Fig. 1. The high flow nasal cannula (HFNC) system incorporated an air/O2 blender with a flow meter and a heated humidifier. For the HFNC protocols, nasal prongs were connected to the manufacturer's standard circuit. We made 2 holes in a polyvinyl chloride cylinder to simulate adult external...
accurate temperature control is important to ensure that the temperature of the inhaled gas at the nasal cannula. Typically, the temperature of the inhaled gas to a patient is set at 37 degrees or slightly lower, supported by prior clinical studies. An advantage of the heating/humidification unit...

Difference in PaO2/FiO2 between high-flow nasal cannula and Venturi mask in hypoxemic COVID-19 patientsThe 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...
