Great work Dr Waleed. As we known, the cut-off point between restrictive and restrictive pattern on PFTs is FEV1/FVC is 70% of predicted. Is there is any change in this area?
Please do not mix between FEV1 % and FEV1/FVC ratio Gold 1-4 is according to FEV1 % from the predicted But when you talk about FEV1/FVC to say Low " Obstructive" or "Normal-to high" with ? restrictive the cut off is 0.7 No change in the guidelines from GOLD Did i say anything different in my Video !! if yes, could be a mistake...
Very useful diagram to read flow volume loop and know different patterns www.google.com.sa/url?sa=i&rct=j&q=&esrc=s&source=images&cd=&cad=rja&uact=8&ved=0ahUKEwi8xOKYkL7TAhVIDcAKHRN0CEYQjRwIBw&url=https%3A%2F%2Fwww.pinterest.com%2Fpin%2F313211349061196918%2F&psig=AFQjCNFL-3tfVncVKZS2qHLzf9sR2zWv9Q&ust=1493158806986868 Another way of looking at PFT www.lungfunction.com.au/assets/images/flow-volume-loops.jpg
thanks alot our dear senior
You are most welcome
Wonderful lecture ,we need more and more
Thank you very much
would love to see more examples of different long cases

There is no discrepancy 70% or 0.7
No they are the same
What i mean did i say anything else in video!!

I guess you did not mention FEV1/FVC
