EFFECTS OF POSTURE ON PLASMA VOLUME AND SOME BLOOD CONSTITUENTS

AUTOR(ES)
RESUMO

When the posture was changed from horizontal to vertical, or the reverse, the alteration in plasma volume and in the levels of haematocrit, haemoglobin, and plasma protein was much greater in patients with oedema or low plasma protein or albumin concentrations (“the pathological group”) than in patients without these abnormalities (“the control group”). This larger fluid shift, and the larger concentration changes dependent on it, are explained in terms of Starling's hypothesis.
