Study Arms:
- nHFOV (Type: EXPERIMENTAL): Immediately after extubation, nHFOV is provided via binasal prongs. Ventilator settings: Frequency set at 10 Hz, I:E ratio 33:66, amplitude 20 cm H2O, Pmean 8 cm H2O, flow 7 l/min. Set FiO2 to maintain SpO2 at 90-94%.~The weaning process is left to the discretion of the attending physician. Maximum amplitude 30 cm H2O, minimum frequency 9 Hz, maximum Pmean 8 cm H2O.~For infants in the nHFOV-group who fail nHFOV (see definition below), but do not need immediate reintubation, a non-invasive Rescue-Treatment may be provided. The decision to attempt Rescue-Treatment, the mode of respiratory support and the ventilator settings used are at the discretion of the attending clinician.
- nCPAP (Type: ACTIVE_COMPARATOR): Immediately after extubation, nCPAP is provided via binasal prongs. Ventilator settings: CPAP level set at 8 cm H2O, flow 7 l/min. Set FiO2 to maintain SpO2 at 90-94%.~The weaning process is left to the discretion of the attending physician. Maximum CPAP level 8 cm H2O, maximum flow 8 l/min.~For infants in the nCPAP-group who fail nCPAP (see definition below), but do not need immediate reintubation, Rescue-nHFOV via binasal prongs may be provided. The decision to attempt Rescue-nHFOV and the ventilator settings used are at the discretion of the attending clinician.

Based on this trial design, predict the completion outcome and termination type (if applicable).
