2015B · VIVA 1
This Viva tested the candidates understanding of the immediate and delayed response to a modest amount of blood loss (approx 10% blood volume). Candidates were expected to describe the volume receptors, barorecepetors and renin-angiotensin system. The viva went on to consider the mechanism amd limitations of automated non-invasive blood pressure (DINAMAP) and coronary artery blood flow and its regulation.
