How much loss of circulating body fluid is within normal compensatory mechanism of body
Further loss of circulating volume overloads the body’s compensatory mechanisms and there is progressive renal, respiratory and cardiovascular decompensation. In general, loss of around 15% of the circulating blood volume is within normal compensatory mechanisms. Blood pressure is usually well maintained and only falls after 30–40% of the circulating volume has been lost.
