Brief Summary
The goal of this randomised controlled, cross-over clinical trial is to compare High Flow Nasal Cannulas (HFNC) and Continuous Positive Airways Pressure (CPAP) in neonates over 34 weeks' amenorrhoea (SA) up to children weighing less than 20 kg with respiratory failure. The main question it aims to answer is the non-inferiority of high flows of high-flow nasal cannula compared with CPAP by analysis of diaphragmatic contraction (EAdi (Electrical activity of diaphragm)). Participants with respiratory failure and need of non invasive ventilation and nasogastric tube will receive 4 different increasing flows of HFNC and Positive End-Expiratory Pressure of 7 cmH2O with CPAP during 30 minutes for each flow rate and CPAP. The electrical activity of diaphragm and clinical data of the patient upon each flow and support will be collected. According to the cross-over procedure, the patients will change groups (increasing flows of HFNC or CPAP) in order to perform the remaining analysis.

Outcome Measures
Primary Outcomes (1)
Variations of mean max electrical activity of the diaphragm (mean EAdi) between different HFNC flows and between each HFNC flow and CPAP
Maximal EAdi will be measured in µV
Maximal electrical activity of diaphragm will be recorded every minutes (up to 3 hours)
Secondary Outcomes (10)
Variation in mean minimum EAdi (EAdi min) between different HFNC flows and between each HFNC flow and CPAP
Minimal electrical activity of diaphragm will be recorded every minutes (up to 3 hours)
Variations of heart rate between the different rates of HFNC and between each rate of HFNC and CPAP
every 5 minutes during 3 hours
Variations of respiratory rate between the different rates of HFNC and between each rate of HFNC and CPAP
every 5 minutes during 3 hours
Variations of oxygen saturation between the different rates of HFNC and between each rate of HFNC and CPAP
every 5 minutes during 3 hours
Variations of transcutaneous partial pressure of carbon dioxide between the different rates of HFNC and between each rate of HFNC and CPAP
every 5 minutes during 3 hours
- +5 more secondary outcomes
Study Arms (2)
CPAP-first group
ACTIVE COMPARATORAfter a wash out of 15 minutes with conventional oxygen therapy, CPAP with a Positive End -Expiratory Pressure of 7 cmH2O will be introduced, with an inspiratory oxygen fraction required for an oxygen saturation of 94%, during 30 minutes. The collection of EAdi min/max will be done every minutes over 30min as well as the collection of HR, Respiratory rate (RR), SpO2, while TCPCO2, distress respiratory score and pain score will be taken at M0 and M30.
HFNC-first group
ACTIVE COMPARATORAfter a wash out of 15 minutes with conventional oxygenotherapy, increasing flow rates for up to 2 hours according to the following augmentation: * Initiation at a flow rate of 2 L/kg/min with FiO2 required to achieve SpO2≥94% (increase FiO2 if reliable SpO2 signal \<94% for 1 minute) for 30min. * Increase to 3 L/kg/min after the first 30min of ventilation and repeat the previously described experimental scheme. * Further increase to 4 L/kg/min after 30min of ventilation and repetition of the experimental scheme (if weight \< 16 kg). * Last increase to 5 L/kg/min after 30 min of ventilation and repetition of the experimental scheme (if weight \< 13 kg). The collection of EAdi min/max will be done every minutes over 30min as well as the collection of HR, RR, SpO2, while TCPCO2, distress respiratory score and pain score will be taken at M0 and M30.
Interventions
CPAP and increasing flows of HFNC will be compared during a 30-minutes period each
