How to turn pft read-outs into percentages

Just as the title suggests.

I have a log of pft's (fev1, fvc, fev1/fvc, fef 25-75%, pef).

Sometimes I get a summary report with it, which tells me my fev1(L)% of predicted, fvc(L)% of predicted and fev1/fvc%. Sometimes I don't get this summary.

Does anyone know how to change the read-outs into the predicted percentages?

Thanks

Basic math would say in order to get a percentage, you multiply by 100/1. So if you scored 5/10, that goes to 500/10 which equals 50%.

Put your score over your predicted score (so maybe 2.32L/3.50L: multiply to get 232/3.50 and you get 66.28%). I hope that makes some sense!! <img src="i/expressions/face-icon-small-smile.gif" border="0">

Ok, that makes sence. But, <u>I don't know what my predicted would be</u>.
Predicted = compare my results to someone of same height, weight & age w/o CF.
I guess the next question is: where do I find what my predicted would be. Is there a chart somewhere?

All those predicted numbers are based on YOUR previous results and are determined by a formula from the American Thoracic Society. As far as I know, there's no chart that you can use. It's usually the actual volume (in Liters) of your FEV1 that the doctor looks at and not the percentage anyway. I wouldn't bother obsessing about the percentages. It's energy you could spend elsewhere.
