How is it the case that some people can lose significant muscle mass while they are being cared for on the Intensive Care Unit (ICU)? What can practitioners do to help avoid this? How do we integrate a dynamic stimulus and react to new research relating to nasogastric feeding?   In this piece you will hear about a randomised controlled pilot study investigating the effect of intermittent versus continuous nasogastric feeding on muscle mass and function in intensive care unit survivors.   Hugh Montgomery presents with his guest, Dr Angela McNelly, clinical researcher at the ISEH and the UCL Centre for Human Health and Performance.
