Evaluation of automatic titration of oxygen with a new version of FreeO2 (V4)
In the previous studies, the investigators used many times automatic titration of oxygen on spontanous breathing patient (FreeO2 device) with a prototype develop in our lab in collaboration with Laval university. In this study, we want to evaluate the new version of the FreeO2 device (V4)

IUCPQ-UL
Québec, Quebec, Canada
% of time in the set SpO2 target
Continuous SpO2 monitoring (1 data each second) will be recorded, the % of time within the SpO2 target±2% set by the physician will be considered (Time in the target±2/Total recording time)
Time frame: During 3 days of hospitalization or until Oxygen weaning
Oxygenation data
the % of time with hyperoxia (SpO2 \> SpO2 target+5%), the % of time with severe hypoxemia (SpO2 \<85%) the % of time without SpO2 signal, the % of time with oscillations of SpO2 values, comparison of Wired SpO2 vs Bluetooth SpO2, Daily variations of oxygen flows J1, J2 and J3 % Weaning\> 50% relative baseline,% complete weaning of O2
Time frame: 3 hospitalisations day or until Oxygen weaning
