For those of you that use an ASV with a flow limitation algorithm: I am curious to know how much your pressure changes in different sleep stages and does this pressure also increase as the night progresses?
Regarding breathing, is expiration easier with nasal pillows compared to a full face mask? And is it easier to trigger ipap (initiate inspiration)?
Is a low tidal volume, while on bipap with a high pressure support, generally more characteristic of lung issues?
Tv ranges mostly between 275-325 thoughout the night, though I’m a 70kg/155lbs male.
As a young aged child (<10 years old), I only experienced asthma attacks on ocassion. After a few years of using inhaled steroids, it got fully under control and never got attacks anymore. Therefore my doc decided I could stop taking it. Years later (late teens), it crept back in very slowly. So symptoms include: a constant shortness of breath, a feeling of the airway swelling in heat, chest tightness, and wheezing when exhaling very hard OR very softly, but never an asthma attack. My stamina is also really poor. Very occasionally, I also experience the classic asthma symptoms, like a subtle wheeze when breathing out normally and then I take my "rescue inhaler" and that helps, but not for the other symptoms. Since this crept in slowly over a period of about 4 years, I never realized it was my asthma. I have now been on inhaled steroids (Fostair Nexthalor 4 puffs/day) for just 16 days: I do notice some difference, though not that much yet. I do notice a better sense of smell in my nose though.
Given my case, is there a high chance that because it was left untreated for so long, it will take much longer for these symptoms to subside?
^ And did anyone experience this as well?
