High-flow respiratory humidifier is a new oxygen therapy, which has been proved by a large number of clinical studies at home and abroad.The device is composed of an air-oxygen blender, a humidifier, a single heating circuit, a large-diameter nasal congestion catheter or a tracheostomy connector, and a mask adapter.

For a long time, people have believed that oxygen inhalation therapy is an effective method for critically ill patients, especially for patients with severe COPD and acute episodes of hypoxia, which can effectively relieve the patient’s life-threatening effect. Once the condition improves, people take it for granted that there is no need to inhale oxygen, and even worry about whether long-term oxygen inhalation will become addictive and harmful to the body.
