1, measurement range and accuracy of medical gas sensors should be matched with the secondary instrument, and should be higher than the control and accuracy process requirements. 2, the scope of work pressure or differential pressure sensor monitoring and sampling points should be more than 1.5 times the maximum possible pressure or differential pressure range should be 1.2 times that point - 1.3 times the normal range of variation. The scope of work should flow sensor is 1.2 times the system - 1.3 times the maximum working flow. 3, the sensor should be set independently powered emergency backup power. For disease respiratory disease and respiratory system disease is a common disease, primary lesions in the trachea, bronchus, lung and pleural lesions were more mild cough, chest pain, breathing oxygen affected the supply of high-quality equipment, heavy breathing difficult, 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 population and other factors, so that domestic and chronic obstructive pulmonary disease (COPD referred Hebei oxygen equipment manufacturers, including chronic bronchitis, emphysema, pulmonary heart disease ), bronchial asthma, the incidence of lung cancer among diffuse pulmonary fibrosis SPA molecular sieve oxygen concentrator, 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. Not the normal effects of oxygen intake of these diseases is very large, and even death, so patients these diseases requires an oxygen machine oxygen.
