Remember initially more than 50% on the ventilators died. This was due to the incorrect high settings used on the machines. That's why some doctors in the US & Italy placed patients in Oxygen helmets and the survival rate increased.For severe and critical patients anything from low doses 1-2 L/min in children and starting at 5 L/min in adults with nasal cannula, with venturi mask (6-10 L/min);or higher flow rates (10-15 L/min) using a mask with reservoir bag.Also oxygen can be delivered at higher flow rates and in higher concentrations, using high-flow nasal cannula (HFNC) devices, non-invasive ventilation (NIV) andinvasive ventilation devices -usually up to >0.4 FiO2/ 30 L/minThis differs across various countries with their own recommendations on covid patient management.PS: The Indian specialists I personally know tells me that they use oxygen only on cases that's really needed and limit to 15 L/min and that's good enough to support them. This is due to the current oxygen shortage and that's what they use for their BPAP, CPAP and NIV as well but raise the FiO2 to 1.0.</blockquote>
