Brief Summary
Aim: The purpose of this study is to evaluate the use feasibility of FreeO2 so as to deliver automatically oxygen in the emergency department in a patient population admitted for acute respiratory failure. Hypothesis: The principal hypothesis is that FreeO2 is possible and well-accepted by nurses and medical personnel and there are advantages to use this system. In comparison with the common oxygen delivery (the rotameter), the hypothesis is that FreeO2 system will make for a better control of the oxygen saturation in function of designed target, reducing the desaturation time and hyperoxia. We think that oxygen weaning will be faster than classical way if it is automated. In addition, FreeO2 could reduce the number of intervention by nurse personnel.

Outcome Measures
Primary Outcomes (1)
Percentage of time spent in the target zone of oxygen saturation in the acute phase of treatment
The target zone of oxygen saturation is : SpO2 = 92-96% The "acute phase of treatment" is defined by the 3 first hours of treatment by oxygenation and/or until one hour after the end of this last.
3 hours or 1 hour after after cessation of oxygenation
Secondary Outcomes (7)
nursing workload assessed by the number of manual Oxygen flow adjustments and airway management procedures
3 days max
Time spent in a area of severe desaturation (SpO2 <88%) and a hyperoxia area (SpO2> 98%).
3 hours or 1 hour after after cessation of oxygenation
Maintaining EtCO2 in a selected area
3 hours or 1 hour after after cessation of oxygenation
Oxygen consumption measured at the end of administration
3 hours or 1 hour after after cessation of oxygenation
Duration of administration during hospitalization
28 days max

Eligibility Criteria
You may qualify if:
- Admission to the emergency for respiratory disease (or cardiac - acute pulmonary edema)justifying an oxygen administration to over 3 L / min to maintain a SpO2 ≥ 92%.
- Patient consent,or a close.
You may not qualify if:
- Necessity of an oxygen flow exceeds 15 L / min to maintain a SpO2 higher than 92%.
- Criteria of gravity justifying immediately a different technique of ventilatory support:
- Disturbance of consciousness with a Glasgow Coma Score ≤ 12
- Serious ventricular rhythm disorders
- Hemodynamic instability (SBP \<80mmHg or recourse to vasopressors)

- pH \< 7.35 and PaCO2 \> 55 mm Hg
- Necessity of a urgent surgery, or coronary revascularization
- Age \<18 years
- Pregnant women, lactating
- Patient not relevant
