About this study
Official title: Diaphragmatic Activity During Constant or Variable Flow CPAP in Neonates: a Non-inferiority, Randomized, Alternating Treatments Trial
The hypothesis behind the study is that the performance of constant flow CPAP (Continuous Positive Airway Pressure) devices (CF-CPAP) is not inferior to that of variable flow CPAP devices (VF-CPAP) in terms of respiratory efforts assessed by swing EAdi (Electrical activity of diaphragm) in a population of premature neonates born ≤ 32 weeks of gestational age.
Read the detailed description
CPAP is an indispensable tool in NICU (neonatal intensive care unit ) to recruit and maintain lung volume, to reduce airway resistances and increase pulmonary compliance. However, the variety of existing pressure generators (constant-flow=CF-CPAP or variable flow=VF-CPAP) and interfaces (prongs, masks) makes evidence-based clinical decisions difficult. Considering the persisting controversy regarding the comparative efficacy of CF-CPAP versus VF-CPAP, new less- or non-invasive tools such diaphragmatic electrical activity (EAdi) monitoring may allow to better evaluate their impact on respiratory efforts.
Our hypothesis is that CF-CPAP devices with nasal mask are not inferior to VF-CPAP devices with nasal mask regarding respiratory efforts assessed by observed swing EAdi in a population of neonates born at ≤ 32 weeks gestational age.

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 16 inclusion and 0 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: looking for participants now, as of the sponsor's last update on 23 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.
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?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Xavier DURRMEYER, MD, PhD (0157023468, Durrmeyer.xavier@chicreteil.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Mean swing EAdi (µV) (time frame: Continuous recording during 1 hour and 30 minutes after a 30 minutes wash-out period for each ventilation period). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 23 Jun 2026.
