How long a person can live with loss of lung function varies from person to person, depending on the severity of the condition.
Patients with loss of lung function cannot rely on their own respiratory movements to provide oxygen to the body, nor can they eliminate carbon dioxide from the body, which may lead to toxicity, so they need to use a ventilator to help the patient to exchange gases, in order to maintain life.
If the respiratory function is normalized during the treatment, the survival time will be a little longer. If the respiratory function cannot be normalized, the patient can only rely on the ventilator to maintain life. Once off the ventilator, life may be lost at any time.
Patients with loss of lung function should go to the hospital in time to find out the cause of the disease and take targeted treatment.
