I had a “substantial” ie I met the threshold of 10% improvement with Albuterol on PFT, but just barely. When I asked my doctor for a prescription for 7 % saline, he included albuterol without any explanation as to why. When I asked if I could do saline only, he said “sure” again without explaining what the benefit of the albuterol, if any might be. So, I only did the saline when I started AC, but then my pulmonary rehab therapists thought albuterol is important to open airways so suggested I include before AC. For the last couple weeks I have done albuterol before saline and I notice no difference than nebulizing saline only. I have no shortness of breath or chest tightness. Perhaps I should just stick with the saline, as was my initial inclination.
