What is the highest a PFT can be, my bf has been in the 110's in the past and was 91 a year ago, but was down to 73, and had to do a tune up, a few days in he was at 93. I don't know what the range is on these numbers, and how high they need to be,  or how high the Doctor's are trying to get him.... any ifo would be really helpful

There is no 'highest', sorry.

What the FEV1 % stands for is the percentage of your usable lung volume compared to a 'normal' person.

As an example (not real #'s): If a normal 20yr old male can expel 2L of air; and one with CF does 1.5L then his FEV is 75%. If the one with CF happens to put out 2.1L then it is 105%.

As for a target, most CFer's I'm aware of focus more on not losing ground vs a certain #. IE if you are at 90 before getting sick, you want to get back to there if at all possible as quickly as possible.

To add a bit more to that, the percentage is further based on others of the same size in addition to age and sex (A 20yr old male that is 6' tall will have a larger typical lung volume than one that is 5' 6" tall. Men also have different expected values than women do.)<br>
<br>I agree that while overall percentage is an important thing to know, trends over time are the most important when looking at them in the context of a progressive disease- since we are always looking for ways to slow said progression as much as possible.
<br>
<br>Even someone who still has 'great' numbers, for example, has reason for concern if a significant amount of ground is lost w/o understanding why; and if numbers go up you sure want to know why so you can keep it up... both again as reflections of your own personal trend reflecting individual disease course.

<P> i blew 2.89     so its 90%</P>
<P> </P>
<P>I asked the Rt who was testing me once how much his fev 1 was  he said 143 %...big healthy guy lol</P>
<P>and he said his was the highest of the RTs...be very interesting to know for example what an athletes fev 1 would be</P>
<P> </P>
<P>one time I kept blowing 150%  and RT  is  looking for hole in hose and such ... I look at computer screen and here RT put wrong person in, he picked a 5ft 105 lb woman....</P>

Okay, you guys all put this stuff into a little more perspective for me... I totally dont understand alot of stuff about CF. My bf was diagnosed at about 3 months. But he doesn't know alot about the disease, I don't think he wanted to know all the technical stuff....So while he's been in for a tune up and I've been scared to death, Ive been researching to calm my fears.. And like I've told him I'll be his little encyclopedia on CF... if he wants to know something I'll figure it out. He was never very talkative about it, and I haven't been able to go to a dr's appointment with him, due to my own schedule. But he is very healthy, they just want to keep him that way... and he needs to be more consitent w doing therapy and eating... So I think I've learned alot this week in the hours I've been scouring this site.
