Can anyone tell me what these results mean? My pulmonologist has not called to discuss results with me yet. I am thinking about discussing the zephyr valve with him. I am short of breath most of the time, having to use nebulizer 5 or 6 times a day, I wake up several times at night needing a breathing treatment. It just started getting this bad November 2024 when I had a cold. Before then I only had to use nebulizer when I was sick. I have used many maintenance inhalers with no improvement. Thank yo
