Pierre Robin syndrome:Necker airway management protocol
• CPAP was started – as a first line therapy in infants with severe UAO– after a (prone position) PG on the following criteria
• AHI >10/h and/or• oxygen desaturation index >15/h and/or • minimal SpO2<90% and/or • maximal PtcCO2>50 mmHg
• CPAP– avoided a tracheotomy in 5/9 patients with severe UAO– normalised sleep in the 4 patients with moderate OSA

Conclusion
• Epidemiology: � use of NIV• Diseases that may require NIV: expanding• Interfaces: interfaces for infants• Compliance: value of specialised centers• CPAP monitoring: few events• NIV/CPAP initiation: future studies should
look for benefit of CPAP/NIV on end-organ morbidity
