Chronic Obstructive Pulmonary Oxygen Saturation of 90% or more do you still need oxygen?

Chronic Obstructive Pulmonary Disease (COPD) usually does not require oxygen if the long-term oxygen saturation is above 90%, but for patients with moderate to severe hypoxia, oxygen is recommended to correct and improve the situation.
Oxygen intake is also called oxygen therapy, and long-term home oxygen therapy is one of the treatments for COPD. Patients achieve improved ventilation of the lungs through continuous low concentration oxygen flow inhalation, thus helping to correct the hypoxic state of COPD. If oxygen saturation is maintained above 90% for a long period of time, it indicates that the disease is relatively stable and oxygen is usually not needed.
For patients with moderate-to-severe hypoxia, long-term oxygen saturation is lower than normal, and oxygen saturation can reach more than 90% after oxygen intake, in this case it is recommended to take long-term home oxygen therapy, oxygen intake time >15 hours or more per day, which can improve the quality of life.
Chronic obstructive pulmonary patients with acute dyspnea, wheezing, double lower extremity edema and other symptoms, should be alert to disease exacerbation, it is recommended to seek early medical treatment.
