Measurement of blood flow allows calculation of cardiac output, which enables clinicians to more accurately administer fluids (colloid or crystalloid intravenous solutions) needed to achieve adequate tissue perfusion. (cms.gov)
If the cardiac output does not increase after such administration (a fluid challenge,) this may indicate that the upper limit of beneficial fluid administration has been achieved and that further fluid administration could lead to fluid overload manifest by venous congestion and possible post-operative pulmonary edema (RNAO, 2006).
