Description

technical field [0001] The invention relates to the technical field of oxygen therapy, in particular to a non-invasive ventilation device, a control method and a control system for nasal high-flow humidified oxygen therapy. Background technique [0002] Transnasal high-flow humidified oxygen therapy (HFNC) is a new type of oxygen therapy. The nasal high-flow humidified oxygen therapy instrument mainly includes a flow generating device, an air-oxygen mixing device, a heating and humidifying device, and a nasal oxygen tube oxygen delivery circuit. . The HFNC instrument can provide gas with 21%~100% oxygen concentration, 31℃~37℃ temperature, and 2L / min~80L / min flow rate, which is used to treat mild to moderate type I respiratory failure, mild respiratory distress, and mild ventilation function. Obstacles, intolerance or contraindications to traditional oxygen therapy or non-invasive positive pressure ventilation. [0003] The non-invasive ventilation in the nasal high-flow hu...
