Difference in PaO(2)/FiO(2) between high-flow nasal cannula and Venturi mask in hypoxemic COVID-19 patients

The ratio between arterial blood partial pressure of oxygen and fraction of inspired oxygen (PaO(2)/FiO(2)) was largely used for grading and managing the respiratory failure in non-mechanically ventilated COVID-19. In these patients, the assessment of the true FiO(2) in the inspired mixture may be d...

description The ratio between arterial blood partial pressure of oxygen and fraction of inspired oxygen (PaO(2)/FiO(2)) was largely used for grading and managing the respiratory failure in non-mechanically ventilated COVID-19. In these patients, the assessment of the true FiO(2) in the inspired mixture may be difficult with consequent inaccuracies in PaO(2)/FiO(2) assessment. In 30 severe COVID-19 patients, we observed that PaO(2)/FiO(2) values measured immediately before and after the transition from high-flow nasal cannula (HFNC) to one commercially available Venturi mask O(2) therapy were similar (bias mean value 0, standard deviation 23 mmHg). In COVID-19 patients recovering from respiratory failure, PaO(2)/FiO(2) is not different whether measured with a commercially available Venturi mask or HFNC.
