High-flow oxygen therapy refers to a way of effective respiratory therapy for patients by providing high-flow, precise oxygen concentration, and warming and humidifying air-oxygen mixed gas. It can quickly improve the patient's oxygenation level and maintain the normal operation of airway mucus cilia.

High-flow nasal cannula oxygen therapy,HFNC is an oxygen therapy method that directly delivers a certain oxygen concentration of air-oxygen mixed with high-flow gas to the patient through a nasal catheter that does not need to be sealed.

Micomme's high flow nasal cannula (HFNC) OH series can quickly improve the patient's oxygenation level and maintain the normal operation of airway mucus and cilia. It is mainly suitable for mild to moderate respiratory distress Syndrome/hypoxemia and other patients with spontaneous breathing.
