The aim of this study is to evaluate the impact of the FreeO2 system on the quality of the oxygen therapy in confirmed or suspected SARS-CoV-2 patients in the emergency department.
The aim of this study is to evaluate the impact of the FreeO2 system on the quality of the oxygen therapy in confirmed or suspected SARS-CoV-2 patients in the emergency department. The quality of oxygen therapy is evaluated by the time spent in the SpO2 target (+/- 2% SpO2 target), time spent in hyperoxemia (\> 5% SpO2 target), time spent in hyperoxemia (\<5% SpO2 target).

Automated oxygen administration to maintain the SpO2 target at a predefined value during emergency length of stay
Institut Universitaire de Cardiologie et de Pneumologie de Québec-Université Laval
Québec, Canada
Percentage of time in the saturation target in patients on automated oxygen titration device.
The percentage of time in target is defined by the percentage of time of (Target - 3% target) \< SpO2 value \< (Target + 3%) of the selected Spo2 target using automated oxygen titration device.
Time frame: From the initiation of oxygen therapy with FreeO2 until the date of emergency department discharge or Stop of oxygen therapy with FreeO2 whichever came first, assessed up to 3 day after emergency admission
Oxygenation data - hyperoxemia
The percentage of time in hyperoxemia defined as a SpO2 value \> 5% from the target.
Time frame: From the initiation of oxygen therapy with FreeO2 until the date of emergency department discharge or Stop of oxygen therapy with FreeO2 whichever came first, assessed up to 3 day after emergency admission
Oxygenation data - severe hypoxemia
The percentage of time in hypoxemia defined as a SpO2 value \< 85%
Time frame: From the initiation of oxygen therapy with FreeO2 until the date of emergency department discharge or Stop of oxygen therapy with FreeO2 whichever came first, assessed up to 3 day after emergency admission
Oxygenation data - mild hypoxemia
The percentage of time in mild hypoxemia defined as a : (Target - 5% target) \< SpO2 value \< (Target - 2%)
Time frame: From the initiation of oxygen therapy with FreeO2 until the date of emergency department discharge or Stop of oxygen therapy with FreeO2 whichever came first, assessed up to 3 day after emergency admission
automated oxygen therapy duration
Length of total time on automated oxygen therapy in the emergency department in hours.
Time frame: From the initiation of oxygen therapy with FreeO2 until the date of emergency department discharge or Stop of oxygen therapy with FreeO2 whichever came first, assessed up to 3 day after emergency admission

Ventilatory support
Need of change in ventilatory support device : (mechanical ventilation, non-invasive mechanical ventilation, high flow nasal canula, oxygen therapy) during emergency length of stay
Time frame: From the initiation of oxygen therapy with FreeO2 until hospital discharge, assessed up to 2 months after emergency admission
Emergency length of stay.
Time of stay in hours in the emergency department.

Orientation of care
Describe departement admission (emergency observation, general ward ,intensive care unit)
Time frame: From emergency departement admission until the date of hospital discharge assessed up to 2 months after emergency admission
