Need some medical advice on this. I can't seem to find any answers on the internet one way or another.
I've had to do this test about 3 times now, and I'm curious about how safe it is. Honestly, I dont feel it is safe at all.
For those who dont know what it is, the nurse has a plastic tube about an inch in diameter connected to a measuring machine. The procedure is to take a deep breath then put your mouth on the tube, you then forcefully exhale all of your breath, and then you have to keep pushing out every last bit of air you can, and you have to keep doing this for about 5 to 8 seconds.
5 to 8 seconds of having to try and keep pushing air out when you have exhausted all your air in the first forceful breath.
Needless to say, you are straining, your eyes start watering, all the blood and pressure goes to your head and your eyes feel like they are about to pop out.
During this process, because you are straining so hard, your head starts to hurt very badly and you get a little light headed as well. The nurse told me they have people do this sitting down just in case people pass out.
This has to be repeated 3 times, or as many as it takes to get the result they are looking for.
Here is my issue, how can the AMA, or any of the other medical boards consider this safe? With that much strain and pressure you are exerting, one would think there is a concern for popping blood vessels or aneurism in the brain.
Does anyone with medical knowledge have any input on this. It seems to me to be a very dangerous test, and there has to be another way of determining lung capacity.
Just curious I guess
