Forced vital capacity (FVC) as an indicator of survival and disease progression in an ALS clinic population as originally seen in The Journal of Neurology, Neurosurgery and Psychiatry
Last week were talking about outcome measures in ALS. In looking at those, we found forced vital capacity (FVC) was an important one to keep track of, and saw a demo of how this test is performed. The above article tells us how to interpret those results.
The cut-off score is 75%. Over 75% you’re likely to have more time until you’re dependent on a tracheostomy, on average about 4 years vs. 3 years for those who start out at less than 75%. The FVC test is important to conduct and follow-up test, because it’s respiratory distress (can’t breath well) that usually ends up causing death in those with ALS.
So that was short and sweet.
Since it was, I wanted to take a moment to ask your help on my little survey here. Just want to know who’s floating around the website and how I can improve the experience here. That’s all. 10 questions in 1-2 minutes. Thanks!
