For disease respiratory disease respiratory disease is a common disease, the main lesions in the trachea, bronchus, lung and pleural lesions were mostly mild cough, chest pain, breathing affected, severe dyspnea, hypoxia, and even respiratory failure and death. The mortality rate in the city accounted for the first three, while in rural areas accounted for first place. More attention should be paid is due to air pollution, smoking, aging and other factors, so that domestic and chronic obstructive pulmonary disease (COPD for short, including chronic bronchitis, emphysema, pulmonary heart disease), bronchial asthma, lung cancer, The incidence among diffuse lung fibrosis, and lung infections and other diseases, the mortality rate increased. These diseases include pneumonia, bronchitis, chronic bronchitis, viral respiratory infections, asthma, emphysema, pulmonary heart disease. Can not affect the normal intake of oxygen for these diseases is very large, and even death, so patients need one of these diseases oxygen oxygen machine. Oxygen is very important to the human body, healthy people under normal conditions, natural oxygen breathing air, and take advantage of the oxygen oxygen machine Which is better, to maintain metabolic needs. In the event of sickness or some abnormal condition, it is necessary at home or in clinics, hospitals, inhaled oxygen through a certain device. Oxygen common methods are: (1) a stuffy nose and nasal oxygen catheter method: This method of oxygen equipment is simple, easy to use. Stuffy law with a single plug and two double plug: Single-safa selection of appropriate models plug in the side of the nasal vestibule, and in close contact with (the other side of the nostrils open) and nasal inspiratory oxygen-only, so the oxygen concentration more stable. Double safa two other smaller stuffy nostrils placed simultaneously, stuffy surroundings still leave gaps, to breathe the air at the same time, the patient more comfortable, but the oxygen concentration is not stable enough. Nasal catheter is a catheter (commonly catheter) is inserted through the nose to the top of the soft palate rear nasal oxygen machine model, the oxygen concentration constant oxygen species, but a long time there will be discomfort and easily clogged secretions . Nasal congestion, nasal oxygen catheter method is generally only suitable for low-flow oxygen, if it will not tolerate relatively large flow velocity and impact force due to great people, but easily lead to airway mucous membranes dry.
