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

University of Arkansas10 enrolled

Overview

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.

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

Interventions

Effective oxygen delivery and lung expansion measurementDEVICE

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.

Outcomes

Primary Outcomes

Inspired Oxygen

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.

Time frame: Sampling will occur at three separate points within a thirty minute time frame for each enrolled infant.

Secondary Outcomes

Lung Volume

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.

Time frame: Long volume will be continuously monitored throughout the 30 minute duration of the study for each enrolled infant.
