It is not possible to generalize how long you can live with type 2 respiratory failure upper respiratory function, the exact survival time is related to the original disease, the presence of complications, the treatment method and effect, the physical condition and other factors. However, the earlier the disease is detected, diagnosed and treated, the less impact it has on life expectancy. It is recommended that patients undergo regular treatment as early as possible. Type 2 respiratory failure is defined as a condition in which the partial pressure of oxygen in blood gas analysis is less than 60mmHg and the partial pressure of carbon dioxide is more than 50mmHg. Patients with type 2 respiratory failure can have their ventilation improved by ventilator-assisted ventilation. Common diseases that cause type 2 respiratory failure include: lung infection, acute exacerbation of chronic obstructive pulmonary disease, pulmonary heart disease, acute heart failure, acute myocardial infarction, and acute pulmonary embolism. Improvement of respiratory failure in addition to symptomatic improvement of ventilation also need to correct the primary disease and other symptomatic treatment, such as pulmonary infection, can be given to anti-infective treatment, such as acute exacerbation of chronic obstructive pulmonary disease, need to clarify the cause of exacerbation, remove the cause at the same time given to antispasmodic asthma, such as cardiac failure, cardiac, diuretic to improve symptoms. Type II respiratory failure patients, such as reversible causes, can be assisted by respiratory ventilation and other symptomatic treatment at the same time to correct the cause of the disease, so as to improve the prognosis of the disease, to reduce the adverse effects of the disease, the patient is still hopeful of a normal life, it is recommended that the patient is actively engaged in formal treatment.
