| The common diseases of respiratory system mainly include child bronchitis, chincough, bronchial asthma, bronchiectasis, pulmonary infarctron, emphysema, pulmonary heart disease, etc. These patients breathe terribly hurried and should be treated with oxygen therapy first aid immediately to alleviate sufferings of patients. Furthermore, uremia, diabetic coma, hepatic coma and barbital toxicosis don't belong to diseases of respir atory system but these diseases will make patients breathe slowly so that all need oxygen therapy first aid immediately.
When patients absorb air which owns higher oxygen concentration (28 ～ 31%), the oxygen will enter into pulmonary alveolus at once and arrive capillary vessel through capillary vascular membrane of pulmonary alveolus. With that, it will combine with haemoglobin inside erythrocyte and saturate directly, making blood oxygen content ascend rapidly. In this way, carbon dioxide can be efficiently prevented to congregate in body, air inside pulmonary alveolus can got renewed constantly and oxygen content inside organise got increased, so that oxygen demand of patients can be maintained when diseases coming on. |
