Video - The Role of the respiratory muscles in dyspnoea and exercise tolerance

Just for those who like to learn .... This video is 47 minutes long but it is very informative.

Published on May 14, 2013

Dr Caroline Jolley, of King's College London, discusses the role of respiratory muscle function in the perception of breathing effort, focusing in particular upon patients with chronic obstructive pulmonary disease (COPD). A neurophysiological model of breathlessness is presented in which disordered lung mechanics and diaphragm weakness, lead to an uncoupling of inspiratory pressure generation and ventilation to create a state of "neuromechanical dissociation" and efferent-afferent mismatch. Finally, Dr Jolley consideres whether inspiratory muscle training might ameliorate this mismatch. The lecture was filmed at Brunel University - London in April 2013 as part of a series of lectures on respiratory muscle training in health and disease.

  • On the video above, if you click on the YouTube word bottom right, to watch on You tube, look on the right hand side of the page for lots more information videos.

  • Hi Blakey

    Some interesting bits, I think it makes the point about breathing technique affecting how breathless we feel, tho much of a bit too technical for me

    This is another youtube piece that I discovered a while back, quite long but it did tell me stuff I didn't know


  • Hi Izzy, yes there are lots of information videos, I saw the pathophysiology of copd too :)
