Nasal plug and nasal catheter oxygen inhalation method, which is simple in equipment and convenient to use. There are two methods of nasal congestion: one is to choose a suitable model and put it in a nasal vestibule, which is in close contact with the nasal cavity. Only oxygen is introduced when inhaling, so the oxygen concentration is relatively stable. Double plug method is to put two smaller nasal plugs into two nostrils at the same time, and there is still a gap around the nasal plugs, so you can breathe air at the same time. The patient is comfortable, but the oxygen concentration is not stable enough.

Circulating hypoxia
1. Basic concept: insufficient oxygen supply to cells caused by decreased blood volume or slow flow rate in tissues and organs is called periodic hypoxia. Include ischemic hypoxia and congestive hypoxia.
2. Reason: Systemic blood circulation disorder is seen in heart failure and shock. Local blood circulation disorders can be seen in vascular diseases, such as embolism, thrombosis, arterial stenosis and local congestion.
3. Occurrence mechanism; When there is systemic blood circulation disorder, the output of the heart decreases, resulting in systemic hypoxia. In severe cases, the heart, brain, kidney and other important organs and tissues are deprived of oxygen, and the failure of function will lead to the death of animals. When local blood circulation disorder occurs, the blood flow through capillaries decreases or slows down per unit time, and the oxygen diffused into tissues and cells decreases.
