What might cause low oxygen saturation with normal lung tests while taking Jakafi?

Low oxygen levels despite normal lung function tests and imaging could be related to anemia (low red blood cells), which is a known side effect of Jakafi. When red blood cell counts are low, your blood can't carry oxygen as efficiently, even if your lungs are working normally.

Jakafi can cause several blood-related issues that might contribute to this:

* Anemia (low red blood cell count)
* Low white blood cell count
* Bleeding problems

Low lymphocytes (a type of white blood cell) combined with immunosuppressive medications can also increase infection risk. Even though imaging might look clear initially, infections could affect oxygen levels before showing up on scans.

It's important to discuss these symptoms with your healthcare team right away. They may need to:

* Check your complete blood counts more frequently
* Rule out infections that might not show up on imaging yet
* Evaluate whether medication adjustments are needed
* Consider other causes of low oxygen that aren't related to lung structure

The combination of low oxygen with normal lung tests suggests the issue may be related to blood oxygen-carrying capacity or early infection rather than lung damage from GVHD itself.
