Automatic Administration of Oxygen During Respiratory Distress

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.
