NIV NAVA Versus NIV-PS in Pediatric Patients - Pilot Study

Neurally Adjusted Ventilatory Assist (NAVA) Versus Pressure Support in Pediatric Acute Respiratory Failure - Pilot Study

This pilot study will be an observational no randomize study in which the NiNAVAped protocol will be applied solely to the NIV NAVA arm.

This pilot study will be an observational no randomize study in which the NiNAVAped protocol will be applied solely to the NIV NAVA arm.

Every PICU will have to include 3 patients in the Pilot study before starting the clinical trial, which means that the pilot study will involve a maximum of 60 patients.

Should the Pilot study reveal deficiencies in the NiNAVAped design, the protocol would be improved accordingly.

There will be a specific consent document during the Pilot study. The Pilot study will be published in a scientific journal.

Inclusion Criteria:

• Age: > 1 month age to 18 years
• Moderate/severe Pediatric Acute Respiratory failure of any origin evaluated after a period of respiratory stabilization (aspiration of secretions, physiotherapy, oxygen and nebulized therapy) when the attending pediatric intensive care physician believes that the patient is likely to require endotracheal intubation (ETI).
• Non intubated
