Some time ago, BLF printed a series of three photographs in their magazine , which I have pinned up in the kitchen, entitled "Positions to ease breathlessness." The first shows a man standing, leaning forward , and holding on to the the back of a chair , so that his back is slightly arched, The second one shows the same man sitting down on a chair, again slightly forward with arched back , with elboes on his knees, and the third picture shows him sitting at the table, leaning forward with his arms crossed on a pillow, and his head resting on his arms , in a sort of "Sleep" position" - and again his arched back to achieve this position, So the question is, do the lungs perform better in an Arched position rather than in an upright position when standing virtical ?.These positions help me when I've got to the puffing stage, for whatever reasen, and I 've found when coughing up mucus leaning over a table with a bowel, hands on table to steady yourself, - again , this arched position of the back, helps the mucus to rise up easier than keeping a straight back, and splutttering into a tissue or handkerchief, hence not so much against gravity . - Any views folks? - and if hav'nt tried these positions - have a bash - you've nothing to lose, except that damned mucus, which you don't want anyway , and some good air if it does work for you ! .-Best of luck - Vittorio.
