About the research
The goal of this clinical trial is to determine whether nasal continuous positive airway pressure (nCPAP) with neurally adjusted ventilatory assist (NAVA) backup ventilation (nCPAP-NAVA-backup mode) reduces the rate of severe apnea in extremely preterm infants ≤28 weeks' gestation compared with standard nasal continuous positive airway pressure (nCPAP mode). Severe apnea episodes is defined as breathing pause with oxygen levels ( SpO2) below 85% lasting at least 5 seconds and/or heart rate (HR) below 100 beats/minute lasting at least 5 seconds.
Each participant will receive both interventions in a randomized order, serving as their own control. The total duration of the intervention will be 24h. Each intervention period will last 12 hours. A washout period of 3 hours will be included between intervention periods to minimize potential carryover effects.
Randomized sequences to avoid order effects:
- Sequence A: nCPAP mode → nCPAP-NAVA-backup mode
- Sequence B: nCPAP-NAVA-backup mode →nCPAP mode
Who may be able to participate?
The list below is the sponsor’s full registry wording. It can include conditions, prior treatment, test results and other requirements. A match in search does not mean you qualify.
Inclusion Criteria:
- Born at ≤28 weeks gestational age
- Currently receiving nCPAP mode as part of routine care
- Receiving caffeine citrate at a maintenance dose of 10 mg/kg/day
- An average of ≥1 severe apnea per hour over a 6-hour period (apnea associated with SpO₂\<85% during ≥ 5 seconds and/or HR \<100 bpm during ≥ 5 seconds) or an average of \>2 severe apnea per hour over a 2-hour period
- Written informed consent obtained from the legal representatives before inclusion.
Exclusion Criteria:
- Major congenital anomalies (e.g., congenital diaphragmatic hernia, significant cardiac malformations)
- Known genetic syndrome affecting respiratory function
- Immediate indication for endotracheal intubation or noninvasive ventilation (NIV)
- Parental refusal or withdrawal of consent
- Previous inclusion in the study
Treatment, groups and participation
The registry may describe treatments and study duration without a complete visit calendar. Ask the study team for the exact schedule, procedures, risks, costs and alternatives. Keep your usual care plan unless your treating clinician tells you otherwise.

Sequence A: nCPAP then nCPAP-NAVA-Backup
Preterm infants randomized to receive 12 hours of standard nCPAP mode followed by 12 hours of nCPAP-NAVA-backup mode (total 24 hours) on a Servo-n ventilator. A 3-hour washout period at the start of each period is excluded from analysis.

Sequence B: nCPAP-NAVA-backup then nCPAP
Preterm infants randomized to receive 12 hours of nCPAP-NAVA-backup mode followed by 12 hours of standard nCPAP mode (total 24 hours) on a Servo-n ventilator. A 3-hour washout period at the start of each period is excluded from analysis.
Device: nCPAP-NAVA-backup mode · Device: nCPAP mode
nCPAP-NAVA-backup mode DEVICE
Standard nasal CPAP delivered via a Servo-n ventilator, with continuous monitoring of the electrical activity of the diaphragm (Edi) through an Edi catheter that also serves as the feeding tube. When an apnea exceeds the preset apnea time, pressure-controlled backup ventilation is triggered automatically. Backup and PEEP settings follow unit standards, and PEEP is kept constant throughout the study. Duration: 12 hours.
nCPAP mode DEVICE
Standard nasal CPAP delivered via nasal prongs or mask on the same Servo-n ventilator and circuit, with PEEP and FiO₂ managed according to standard clinical practice. Duration: 12 hours.
What researchers are measuring
Outcome measures describe what is being studied. They are not proof that a treatment works.
Primary measures
Number of severe apnea episodes per 9-hour observation period
Time frame: Per 9-hour observation period
Number of severe apnea episodes per 9-hour observation period, defined as an apnea associated with oxygen desaturation (SpO₂ \< 85%) lasting ≥ 5 seconds and/or bradycardia (Heart rate (HR) \< 100 bpm) lasting ≥ 5 seconds
Secondary measures
Number of isolated oxygen desaturation episodes
Time frame: Per 9-hour observation period
SpO₂ \< 85% for ≥ 5 seconds, not associated with a severe apnea episode
Number of isolated bradycardia episodes
Time frame: per 9-hour observation period
HR \< 100 bpm for ≥ 5 seconds, not associated with a severe apnea episode
Number of hyperoxia episodes (SpO₂ > 94% for ≥ 5 seconds)
Time frame: per 9-hour observation period
Not reported in this registry record.
Percentage of time spent with SpO₂ < 85%
Time frame: per 9-hour observation period
Not reported in this registry record.
Percentage of time spent with SpO₂ > 94%
Time frame: per 9-hour observation period
Not reported in this registry record.
Percentage of time spent with HR < 100 bpm
Time frame: per 9-hour observation period
Not reported in this registry record.
Number of apnea episodes requiring nurse intervention
Time frame: per 9-hour observation period
tactile stimulation and/or increase in FiO₂
Need for escalation of respiratory support during the observation period
Time frame: per 9-hour observation period
Defined as requirement for transition to non-invasive ventilation mode or endotracheal intubation
Infant comfort assessed using the EDIN score (Échelle Douleur Inconfort Nouveau-Né)
Time frame: per 9-hour observation period
EDIN will be recorded every 3 hours (0-15), yielding up to 3 measurements per 9-hour observation period. The mean EDIN score over each observation period will be used
Gastrointestinal tolerance
Time frame: per 9-hour observation period
Grade 1: good tolerance - enteral feeding maintained at prescribed volume with no significant gastric residuals ; Grade 2: moderate intolerance - enteral feeding volume reduced due to gastric residuals or clinical concern ;Grade 3: poor tolerance - enteral feeding discontinued with initiation of continuous gastric suctioning. The worst grade recorded during each 9-hour observation period will be used as the summary measure for analysis.
