Web15 de jun. de 2016 · High-flow nasal cannula (HFNC) oxygen therapy has several physiological advantages over traditional oxygen therapy devices, including decreased nasopharyngeal resistance, washing out of the nasopharyngeal dead space, generation of positive pressure in the pharynx, increasing alveolar recruitment in the lungs, ...
Web5 de nov. de 2024 · High-flow nasal cannula is thought to work through increasing the oxygen fraction in the alveoli by washout of the nasopharyngeal dead space, reducing the inspiratory resistance, improvement of airway conductance and by providing an end-distending pressure to the lungs (21–23). WebA major problem, however, is the lack of clinical guidelines. A better understanding of the washout effect (clearance of anatomical dead space) and the generated pressures …
