High-flow nasal cannula (HFNC) is a relatively new device for respiratory support. In pediatrics, HFNC use continues to increase as the system is easily set up and is well tolerated by patients. The use of nasal cannula adapted to the infant's nares size to deliver heated and humidified gas at high flow rates has been associated with improvements in washout of nasopharyngeal dead space, lung mu...

Background: Heated humidified high-flow nasal cannula (HHHFNC) is gaining popularity as an alternative to nasal continuous positive airway pressure (nCPAP) therapy in the management of preterm neonates with respiratory distress due to ease of administration and patient comfort. However, limited evidence is available addressing its risks and benefits. To study the efficacy and safety of HHHFNC i...

Background: Heated humidified high-flow nasal cannula (HHHFNC) is gaining popularity in the management of respiratory distress in preterm neonates. However, it is not known whether it takes precedence over the gold standard nasal continuous positive airway pressure (NCPAP) in this age group as a primary mode of non-invasive ventilation (NIV). There is limited evidence ...

Recently there has been growing interest in an alternative to conventional oxygen therapy: the heated, humidified high flow nasal cannula oxygen therapy (HFNC). A number of physiological effects have been described with HFNC: pharyngeal dead space washout, reduction of nasopharyngeal resistance, a positive expiratory pressure effect, an alveolar recruitment, greater humidification, more comfort...

OBJECTIVE Actively heated, humidified high flow nasal cannula oxygen therapy (HFNC) is a new type of oxygen therapy. Because of its unique physiological effects, the clinical application is becoming more and more popular. This article is to summarize the physiological effects, clinical application and short comings of HFNC. Compared with conventional oxygen therapy, HFNC helps to improve oxygen...

Humification of oxygen prior to administration by nasal cannula is an expensive practice which has been justified on the basis that it improves the comfort of patients receiving supplemental oxygen therapy. Routine humidification of low-flow oxygen (less than or equal to 4 L/min) delivered by nasal cannula has recently been challenged based on theoretic grounds and on the results of a clinical ...
