The treatment of type I and type II respiratory failure includes the treatment of the cause of the disease, only to improve and control the cause of respiratory failure, so that respiratory failure can be effectively relieved. patients with type I respiratory failure in the treatment of the cause of the disease at the same time should be given appropriate oxygen therapy, because at this time the patient is often accompanied by severe hypoxemia, can be given nasal catheter oxygen or mask oxygen, in order to improve the patient’s hypoxia as soon as possible, usually need a high concentration of oxygen, some patients can also be given ventilator-assisted respiratory therapy. High concentration of oxygen is needed, and some patients can also be given ventilator-assisted respiratory therapy. For type II respiratory failure to improve the patient’s ventilation, improve the effective ventilation of the alveoli, improve the patient’s carbon dioxide retention phenomenon, at this time, most need to be given to the antispasmodic, asthma, and some patients also need glucocorticoid therapy. The patient’s oxygen therapy needs low concentration oxygen, avoid high concentration oxygen, can also be given to the ventilator assisted respiration and other treatments.
