WebIn cardiac surgery patients with pre-extubation PaO2/inspired oxygen fraction (FiO2) < 200 mmHg, the possible benefits and optimal level of high-flow nasal cannula (HFNC) support are still unclear; therefore, we compared HFNC support with an initial gas flow of 60 or 40 L/min and conventional oxygen therapy. Web1. The Venturi mask uses the Bernoulli principle, described in 1778, in delivering a predetermined and fixed concentration of oxygen to the patient. The size of the constriction determines the final concentration of oxygen for a given gas flow. This is achieved in spite of the patient's respiratory pattern by providing a higher gas flow than the peak …
