Blood Flow Measurement: The Cardiac Output and Vascular Resistance
The maintenance of blood flow commensurate with the metabolic needs of the body is a fundamental requirement of human life. In the absence of major disease of the vascular tree (e.g., arterial obstruction), the maintenance of appropriate blood flow to the body depends largely on the heart's ability to pump blood in the forward direction. The quantity of blood delivered to the systemic circulati...

The author alludes in the prefatce that its reviewers would probably not be drawn from the ranks of those to vholom the 1)ook is pa...
متن کاملMeasurement of Flow in Single Blood Vessels Including Cardiac Output by Local Thermodilution
BLOOD flow in single vessels can be measured by direct methods such as rotameter, drop-flow meter, Rein-thermostromuhr, Venturi principle, electromagnetic flow meter and bubble-floAV meter. Such methods are usually characterized by great accuracy, but their applicability is considerably limited in man by the fact that the appropriate vessel must be made accessible. Blood flow in some regions wa...
متن کاملMeasurement of cardiac output.
Float catheterisation of the pulmonary artery was described in The Lancet by Dr R D Bradley (as he then was) in 1964 at a time when invasive circulatory monitoring was almost non-existent outside cardiac surgical units, and ‘intensive care’ was a term barely in use. Cardiac catheterisation was laboratory based and required radiological control: management of acute circulatory crises relied on c...
متن کاملEchocardiographic measurement of cardiac output in rats.
The systematic evaluation of different transthoracic echocardiographic (TTE) methods to determine cardiac output (CO) and the effect of changes in intravascular volume on echocardiographically determined indexes of cardiovascular structure in the rat has not been documented. With the use of 11 Wistar rats, simultaneous echocardiographic and thermodilution measurements of CO were compared at bas...
