Lung Disease: Thoughts? How about we are very scared for you. You have a significant respiratory infection or an illness that will end your life early. Please get to the doctor and get this figured out. Lung specialists are known as pulmonologists.

Sleep apnea: You likely has sleep apnea causing oxygen to decline with sleep. You need a sleep study if overnite oximetry shows desaturation as you state.

Why does oxygen saturation go down when using a bpap?

It shouldn't: The purpose of a positive pressure machine (cpap, bipap, apap) is to increase the gaseous exchange in the lungs and raise saturation. The machine may not be adjusted properly. Consult the respiratory technician for help/advice.

Depends: Low oxygen levels can affect someone's judgment and arousal. But, this is variable between people. I have met plenty of people with very low oxygen levels and can act and feel fine. So, there is no general rule about that...
A 33-year-old male asked:

Is 98 percent oxygen saturation level for a smoker who has been smoking for19 years good?

Smoking and Oxygen: Yes. But the test is deceptive. It does not mean you do not have lung damage. It does not measure how much carbon dioxide you have or how many of your red blood cells are no longer available to carry oxygen. It just tells me that you are still young enough that you have some ability to maintain good oxygen levels despite the nineteen years of trying to damage your lungs.

Several factors: Several factors determine oxygen saturation. These include the amount of oxygen you breathe, the ability of the lungs to extract oxygen, the amount of red cells to carry oxygen, the ability of the heart and blood vessels to deliver oxygen to tissues, and efficiency of organ to use oxygen, any problems affecting these can cause low saruration. Treating a disease, exercise, supplemental o2 may help.
