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...
High-flow nasal cannula (HFNC) oxygen therapy applied after extubation decreases respiratory rate (A), has no effect on tidal volume (B), it increases PaO2/FiO2ratio (C), and it did not modify arterial carbon dioxide levels (D), compared to standard oxygen. Horizontal red lines represent me...

The typical HAPE patient is in the emergency department for 1-3 hours depending on how bad they were and how they’re doing on the high flow oxygen. We wean them down, with a goal of getting them on a nasal cannula with 3-4 liters of O2, which is what the O2 concentrators and po...
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...
with a CPAP of ≤6 cm H2O and a fraction of inspired oxygen (FiO2) of ≤0.3 for at least 24 h, were randomly assigned to wean by using HHHFNC or wean directly from CPAP. In the HHHFNC group, flow rate was reduced by 1 liter/min every 24 h to 2-3 liters/min depending on ...

MATERIALS AND METHODS: We prospectively included ...
