How much loss of circulating body fluid is within normal compensatory mechanism of body
15% loss
20% loss
30% loss
40% loss
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.
