FEV1 - what does it mean?

Hi, this is my first post here and not got a diagnosis yet but having tests done and hoping all is ok. Is it a good thing to have an FEV1 value above the normal range? It was 138 and I read that normal range is between 80% and 120%. In the process of trying to work out cause of breathing problems.

That's very good. Often athletes or singers can have a lung function well above the top range too.

FEV1

This value is expressed as a percentage, with normal test values being between 80% and 120% of the average (predicted) values.

You also need the FVC value similar to FEV

FVC

This value is expressed as a percentage, with normal test values being between 80% and 120% of the average (predicted) values.

If both values are within normal range the the test is deemed normal

Thank you for explaining. I think FVC was 117 so it sounds like everything is normal. I'm not an athelete or singer or even very active but it sounds like lungs are normal.

I hope you get the transplant if you need it and that it's a great success.

Thank you to everyone for your comments.

👋 Nanndake Thought might help my thinking knowledge is the FV forced volume when you exhale air & Fv breathing in is the the lung capacity off oxygen your lung fill. Usually god 109 percent . Below 50 run into diffucultys shortness off breath . Mine is 30 lung capacity lung function doesn't function on emptying bad air gaz exchange . Bernadette x x

Hi Nanaedake, my Fev1 is 132%, so similar to yours! My issues are caused by reduced gas transfer values. Did you get any results for those yet?

Look at the values for tlco and kco. There will be a number and a percentage given for each and probably a predicted value too, which is the reference value. Let me know if you need more help x
