Oxygen therapy instrument refers to all kinds of oxygen deficiency treatment equipment, in addition to eliminate the causes of oxygen deficiency, can be given to oxygen therapy. Inhalation of high concentrations of oxygen to increase the amount of dissolved oxygen in the plasma can improve the supply of oxygen to the tissues. Hypoxia refers to the tissue oxygen supply is insufficient or the use of obstacles, caused by the body function metabolism and even morphological and structural changes in a series of pathological changes in the process.
Nasal plug and nasal catheter oxygen method, this oxygen method is simple equipment, easy to use. Nasal plug method has a single plug and double plug two kinds: single plug method to choose the appropriate type of plug in one side of the nasal vestibule, and close contact with the nasal cavity, inhalation only into the oxygen, so the oxygen concentration is more stable. Double plug method for the two smaller nose plugs at the same time placed in the bilateral nostrils, nose plugs around the gap remains, can breathe air at the same time, the patient is more comfortable, but the concentration of oxygen inhalation is not stable enough.

Circulatory hypoxia
1. Basic concept: the lack of oxygen supply to the cells is caused by the decrease in the amount of blood to the tissues and organs or the slowing down of the blood flow. is called circulatory hypoxia. It includes ischemic hypoxia and sludge hypoxia.
2. Causes: systemic circulatory disorders are seen in heart failure, shock, and so on. Local blood circulation disorder is seen in embolism, thrombosis, arterial stenosis, local bruising and other vascular lesions.
3. Mechanism of occurrence; in systemic blood circulation disorder, the volume of blood transfusion from the heart decreases, leading to systemic hypoxia, and in severe cases, the heart, brain, kidneys, and other important organs and tissues are deprived of oxygen, and the functional failure can lead to death of the animal. In local circulation disorders, the amount of blood flowing through the capillaries per unit of time decreases or slows down, and the amount of oxygen diffused into the tissue cells decreases.
