Read the Weiner article.. Bill, You talk about a negative pressure pause, which I did not mean at all.
I understand that, but never the less in using the SIMT device, negative pressure and its effects can not be ignored IMHO. Sorry, my bad writing. I quite see you would be apprehensive about safety aspects with such pauses. The article in Chest is on training muscle coordination and muscle strength by dynamic exercises. This max.
These tests were done and results obtained over a period of 6 months. I thought you admitted to much more rapid changes in symptoms than that. So I’m a bit confused by your attachment to the muscle tone theory. inspiratory pressure is tested statically as representative for progress made but is not meant as a maneuver to help breathing.
OK and so the muscle tone improved, and dyspnea possibly reduced. This might have a calming effect and allow slower respiration to be more comfortable. The article (Chest 1992, 1357-61) by Weiner tells us about coordination of inspiratory muscles being important for suction. Maybe the underlying mechanism is not pressure, as you say, but this would not seem to change the practical outcome.
However hyperinflation is the underlying problem with chronic respiratory disease, so wouldn’t it be better to reduce this, rather than fight it with increased force. You might find this a loosing battle and do more damage by going beyond the elastic limit of the tissue. Fortunately an (side) effect of these tests reduces hyperinflation and also a bronchoprotective (side) effect, in my experience. But in order to make these effects more permanent, other steps need to be taken. See the first paragraph after the summary: "The hyperinflation of the lung flattens the diaphragm, shortens the inspiratory muscles, and places them at a mechanical disadvantage. In addition to the reduced efficiency of the inspiratory muscles, large amounts of pressure work are required to overcome the high airway resistance."
By working your breathing closer to Residual Volume where the diaphragm is not so flat and by concentrating on slow expiration rather than inspiration, these problems do not arise. In fact you should never force the issue as it only compounds the problem, panic (and death) is the usual end result. Weiner’s external resistance puts the diapharagm through its paces quite effectively and produces clinically relevant improvements. See summary: "We conclude that SIMT, for six months, improves the inspiratory muscle strength and endurance, and results in improvement in asthma symptoms, hospitalizations for asthma, emergency department contact, absence from school or work, and medication consumption in patients with asthma."
Weiner himself admits that the real reason for the benefits obtained with SIMT are unknown. My bet is the NP causes the beneficial effects for reasons I have outlined. On the face of it the effect of the exercises is not perfectly clear. Weiner does appear in part to be sticking to the old idea of toughening up the patient so that he can better handle the increased breathing effort in an attack. On the other hand the improvement noted would seem to speak for a general improvement in breathing all the time and – THIS IS THE CRUCIAL POINT – applying nose (or throat) resistance to get the
Yes sniffing also seems beneficial, I have always suggested fast inspiration through the nose. Because it improves hydration and warming! suction. If the upper airways were typically kept in the fully open gulp position then the acquired "diaphragm breathing potential" would simply be wasted
I have experimented with throat restriction, but I find it uncomfortable, and the additional dynamics have no "immediate" added effect. If you must use NP a gentle epiglot obstructed lengthy pause at close to RV is easiest and a SIMTdevice is totally unnecessary. It is a general aim in asthma physical therapy to promote diaphragmatic breathing. This would obviously mean maintaining it between separate exeercise periods, if any, as well.
I don’t believe so much in intermittent practices, good hydration is a continuous requirement and so I prefer something that can become habitual and then you must not mouth breathe during sleep. I really do not know if my "respiratory intellegence" was particulary poor, but in my excruciating attacks in the past, I am reasonably sure now, my only tactic was to gulp in as much air as seemed possible, that is to say with my mouth and throat wide open. My breathing was extremely thoracic. This meant a low suction.
Understandable. As I said SIMT solved my problem (cured my asthmatic but non medicated shortness of breath) by showing me a direct path from the one possible option of taking a reliever puff and getting a sort of sick, guilty pleasure on suddenly being able to take an invigorating diaphragmatic breath by drug usage to the healthy option of using a sophisticated muscular technique. I guess this is or was at one time the dream of half of those here.
Good for you! Putting it more provokingly still: it is as if I have a permanent, safe and healthy ventolin tucked away in my inside. Regards, Richard Friedel
Quite a calming effect I am sure. Good Health. Bill

As for pursed lips breathing. It is taught extensively for asthma in Germany as part of orthodox treatment. However, knowing the hypnotic effect of breathing routines, it might be counter productive.
I woder if you have had much actual exposure to people with advanced emphysema. They do pursed-mouth breathing not because they have been taught, but because that is the only way they can keep air going in and out. It just sort of comes to them that they need to be oxygenated and that this is the only way to accomplish it. Are you an engineer? Larry

Response:
Bill, Firstly congratulations on your success with nose breathing. The key point here seems to be that the medical view that the nose is only for warming, moisturizing and cleaning the air we breathe is a dogma based and just a concession to patients’ feelings. If we assume that negative pressure due to the nose is essential for the efficiency of respiration, everything falls into place. Studies on nasal resistance show that it varies and that the nose tends to "amplify" suction as a starling resistor. But the authors of papers insist on speaking of a collapse of the upper airways. Medical writers also speak of the work of breathing as if it should be minimized. However this springs from a doctrinaire compartmentalization of the body. It is obvious that increasing respiratory effort will, if the diaphragm is working properly, improve hemodynamics and massage the abdominal organs. The following aspects speak for an error in medical theory: 1 It seems an old-fashioned not to say simple-minded approach to nature to more or less decree that the enormous work of nasal breathing of, say, a galloping horse (which cannot breathe through its mouth), is all wasted. What do these people understand by vitality, one might ask. 2 Attempting breathing exercises such as za-zen with mouth instead of the prescribed nose breathing fail miserably. See my posting to sci.skeptic of May on this. 3 Diaphragmatic breathing is promoted by upper airways resistance, because such resistance forces coordination of the diaphragm with other breathing muscles. 4 Common sense speaks for the utility of diaphragmatic breathing not just being a popular error. 5 The unusual amount of attention given by quacks to asthma. This might well mean that conventional asthma treatment is itself not so very sound. As for pursed lips breathing. It is taught extensively for asthma in Germany as part of orthodox treatment.

My understanding has been that pursed-mouth breathing helps when there is over-inflation of alveoli, due most often to destruction of interalveolar walls. This is the picture in emphysema. The overdistention also occurs, reversibly, in asthma. Purse-mouthed breathing obviously works, or you would not see patients with advanced emphysema performing it unconsciously, and of necessity. With airways like this it is necessary that there be slow emptying, or air-trapping occurs. If there is external pressure on the lungs, due to the respiratory motion of the chest wall and the diaphragm, obviously the volume of the lung must also decrease. If this volume change occurs too rapidly for the overdistended alveoli to empty through narrowed airways, that volume change must involve other structures. The air-containing bronchial tree is the only candidate left. the major airways are rigid enough that they cannot collapse, but the smaller airways can, and do, before the lung has deflated. In that circumstance you have alveoli that have no communication with the outside. They then cannot empty and cannot dispose of the CO2 that has been brought to them by the pulmonary circulation. Rapid breathing thus leads to CO2 build-up, rather than to the excess blow-off it will cause in the lung that can empty rapidly. Back-pressure keeps the small airways open long enough for the alveoli to empty, and this is the reason that those with emphysema can still play the oboe but not the trombone (study done with the Concertgebouw Orchestra of Amsterdam 30 years ago).

Response:
I can give you a good breathing excercise. I will also see if I can get the info from the Jewish ( which are you talking about? I am Jewish and contacted the Jewish medical learning center) But with all the medical problems I have especially the pain part the best breathing excercise for your lungs is inhaling as much as you can through your nose and slowly exhale out your mouth.
Opinion : Never breathe through the mouth (in or out) The nose is not just a filter, it also has important heat and moisture exchange properties. As you describe is likely to dry the sinuses and nasal passages in most environments. Atmospheric moisture is usually less important than internally generated moisture (humidity) although perhaps less so in Fl. or the tropics. Bill not an MD. Do it all slowly to expand the lungs to the maximum – Hide quoted text — Show quoted text – hold it briefly and slowly release through the mouth. This I was taught by my pulmonary (actually the one in Tampa, Fl and again here in Coral Springs Fl) It works great. And you do it anytime you want but try to do it at least 3 times a day. In no time you will see a big difference. Oh a hint, if you live somewhere with extreme heat esp. humidity it feels better when you first start in a better environment. If you are dealing with pain, slowly breath in and out Nose and mouth almost like panting. The same way us women are taught for child birth. I do both of these. If you still want me to get the information just say yes. UM MOM Susan Susan, I was asking about breathing exercises, specifically about SIMT. My understanding is that when Bob asked about Buyteko, Jewish hadn’t heard of it. Then they stated they did use breathing exercises, so I wondered which ones they thought had value.

I can give you a good breathing excercise. I will also see if I can get the
info from the Jewish ( which are you talking about? I am Jewish and contacted the Jewish medical learning center) But with all the medical problems I have especially the pain part the best breathing excercise for your lungs is inhaling as much as you can through your nose and slowly exhale out your mouth. Do it all slowly to expand the lungs to the maximum hold it briefly and slowly release through the mouth. This I was taught by my pulmonary (actually the one in Tampa, Fl and again here in Coral Springs Fl) It works great. And you do it anytime you want but try to do it at least 3 times a day.

I have tried breathing out and holding that way as long as comfortable, before I ever saw the name Buteyko. Or I might breathe in through the nose as much as possible, then slowly exhale, and subsequently, though not necessarily on the same breath, breathe out and hold that way. How hot is extreme? Normal temperature inside the lungs would be 37 C, humidity 100%, so breathing air near that temperature shouldn’t irritate the lungs, though somewhat lower temperatures might feel more comfortable.

I checked out your site and I have used this many times. When ever I have to take test that require me to have anesthesia and when I had my resection I had it before to prepare my lungs the 3 times a day while I was recovering in the hospital. I also had it for er visits when I was bleeding and needed transfusion. I don’t remember what my dr order for the med I just know it helped immensely after the 2nd day. It was hard with the resection surgery because of the need of a coughing pillow and it hurt the stomach a lot to cough well move as far as that goes but I had a magic button that helped me not care about the pain its called every 3 minutes of valium and Demerol!

Susan, Thanks for the offer. I was asking because someone asked me about THE BREATHER. http://www.betterairways.com/ It appears that this is regularly given to patients who have had major thoracic surgery. It doesn’t seem like the recommendation has made it from the heart docs to the lung docs yet, but people seem to think it helps after heart surgery. So I got to wondering.

Thanks Bob. One day when my phone isn’t busy from being on the computer, I may try it. Seems like she is a person who could answer many of my questions (since my case is so ODD).

She did return my call immediately though, but we missed each other. Then all hell broke loose with the fire. Here is another information line you can call, if she doesn’t get back to you: http://nationaljewish.org/diseases/d1.html

Did the Doctor from Jewish ever get back to you about the breathing exercises?

JAR, she and I played phone tag, then I emailed her with everyones’ questions on June 6. She was out of the office, then returned to the big fire they had there, so my email has not yet been returned. Here is her website. Call or email her; hopefully you will have better luck than I did. http://nationaljewish.org/faculty/kraft.html
