High Flow Nasal Cannula(HFNC) oxygen therapy is a form of non –invasive respiratory support, which comprises an air oxygen blender, an active humidifier, a single heated circuit and a nasal cannula. It delivers adequately heated and humidified medical gas up to 10-60L/min, and is considered to have a number of physiological effects: reduction of anatomical dead space, PEEP effect, constant fraction of inspired oxygen and good humidification.

It is widely used in RICU and ICU.
Precocious Chinese cabbage is not wrapped in the prevention and treatment methods
When cabbage is planted early, it tends to be long-leafed, uninvolved, and has a small cooking ball and low yield. The main reason is that the weather is high in temperature, rainfall is high, or high-temperature land loses water too quickly, and pests and diseases are seriously damaged, especially soft. Diseases such as rot, dry heart disease, downy mildew, powdery mildew, viral disease, aphid, cabbage caterpillar, etc.; improper fertilization, such as excessive nitrogen fertilizer, insufficient phosphorus and potassium fertilizers, uneven water supply, are also the main reasons causing Chinese cabbage not to contain . If you take the following technical measures to strengthen management, you can promote its inclusion. First, increase phosphorus and potassium fertilizers. After 25 to 30 days of Chinese cabbage planting, increase the application of P and K fertilizers, once every 10 to 15 days, apply 25 to 30 grams of potassium dihydrogen phosphate per plant (applying to clear water), or use retort to make mature manure and feces. Water diluted to 80 ~ 100 times after the application of liquid, even applied 2 to 3 times is appropriate. Second, spray foliar fertilizer. From the start of Chinese cabbage cabbage, sprayed with 0.3% potassium dihydrogen phosphate, 500 times Zhuangfengyou, and 1500 times Shennongsu chelate fertilizer mixture once every 7-10 days, spray 3 to 5 times. Evenly spray all the leaves to start dropping drops of water to improve the nutritional level of the leaves. Third, the cream moisturizing. During the growth of Chinese cabbage, it must be ensured that there is sufficient water supply. It should be avoided from time to time, when dry and wet, to prevent curling and wilting of the leaves of Chinese cabbage; when the weather is dry, fresh water is poured every morning and evening. In addition to spraying 1.5 to 2 kilograms, we must cover the surface with wheat straw or other weeds to reduce moisture loss and keep the soil moist. Fourth, control pests. Cabbage is harmed by diseases such as virus disease, soft rot, hanging wireworms, aphids, and so on. It will cause non-heart-wrapping and non-balling. Therefore, during Chinese cabbage cabbage, it is necessary to pay attention to inspection of the leaves and find that there are diseases and insect pests. , It is necessary to continuously spray 2 to 3 times 1500 times liquid agricultural music, 1500 times liquid SAM, or spray 1500 times liquid music, 1000 times liquid to kill the mixed liquid for prevention and treatment. If the soft rot disease is seriously damaged, 500 times of agricultural streptomycin should be added together with spraying.
