Abstract : Total cerebral blood flow was measured by sampling hydrogen clearance from torcular blood using simple, hydrogen-sensitive, platinum electrodes. The clearance curves in rhesus monkeys were usually biexponential with a mean flow in the slow compartment of 28 ml/100 g per min, a mean flow in the fast compartment of 102 ml/100 g per min and a mean total cerebral blood flow of 52 ml/100 g per min. This method is relatively simple and accurate and constitutes a valuable adjunct to local cerebral blood flow measurements using the same technique.
