What is this article about?
Absolute hypovolaemia is the term used to describe the loss of volume of fluid from the body (e.g. during haemorrhage). Relative hypovolaemia is the term used when there is shifting or inappropriate redistribution of body fluids within the body (e.g. major burn trauma). When there is significant acute volume loss or redistribution of body fluid, the patient is at risk of hypovolaemic shock.
