I have low <span style = 'background-color: #dae8f4'>oxygen</span>
saturation (88-93). So far I have taken pulmonary function test, blood work, Chest CT scan, heart echo and another sleep test. i have heart disease, diabetes, and sleep apnea.
I am not sure what is happening. I am short of breath and sleeply all the time. Everybody seems like I should be on oxygen
but my doctor is first trying to find out why I have low oxygen
Any ideas what is going on?
