27 yr old male,I am currently in the middle of being diagnosed with a rare neuromuscular disorders and had to undergo a lot of pulminary function testing. My family doctor did not understand the results so i have to wait 3 months until i see the neruomuscular specalisist again.
The breathing test that most stood out was called the FIF MAX(L/sec) and it showed a -30% drop when going from a standing to supine position. standing it was 6.29 and supine it was 4.38.
i was wondering significant that was, they were checking for diaphram weakness.
