You really need to alert the pulmonologist to your unusual sleep breathing pattern with inhale/exhale time of 3:1 and the really ragged inhalation. These are symptoms that do respond well to bilevel, and perhaps ASV. I never associated your respiratory issues with the cardio issues, but you show a lot of indications of upper airway resistance or flow limitation. Your doctor is best equipped to figure this out and get you on-track with the sleep therapy you need. Please consider taking in some printouts of the flow rate charts for him to see. Ideal would be to use EncoreBasic waveform printouts.cant do much of anything till the 4th of Jan when i see the new dr. I cant get in to my current one till Feb of next year. Im kinda stuck. I will take printouts then. I saw him years ago so im still in his system.
