Web24 de nov. de 2016 · One of the techniques of administration of oxygen in bronchiolitis is represented by the high flow (HFNC) or by a system in which oxygen is delivered to 2L/kg through nasal cannulas. The HFNC provides humidification, heating and oxygen, ensuring a minimum positive pressure, reduces breathing load and allows for better nutrition. Web17 de dez. de 2024 · Notably, the key finding showed patients with severe COVID-19 were significantly less likely to need mechanical ventilation when given high-flow therapy in comparison to conventional low-flow oxygen therapy. Other secondary outcomes that were measured in this study include risk of intubation and median ventilator-free days.
