This came up in Question 13.1 from the second paper of 2012. It was an odd question: no special insight was interrogated; the trainees were asked to simply list the haemodynamic assessment techniques which were known to them. The college answer dutifully performed this task. No attempt was made to comment constructively on the utility of any of the techniques, or to classify them systematically. The techniques appeared to be listed from least invasive to most invasive, and some were labeled as "experimental", but beyond that little processing occurred. The list below is an attempt to improve on this. Its organisation is derived from David J. Sturgess' chapter ("Haemodynamic monitoring") from Oh's Manual. Given the fondness of the examiners for this book and its various little blue boxes, it seemed like a sensible starting point.
Anyway, without further ado, a dumb but systematic list would look like this:
Static indices of fluid responsiveness
Dynamic indices of fluid responsiveness
Assessment of circulatory efficacy
Assessment of microcirculation
