After effects of c-section while having bronchitis and asthma?

hi i am scheduled to have a c-section in two weeks and i just got out of the hospital with bronchitis and i have asthma pretty bad. my doctor said that she is worried that my lungs won't be healed in time but i don't know what i am suposed to do i can't control how fast they heal so has anyone had this problem? as far as problems after the surgery?
