Hi. I understand your concerns. the test is not well performed. It could be due poor effort or uncalibrated machine. Lung age is calculated by machine itself. Ideally you should blow for min 6 secs. You have blown for only 3. 35 secs.
Hope your questions were answered. thanks.
There seems to be some problem in the pft software...Send me the full copy with the graphs and detailed history to comment on it..
