    Had lung function tests and now confused!

    Hey all

    Ive been having symptoms that my doc was pretty convinced was either COPD or Asthma.

    And today got my lung function tests.

    However my results convinced the Nurse not to bother with the second half of the test (opening airways) as she was convinced it was pointless.

    She said all my results where over 100% of expected normal readings (110-120%) and that it made opening my airways more pointless?

    So what does this mean? I dont have asthma? Or Could it mean my asthma is allergic?

    Thanks

    I am somewhat the same. Had lung tests today. Everything over 100%. Nonetheless, they administered the albuterol and did find a response in the "mid flow" reading. I am at the early stages of diagnosis, so don't understand everything yet. Did you do the diffusion of CO2 test? That test tells if anything is wrong with your alveoli, the tiny air sacks, and the spirometery won't tell you about that. The CO2 test would be better for COPD testing than asthma, I think.

    It could mean your symptoms are due to something other than asthma. Or it could be that your lung capacity is just bigger than average!

    How did you feel at the time the test was given? Have you tried an inhaler, and did it help? When do your breathing problems bother you the most?

    Well funnily enough when i went for x-rays they had to take two because (quote from radiologist) 'my lungs are bigger than she would expect' and she missed the bottom half on the first plate.

    I felt fine when the test was given. And she didnt feel it was worth doing the reliever test.

    My symptoms are always worst at night when i lie down... my other half has noticed that i am breathing through my mouth in my sleep instead of my nose, but the doctor doesnt seem interested in that...

    Beacon: No i didnt do a CO2 diffusion test...

    I did Vital Capacity (110%)
    FEV 1 second (115%)
    FEV/capacity? (110 I think?)
    And peak flow (673)

    the nurse said shes done countless spirometry tests and 'there is no way i have copd'

    Re: Had lung function tests and now confused!

    Well, no, with numbers that high, I really doubt you have COPD, and if you have asthma, it was probably not acting up at that time. See, asthma attacks may come and go, and someone with milder asthma who is feeling well at that moment can have a normal test. COPD, however, is progressive, and, though symptoms vary, some degree of lung impairment tends to be present all the time.

    The main thing they look at is the ratio. If your ratio is low, you might have asthma or COPD. But your ratio is quite high, and your total lung capacity is high.

    Now, it could be there's something other than asthma going on. With breathing problems that get worse when lying down, the most common causes I can think of are asthma, anxiety, and "silent" acid reflux disease. Could also be just congestion from allergies.

    So. If you have allergies, try antihistamines. Also try rinsing your sinuses with saline before bed. If you tend to eat dinner late, try eating earlier, and (if feasible) elevate the head of your bed or get a wedge pillow so you don't have to lie so flat.

    And keep pursuing answers!

    Re: Had lung function tests and now confused!

    Thanks jane that all makes a lot of sense, and yes theres variation, when i had an attack the first time (in bed i could barely breathe) my partner panicked and she insisted i go to the hospital. I refused but agreed to go to a walk in centre in the morning.

    I still felt rough when i got there- and my peak flow was only 560 at the time (still normal though). So it does seem very variable.

    Thanks for all the advice it is very much appreciated.

    Re: Had lung function tests and now confused!

    Sounds like mine - the doc was expecting to find me with asthma, but I came out with perfectly normal spirometry. I'm a singer/musician and I don't think they were taking account of the effects that has on lung capacity. If your personal 'normal' is 125% of average because you're an athlete, a musician, or somebody who has extra-large lungs you could lose a quarter of your breathing, and still come out 'fine' according to the tests, but you'd know that you weren't anywhere near where you were 'meant' to be.

    Hey Kaji,

    What further tests are they doing for you?

    After normal x-rays, blood test and spirometry i get the feeling my docs are washing their hands...

    Re: Had lung function tests and now confused!

    My doc said I didn't have asthma, and he thought I might possibly have a pulmonary embolism (but personally I found that highly unlikely)... he wanted me to have a CAT scan, and he also wanted to test to see what happened to my oxygen levels during activity. I didn't actually have either because I was feeling so much better. If they think you have asthma but you're not showing symptoms when they can see it, they can do a melancholine challenge and try to provoke it, but he didn't suggest that for me.

    Well its good news that your feeling better kaji

    I must admit i think my problem is my nose! My partner has commented that i am breathing out of my mouth lately...especially when asleep.

    Its having some unfortunate effects (my salivary ducts seem to be clogging up as a result of a very dry mouth)

    If your mouth is dry all the time and your eyes are dry too, look at Sjogren's disease. It's a rare one and unlikely but it can cause those symptoms.

    Re: Had lung function tests and now confused!

    There's more things than just asthma that can cause breathing difficulties, especially at night. Your problem COULD be from your nose - a deviated septum has a huge effect on your breathing patterns. Have you been tested for sleep apnea? How about acid reflux? It's a prime cause of nocturnal asthma because your stomach valve relaxes while you're asleep and you're lying down so the acid can back up in your throat and be inhaled (which causes asthma attacks). Even the healthiest set of lungs is going to have a fit if it gets droplets of stomach acid in it.

    Re: Had lung function tests and now confused!

    I would try to investigate those sinus issues. Saline nasal rinses can help a lot. If you might have allergies, then try antihistamines. I also personally recommend NasalChrom, it's a great spray for allergies. In the US it is available over the counter at a pretty low price.

    Might also be worth getting skin testing for allergies, if you are congested a lot.
