THAT is indeed the question. Why, with my peripheral O2 levels at 94/5 %even 96% am I still fighting to breath?
It goes like this. I wake short of breath. I rise and take my Oximeter (I have several; they all show the same) . My level is, say 92%. I do controlled breathing using a computer monitor and it rise to 94. I am still breathless. I need the loo so I get up and go. On my return the oximeter shows 82% - no surprise - all that muscle action!
Now be aware that I am on continuous oxygen by canular at 2.5 litres per minute.
I go back into controlled breathing, concentrate on nasal intake and the O2 sat rises to 92-3%. My breathing remains tight and difficult. I resort to the bluey. Little effect. I sit quietly for 10-15 minutes and everything returns to0normal. Hooray.
Until I decide to get dressed and we are off again. After 30 laborious minutes I am clad for the day. But still breathless, still on O2 of course and so await my sats to return top the mid 90s.
Now look - I know all about the lungs. How my little alveolis are so distorted they fail to pass O2 into the blood (even when I am stuffed with it canular inflation!). My blood capillaries are so damaged they do not pass blood well enough. And the bronchiectasis means I have stumpy little cilia (if any) to shift the naturally generated mucus up and out of the bronchi.
Which is why I am now on the nebuliser three times a day. Five minutes of 5mcg salbutamol. No diiscernible difference (and yes, I know I should not use the little bluey but what do you do in a hurry?).
Now a clue - I also have arrythmia and mild congestive heart disease (meaning oedema and continues furosemide). But I see no oedema in my limbs so it is not fluid.
CT and X-rays have shown nothing. Indeed, on some scales I am in decent nick for an 80s year old.
SO DOES ANYONE HAVE ANY IDEA WHY I MIGHT STILL BE SO BREATHLESS?
For info - I am 80, recovered from leukemia 20 years ago by allogenic bone marrow transplant, two bouts of HVGD pneumonia and diagnosed with emphysema and bronchiectasis by lung biopsy 2006, diagnosed with arrythmia 20016, mild congestive heart failure 2018.
