can asthma be just smaller airways in general?

i'm beginning to wonder if my lungs might just be on the smaller side, in addition to the fact i'm a real sensitive person! My peak flows never come up above 400, even on an amazing day. Once, I hit 470, but that was while on a whole handful of medicines. The thing is I feel fine most days, even though my peak flows are usually between 300-350(under 250 is red zone for me I believe), which is yellow zone. Is it possible my lungs are just smaller & my airways a little smaller than the average person, i'm on the smaller/shorter/thinner side & am underweight. Has anyone ever found out that was part of the problem? Just wondering.. b/c I don't start to feel miserable until I get lower than 300 usually & wondering why that is.. some people get so sick if they slip even a little past the green zone but i'm fine until I get closer to my red zone. What's up with that??

Re: can asthma be just smaller airways in general?

Lung volume has little or nothing to do with weight, except to the side of the morbidly obese, where the superlatively overweight will have problems with decreased volumes.

Lung flows, such as your peak flow values, are a measurement of the caliber of your airways, that is correct. And although it is possible for you to anatomically have narrower airways, it's highly unlikely, since you have a personal best of 470. If you've done it in the past, your airways are capable of being that open.

Two possibilities exist; possibly more. 1) That you aren't properly controlled with your asthma, which would almost certainly take a full pulmonary function test for your doctor to say for sure, and 2) that your peak flow technique is simply inconsistent or incorrect altogether.

I think that maybe if you were a premature baby, it could be possible, but like wrin said - if you've done 470 in the past, you CAN get that open.

And to wrin - are you a respiratory therapist? It just seems to me that you've got the same ideas as RTs I've met in the past. Heh, and if you're not, just ignore me.

Re: can asthma be just smaller airways in general?

Whether I was or wasn't, saying I was would lend my person on this board a weight that cannot be proven with credentials, and thusly really can't be talked about on this board.

Healthboards has somewhat of a zero-tolerance policy with things such as this, whereupon nobody is really allowed to run around touting credentials that cannot be physically produced or making professional opinions without the opportunity to assess someone.

I guess what I'm saying is I can't say what you want me to say so I think I'm saying what you think I'm saying if you know what I'm saying.

Or maybe not.

Re: can asthma be just smaller airways in general?

From personal experience I can tell you that there have been time when my smaller airways are much more constricted than my larher airways. Once I had an FEV1 of around 67% and an MMEF of 24% another time an FEV1 around 75-80% and MMEF around 58%.

Maybe you have more probs with your smaller airways tha larger airways?

Re: can asthma be just smaller airways in general?

how would I know if it was my smaller airways, PFT's? I don't like my pulmonary doctor, maybe if I get a new one i'll go back lol. I don't think I had complete PFT's the last time I had them done though.
I do know that the small airways are the hardest to reverse inflammation in, how would inflammation in the smaller airways be treated, or is it not any different? Or is it one of those things that can be just left alone?
just wondering.. can someone have large airway inflammation but not smaller airways? which starts first in an asthma flare up- large or small airways?

Re: can asthma be just smaller airways in general?

I know a little bit about our small airways from asking questions. I go to an allergy and asthma specialist who is into asthma research, so I trust her opinion. My asthma shows that my large airways are pretty normal, but my small airways are about 50% of normal. When I first started treatment they were at 30%, but I have been on Advair for about 6 months and they have increased that much. The small airways are usually where asthma shows up first and more significantly. They are very small and thus when there is inflammation it shows up dramatically. I hope my that in time I will get closer to normal, but she didn't seem that concerned. She said I might have some irreversability. I probably had asthma for awhile before I was diagnosed. However, I live normally. I have energy and even jog a little for exercise whithout much problem. My peak flow is great even a little above normal. I plan to continue with the course of medication she has given me and hopefully I will not get worse. Exercise has benefited me and losing weight. Maybe its because when there is excess fat around the diagphram, it presses up against the lungs? I do have allergies that I treat also. Hope this helps.

Re: can asthma be just smaller airways in general?

Sorry about the duplication. By the way, Blondee, you asked how do you treat small airway inflammation? The same way you treat large airway iflammation. I have heard that some medication that starts with a "Q" is a little better. I'm sorry, I can't remember the name

Qvar has smaller particles that reach the smaller airways. It kind of has a funny taste to it, but if it helps, it helps.
