Article is all wrong! Orhopnea is when you sit with your arms extended, to make breathing easier! Not as the article says! —Preceding unsigned comment added by 153.19.98.56 ( talk) 11:04, 21 June 2008 (UTC) reply

Orthopnea does make breathing easier but it does so by helping to clear the lungs of edema. Your arms don't have a lot to do with this - it is the sitting that allows gravity to help clear the lungs. Look up the term elsewhere (like a medical book) and if you are convinced you're right please re-educate the entire medical community. 155.37.215.231 ( talk) 01:37, 22 January 2009 (UTC) reply

Orthopnea is any breathing difficulty with posture, not any specific posture. Pulmonological ( talk) 08:00, 28 October 2011 (UTC) reply
