How long can one live with moderate obstructive pulmonary ventilation disorder is mainly related to the severity of the disease, treatment, and individual factors of the patient, and should be analyzed with specific questions and not generalized. Pulmonary ventilation disorder is a decrease in respiratory function due to complete or incomplete blockage of the airways. If the result of pulmonary function test FEV1/FVC <70%, it is defined as obstructive, and FEV1 in the range of 60-70% is considered as moderately obstructive, and it is recommended that the patient undergoes a pulmonary function diastolic test to clarify the diagnosis. If the patient is in good health, lung function can be completely normalized after treatment of some diseases, such as asthma, and usually has the same life expectancy as a normal person. Patients can usually survive for a long time without affecting their life expectancy. However, some patients can progress to severe obstructive ventilation dysfunction with the progression of the disease and develop complications such as pulmonary heart disease and chronic respiratory failure, which are poorly treated, but the specific survival time varies widely among individuals, and it is not possible to give a clear clinical answer. Therefore, it is recommended that patients with moderate obstructive pulmonary dysfunction should quit swallowing at an early stage, actively engage in respiratory exercise, and regularly use bronchodilators to improve their prognosis.
