For disease respiratory disease respiratory disease is a common disease efficient oxygen, the main lesions in the trachea, bronchus, lung and pleural oxygen machine design and installation, the lesions were mostly mild cough, chest pain, breathing affected , severe dyspnea, hypoxia, respiratory failure and even 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 of diffuse pulmonary fibrosis between the principle of oxygen, as well as 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 oxygen, so patients need one of these diseases oxygen oxygen machine. 1, medical gas dew point sensor accuracy drift should be less than 1 ℃ / year. When the concentration of carbon monoxide sensors 10 × 10 -6 th, the error should not exceed 2 × 10 -6 th power of 2, air alarm pressure sensor should be installed in a pipeline main valve side. 3, the area should be set to repair the valve alarm sensors, alarm sensor area should not use electrical contacts. In addition to the operating room, anesthesia outdoor area should set alarm sensors on the pipeline valve area using side.
