Asthma testing

Doctor told me seasons are different for asthma testing inside glass box. Seems to me the box is a controlled environment, it would not matter what season it is. That is winter inside the box would not show asthma but somehow spring inside the box would show asthma. Any thoughts?

    Hmmm, that’s odd. Maybe the doc was trying to get at seasonal triggers? For example if the person had asthma exacerbated by tree pollen, testing in November might not show it but testing in May would?

    The tests inside the box mimic different asthma reactions by the products they give you I thought. How would seasons matter? If I am wrong I need someone to explain it to me.

    I found this about body plethysmography, and it sounded like just spirometry in an air tight box to allow determination of lung volumes and airway resistance. Not sure about what kind of products they’d give you. Maybe someone who’s gone through it could weigh in.

    That's an interesting article Em!  Thanks!

    I have had that test.  It was part of my Methacholine Challenge test.  If I remember correctly, after those measurements listed in Em's link above, I was given increasingly higher doses of methacholine, a drug that can cause an asthma attack in people with asthma.  If you do show signs of an asthma attack, they give you albuterol, in my case, to open your airways back up.

    I don't know what the other medicines might be used in the air-tight box.  

    Would be worth a call to your doctor.  I used to be hesitant to call my doctor with questions but finally realized that if I don't call, he will think I know what is going on when I don't.

    Hope this helps you!  Please let us know what your doctor says!

    Doctor who is sending me to the new doctor just told me to stop looking up things on the Internet. Was very upset I went to places like this one for help.

    Holy cow! I’d never go back to that first doctor again. It is your right as a patient to inform yourself by asking questions in the office and looking stuff up at home. Any caregiver who doesn’t understand that isn’t worth your time. You should tell him or her the age of paternalism is over! Frustrating. I’m sorry you were treated poorly.
