expected to learn if the amount of oxygen ordered by a doctor on the nCPAP machine changes when it reaches the baby's airway, and if the amount of oxygen changes depending on how much air pressure the doctor provides. The answers to these questions, are not known, because special measurements are required that are difficult to know while a baby is on nCPAP. This study will collect these special measurements

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Infants on nCPAP
All infants on CPAP will have a catheter placed in their oropharynx to measure delivered oxygen and a soft band placed around the infant's chest to measure lung expansion.
Device: Effective oxygen delivery and lung expansion measurement
This intervention arm will involve any infant who is already on nCPAP. It will involve placing a catheter in the infant's oropharynx and wrapping soft EIT bands around the infants chest to measure effective oxygen delivery and lung expansion, respectively.
Other Names:
  • EIT

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Inspired Oxygen
Time Frame: Sampling will occur at three separate points within a thirty minute time frame for each enrolled infant.
Percent of oxygen delivered to the back of the infant's mouth. This will be measured by placing a small plastic tube in the back of the infant's mouth and sampling the air while the infant is receiving several different pressure levels of CPAP.
Sampling will occur at three separate points within a thirty minute time frame for each enrolled infant.

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Lung Volume
Time Frame: Long volume will be continuously monitored throughout the 30 minute duration of the study for each enrolled infant.
Using Electrical Impedance Tomography bands, the infant's lung volume will be monitored at several different CPAP pressure levels. These bands wrap around the infant's chest and measure lung volume using mild electrical currents.
Long volume will be continuously monitored throughout the 30 minute duration of the study for each enrolled infant.

Plan for Individual participant data (IPD)

Plan to Share Individual Participant Data (IPD)?

YES

IPD Plan Description

Coded IPD will be shared with a collaborator once data collection is complete for the purpose of statistical analysis. All shared IPD will be de-identified and individual patients will be given an identifying code. Shared information will include gestational age, date of birth, postnatal age, race/ethnicity, vital signs, prior medical history, current respiratory support, complications during pregnancy, medical problems and diagnoses that the infant receives during hospitalization, and the inspired oxygen and lung volume values gathered during the study itself.

IPD Sharing Time Frame

Beginning once data collection is complete and for three months afterward to afford time for statistical analysis.

IPD Sharing Access Criteria

Only primary investigators will be able to access de-coded IPD. One single collaborator will have access to coded IPD for the purpose of statistical analysis.
