Check out my new walking jacket.
I can’t tell you how long Ive searched for a sleeveless jersey or jacket with pockets, that I could wear on cold days or long training walks and races without over-heating. As a marathon walker with major health issues, I also have to carry tons of stuff with me, but I hate wearing those bulky packs around my waste.
Well, I think I finally found the perfect solution. It’s called the “Thermal Velocity Vest” made by Specialized (the Bike people). This vest/jacket has pretty much everything I want in a cold weather training top. It has a large zippered pocket on the rear, and a sleek breast pocket on the front. But, what makes this vest special, is that it’s made of a breathable material to keep you cool, and at the same time , fits like a wet suit to keep your core body temp warm. And because it’s a vest, your arms can move freely, which is really important when you’re fitness walking or racewalking . I think it will work out nicely for training on those cold days or for walking a course like the Boston marathon, where the temperatures and winds can fluctuate so dramatically .
A little pricey as far as vests go, but I think worth it. If I’m breathing OK this morning, I’m gonna try it out.
Last week after finding out just how damaged my lungs really are, the only thing going through my head was..WHY? All of the assumptions I had made about my asthma throughout the years, suddenly didn’t seem to make sense anymore. I was beginning to wonder if I really ever had asthma at all? Maybe I just thought it was asthma, when it was actually something totally different? These are the crazy things that were going through my head. I had a ton of questions I desperately needed answered , and since she knows my lungs inside out ( literally) , who better to ask than Dr Wenzel.
Well, not only did she take the time to answer all of my questions, but the answers she gave ….made total sense.
I’m posting some of that discussion here, because I think it might help others out there who are in a similar situation. At the very least, it makes a great refresher course for the RT’s out there.
******************************************************
[Steve ] Because my larger airways are so scarred and stiff, does that mean that they ‘re incapable of clamping up or spasming or narrowing? [Dr. Wenzel] No, not completely, but certainly will be harder to spasm.
[Steve] If that’s the case, and my larger airways are not clamping down, when I have an exacerbation, is it the smaller airways that are reacting? [Dr.Wenzel] Yes, they most certainly are likely to be and because it is also likely that they are narrower to begin with, just a little spasm COULD effect it a lot.
[Steve] I thought there was no smooth muscle in the smaller airways? [Dr.Wenzel] There IS smooth muscle in your small airways. But, you probably ALSO have “Scarring”/fibrosis in those airways which probably leaves them normally much narrower than normal small airways. Just a little mucus or spasm and they will close.
[Steve] You mentioned earlier that I might not actually have chronic inflammation of my airways. If there’s no inflammatory process going on, or no smooth muscle spasm going on, what causes the obstruction or air flow limitation when I flare-up? [Dr.Wenzel] See answers above. In addition, you likely have “loss of alveolar-airway attachments”. The alveolar septae attach to the outside of the small airways and actually help to “tether” the airway open. When those get destroyed, as we think they do in SEVERE asthma, that tendency to PULL the airway open from the outside is lost.
If my airways are non twitchy or non-reactive because they are so stiff, how is it that I can have severe asthma exacerbations that land me in the hospital and sometimes even on a ventilator? [Dr. Wenzel] Your lungs (I think) are very stiff and when you have an attack your work of breathing becomes VERY BIG. That is why your CO2 increases. In addition, you did have a couple of attacks where your lactate levels did increase… that also goes along with your breathing VERY HARD and causing your muscles to start breaking down.
[Steve] If my airways are so damaged, why do I respond, and even partially reverse, with certain bronchodilators and steroids.[Dr. Wenzel] Although you likely don’t have much inflammation, the little that is there (plus some edema) reverses with the steroids. The bronchodilators likely just relax your smooth muscle enough to have an effect, albeit not a big one!
[Steve] Do I have any elements of COPD or Emphysema? [Dr.Wenzel] NO you don’t have COPD OR EMPHYSEMA!!!!
[Steve]Isn’t that generally the course that asthma takes over the long term? [Sally] NO!!! ASTHMA ALMOST NEVER BECOMES EMPHYSEMA…unless you smoke!
[Steve] Regarding my FEV1s, I think the reason I got a 50% reading that one time, was because I exhaled less forcefully during that particular manover ( I was still sleepy from the bronchoscopy). For some reason, when I blast out as hard and as fast as I can, I get slightly lower numbers. ( I think because my airways are narrowing too fast?) [Sally] YES, that is most certainly the case. There is a FORCED vital capacity and a SLOW vital capacity (meaning just that, that you exhale SLOWLY from Total lung capacity to residual volume) It IS likely that your SMALL AIRWAYS do collapse when you exhale fast due to the external force on the airway being greater than the force holding them open during expiration (when you have negative pressures in the airways themselves) .
And finally, there was this….
[Steve] BTW…..The wager we had regarding me being able to ever blow a 50% FEV1 as a result of using Qvar , was that you would get a new set of golf clubs. [Sally] hee-heee… I expect only the finest clubs when I get you there!
