Asthma Vs. Sleep Apnea

I was medically discharged from the USAF with asthma, during the testing in came to light that I was borderline sleep apnic. The VA rated me 10% for my ashtma and I am currently awaiting results of my sleep study. How are they gonna rate me if it comes back that I have OSA? Is the asthma going to affect how they deal with the sleep apnea?
