husband has sleep apnea and mild to mod copd--had been using cpap for years without any pulmonary problems. after another follow-up sleep study it was determined he also had central apnea. Last Dec was switched to bpap machine and since then he has had 2 severe episodes of wheezing. First time treated with z-pak advair and spiriva and problem resolved. This time didn't see MD soon enough-started on z-pak,sliding scale prednisone, advair and spiriva. Finished z-pak-was tapering down to 20mg prednisone,wheezing was somewhat better and spiked a fever and had to be admitted to hosp on IV Levaquin. Wondering if bpap could be causing these new lung problems.
