WebHFNC could be considered as ventilatory support in COPD patients, as physiological studies suggest its favorable effects on the work of breathing and gas exchange. 72–74 HFNC delivers a humidified and heated gas through a nasal cannula at high flow rate, reducing anatomical dead space in the upper airways by clearing exhaled carbon dioxide. 28,29 … WebThrough a nasal cannula a high-flow system delivers flows that approach (and can meet) total respiratory demand. This flow, being delivered though a small diameter delivery system and small-bore nasal cannula allows the flow that would traditionally move slowly through the upper airway to move quickly and maintain a constant stream of fresh gas which …
