Increased peripheral vascular resistanc.Sympathetic activation, which has multiple effects:.Decreased vagal stimulus thus increased heart rate.Baroreflex activation and chemoreceptor activation.Hypovolemia and cardiovascular compensation.Loss of 2000ml of blood = 40% of the circulating volume = severe haemorrhagic shock.Loss of 1000ml of blood (20% of the total circulating volume) in a 70kg subject represents most of the stressed volume.Staging of blood loss is in terms of % of circulating volume lost:.The effects of the loss of actual haemoglobin is mentioned in cardiovascular response to isovolaemic anaemia, and the haematopoietic recovery from blood loss is discussed in the chapter dealing with the production of red blood cells. haemorrhage', and those are lovingly detailed in the chapter on the cardiovascular response to haemorrhage and hypovolaemia. Fortunately, there's plenty of non-specific categories, and they cover the area in substantial granularity. Section G6(i) talks about 'the response of the circulation to. Weirdly there is no specific category for this in the syllabus.

It has come up a couple of times, as the college has asked direct questions about 'what happens when you lose X amount of blood?', specifically in Question 2 from the second paper of 2009, and Question 11(p2) from the first paper of 2008. In this specific scenario, the movement of the body fluids is out of the body. This chapter is relevant to Section I1(i) of the 2017 CICM Primary Syllabus, which expects the exam candidates to 'explain the distribution and movement of body fluids'.
