    Abstract

    Previous studies using transcranial Doppler sonography have suggested that cerebral circulation is preserved relative to cardiac output during normotensive hypovolaemia (NTH). We have further investigated the cerebral autoregulatory responses to hypovolaemia using using MRI measurements of total cerebral blood flow combined with graded levels of lower body negative pressure (LBNP) to induce steady state central hypovolaemia.
