Lung Function test
Am a SPL holder, been at my training for a while now,
been having problems with my lung function test.
My 1st aviation took months just cos of the lung function test not coming well
I grew up with asthma, and I would say its controlled
I have since been grounded for months now,
cos after I went for my renew the same problems came up again
I want to ask for tips on how to manage this situation,
Besides the 1st aviation medical, it took like 8 blows that almost left me fainting
before I got the graph right,
Is there a technique to the blowing
Thanks
