Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this clinical trial is to compare late preterm newborn lung physiology when supported with different continuous positive airway pressure (CPAP) devices.

The main questions it aims to answer are:

* Which CPAP modality provides better breathing support in newborns with respiratory distress syndrome who are greater than 32 weeks gestational age?
* Does the lung physiology data predict the CPAP modality that will result in a shorter CPAP treatment duration?

Participants will wear a belt of electrodes on their chest (electrical impedance tomography) and have an esophageal balloon manometry measure lung physiology data for 2.5 hours while switching CPAP devices. Participants will then be randomly assigned to a CPAP device to support their breathing until they recover from respiratory distress syndrome.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Across centers, there is a variation in standard of care for the preferred device and interface to deliver continuous positive airway pressure (CPAP) to support neonatal functional residual capacity. CPAP, a type of noninvasive respiratory support, is commonly delivered to neonates by mechanical ventilators or underwater bubble devices (bubble CPAP). Variation also exists with the tubing used to deliver CPAP. One commonly used nasal interface is the RAM cannula (Neotech, Valencia, CA), made of a soft material with thin tubing walls and is designed to provide 60-80% occlusion of the nares. This contrasts with the occlusive interface intended to provide complete seal.

To provide evidence for standardization of CPAP delivery, clinical trials are needed to assess which modality of CPAP delivery is optimal for neonates with respiratory distress syndrome who are \> 32 weeks and \<37 weeks gestational age, an understudied population. The investigators propose to use electrical impedance tomography (EIT) paired with esophageal balloon manometry to assess neonatal lung physiology when supported with different modalities of CPAP. Furthermore, participants will be randomly assigned to A) physiology based CPAP vs B) one size fits all approach. The subjects will remain on the assigned modality of CPAP for the remainder of their respiratory distress syndrome treatment, and researchers will track which modality of CPAP results in a shorter CPAP treatment period and if this is expected based on the lung physiology data collected.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

Lung physiology measurements with electrical impedance tomography and esophageal manometry will be collected while the participant is supported with RAM cannula ventilator CPAP followed by occlusive interface ventilator CPAP followed by occlusive interface bubble CPAP. A 1:1 block randomization of either A) physiology-based CPAP or B) one size fits all CPAP of either RAM cannula ventilator CPAP or occlusive interface bubble CPAP will be assigned to the participant. Arm B is further randomized 1:1 to either RAM cannula ventilator CPAP or occlusive interface bubble CPAP. The duration of CPAP treatment will be compared between the two arms (precision medicine approach vs standard of care) as well as compare each device and whether the physiology data would have predicted the CPAP device would have resulted in a shorter treatment period.

Blinding Strategy

TRIPLE

Participants Caregivers Outcome Assessors
Given the nature of CPAP, it is not possible to mask which CPAP device the subject is supported by, but the participant, care provider, and outcomes assessor will be masked to whether the subject was randomized to arm A (the device the lung physiology assessment deemed superior for that subject) or arm B (random assignment to the CPAP device, not taking into account the subject's lung physiology).

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Randomization to CPAP with higher change of impedance as measured by EIT. "Arm A-1"

After comparing change of impedance as measured by electrical impedance tomography while supported on RAM cannula ventilator CPAP versus occlusive interface bubble CPAP, the participants in this arm are placed on the CPAP that had a greater change of impedance (or less pressure rate product as measured by the esophageal balloon manometry if the change of impedance between the two CPAP modalities are clinically similar).

In this Arm A-1, these subjects had higher change in impedance while supported on RAM cannula ventilator CPAP

Randomization to standard of care - a 'one size fits all' approach. "Arm B-1"

Currently, the approach to which CPAP modality is chosen for these newborns is defaulted to the preferred CPAP of the Neonatal Intensive Care Unit (NICU) where the newborn is hospitalized.

In this Arm B-1, these subjects are randomized 1:1 to RAM cannula ventilator CPAP

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* medically stable neonates born \>32 0/7 weeks and \< 37 0/7 weeks gestational age, with birth weights \> 1500 grams, are chronologically 12-36 hours old, and are receiving RAM cannula ventilator CPAP with positive end expiratory pressure (PEEP) between 5-6 cm water (H2O) and Fraction of inspired oxygen (FiO2) \< 0.3 for the suspected diagnosis of respiratory distress syndrome

Exclusion Criteria

* neonates with congenital anomalies that potentially will affect respiratory physiology, for example hypoplastic lungs or gastroschisis.
* neonates with contraindications for wearing an occlusive interface, for example epidermolysis bullosa which may have risk of worsening skin integrity at the pressure points of the occlusive interface, or a known small air leak that may potentially develop into a large pneumothorax.
* neonates with contraindications for placement of esophageal balloon manometry, for example hypoglycemia managed with extended feeding times greater than 30 minutes.
* neonates with contraindications for electrical impedance tomography, for example inability to ensure contact of the electrodes on the belt with the skin on the circumference of the chest due to presence of a chest tube dressing.
