High-flow nasal cannula (HFNC) is extensively used for acute respiratory failure. However,
questions remain regarding its physiological effects. We explored 1) whether HFNC …

Rationale: High-flow nasal cannula (HFNC) improves the clinical outcomes of nonintubated
patients with acute hypoxemic respiratory failure (AHRF). Objectives: To assess the effects of …

INTRODUCTION: High-flow nasal cannula (HFNC) can deliver heated and humidified gas
(up to 100% oxygen) at a maximum flow of 60 L/min via nasal prongs or cannula. The aim of …

Purpose Limited data exist on the correlation between higher flow rates of high-flow nasal
cannula (HFNC) and its physiologic effects in patients with acute hypoxemic respiratory …

The high-flow nasal cannula (HFNC) has been recently used in several clinical settings for
oxygenation in adults. In particular, the advantages of HFNC compared with low-flow oxygen …

Background: Delivery of warm, humidified, supplemental oxygen via high-flow nasal
cannula has several potential benefits; however, the high-flow range may not maintain …

Introduction Several reports have described the usefulness of a high-flow nasal cannula
(HFNC). However, the physiological mechanisms of this system are unclear. In the current …

Background Although clinical studies of the high-flow nasal cannula (HFNC) and its effect on
positive end-expiratory pressure (PEEP) have been done, the washout effect has not been …

BACKGROUND: High-flow nasal cannula (HFNC) is supposed to provide additional PEEP
compared with conventional oxygen therapy. However, the exact determinants of this PEEP …

BACKGROUND: High-flow nasal cannula (HFNC) enables delivery of humidified gas at high
flow while controlling the FIO2. Although its use is growing in patients with acute respiratory …
