Experimental: High-Flow nasal cannula (HFNC)
Treatment with HFNC will be adjusted for SpO2 >92%, even with FiO2 of 0.21, if needed.
The rationale for this HFNC dosage is that minute ventilation can be already reduced with 30 L/min, but functional residual capacity and oxygenation maximally improve at higher flow. On the contrary, flow >50 L/min is uncomfortable for many patients.
In the case of clinical intolerance, flow will be reduced to 40, 30 or 20 L/min. Yet it is not tolerated, HFNC will be stopped and patients will receive conventional oxygen if required, but will be evaluated as in the HFNC group by intention to treat.
Device: High-Flow nasal cannula (HFNC)
The patient will receive HFNC adjusted for SatO2 > 92% and with, at least, 30 liters of total flow.
Other Name: Conventional therapy
No Intervention: Conventional therapy
Patients assigned to the conventional treatment will receive the standard care given at hospital which consists of adding oxygen on nasal prongs or Venturi mask only if hypoxemia is suggested by SpO2 < 92% by pulse oximetry.
Target for oxygenation in both arms is SpO2 between 92% and 95%. SpO2 >95% without oxygen supply is acceptable. On the contrary, SpO2 <92% may be acceptable when needed for medical reasons, mainly chronic hypercapnic patients.
- Mortality [ Time Frame: 60 day ]60-day survival after enrollment
- Mechanical ventilation support [ Time Frame: up to 60-days ]Institution of mechanical ventilation (either invasive or noninvasive)
- Dialysis support [ Time Frame: up to 60-days ]Institution of dialysis
- Vasoactive drugs tappering [ Time Frame: up to 60-days ]Daily dose of vasoactive drugs until stopping
- Sequential Organ Failure Assessment [ Time Frame: up to 60-days ]Daily Sequential Organ Failure Assessment score. The organs scored are respiratory, cardiovascular, neurologic, hematologic, renal, and liver. Each organ is scored as 0 (best) to 4 (worse) and the total score is the sum of each component.
- Acidosis improvement [ Time Frame: up to 60-days ]Hours until the ph becomes normal
- Central Venous Oxygen Saturation (SatVO2) [ Time Frame: up to 60-days ]Hours until the SatVO2 < 65%
- Lactate clearance [ Time Frame: up to 60-days ]Hours until lactate < 3 mmol/l
