the physio technique i use is called AD, am pretty sure that stands for autogenic drainage. it consentrates soley on the breathing, and u breathe v gently so as not to aggravate the airways, that will make them narrow and renders physio useless.i breath in slowly and fairly deeply, then hold it for a good 3 seconds, then open my mouth really wide (they recommend one of those cardboard peak flow mouthpieces when learning to make sure your mouth is wide open enough) and breath out with a kind of "huuuuh" sound. force the breath out slightly, but not so much that it makes you wheeze. i do about 5 breaths per cycle, and however many cycles it takes. holding your breath gives the air time to disperse fully around the lungs, and in doing so it will move behind some of the mucus plugs clogging certain airways. then when u breathe out, the air moves the mucus upwards, and when it gets to the top it is easy to clear!! personally i usually find no matter how gently i do physio i still get wheezy, but this is the best one for me, and i tend not to clear at the time, but lots of stuff comes up later when my airways have settled down. hope that helps! <img src="i/expressions/face-icon-small-smile.gif" border="0">
