Clinical application of High-flow nasal cannula oxygen therapy in acute heart failure
Abstract The High-flow nasal cannula (HFNC) oxygen therapy has received attention as an alternative to respiratory support in critically ill patients. It gives you a continuous flow of fresh gas at high flow rates replacing or washing out the patient’s pharyngeal dead-space. Every breath that the patient now breathes will be cleared of carbon dioxide and replaced with an oxygen-rich gas, which improves breathing efficiency. Although the use of HFNC in adults who are critically ill has been dramatically increasing, the advantages and disadvantages of each element have not been well discussed. Although the use of HFNC in critically ill adults has increased dramatically, its advantages and disadvantages have not been well discussed. The pathophysiological mechanism of AHF caused by dyspnea and hypoxia is different from the primary respiratory disease, the indications, timing and efficacy of HFNC in AHF treatment are not satisfactory. This paper reviews related research in recent years to improve the AHF respiratory support level with reasonable use of HFNC.
