Before oxygen therapy is prescribed there are guidelines or criteria that must be met. These criteria involve a blood test. (These blood test criteria must also be met for Medicare and other insurers to pay for the oxygen costs.) Medical experts produced the criteria. They establish what the levels of oxygen in the blood must be for oxygen therapy to be needed.
Tell your doctor about any changes in your symptoms and whether you have had any flare-ups. Your doctor may change your medicines based on your symptoms.
The sooner COPD is diagnosed, the sooner you can take steps to slow down the disease and keep your quality of life for as long as possible. Screening tests help your doctor diagnose COPD early, before you have any symptoms.
Talk to your doctor about COPD screening if you:
Are a smoker or an ex-smoker.
Have had serious asthma symptoms for a long time, and they have not improved with treatment.
Have a job where you are exposed to a lot of chemicals or dust.
The U.S. Preventive Services Task Force (USPSTF) doesn't recommend COPD screening for adults who are not at high risk for COPD.5 And some experts recommend that screening be done only for people who have symptoms of a lung problem.6
