My husband has been experiencing episodes of sighing and breathing difficulty. A month ago, it seemed to come and go, but recently it's gotten worse. We finally saw a doctor who said he has bronchitis, even though his ECG, sugar, and most test results were normal, apart from a bit of chest congestion and a high TLC indicating some infection. He's on Augmentin, montair fx, and Pantop D now, plus an inhaler. Im concerned because hes still sighing and Im just wondering if this is normal as he starts treatment. His oxygen saturation is at 97-98. Should I be worried or is there anything else we should be doing to help him get better?
