Polygraphy after adenotonsillectomy without NIV treatment (A) and under NIV treatment (B) in (A,B), we show extracts from polygraph plot with nasal flux (XFlow), oxygen saturation (SpO2), thoracic and abdominal movements and cardiac pulse. In (A), we see an obstructive breathing pattern with frequent hypopneas characterized by a drop of airflow associated with desaturations >=3% of oxygen. In (B), under NIV, we see a regular breathing pattern with a complete disappearance of obstructive events and desaturation.

Polygraphy under NIV, after 5 days of BPAP support, showed dramatic improvement of OSAS with an obstructive AHI of 7.6/h and only 1% of time with SpO2 < 90% (Figure 1B).
