The measurement of segmental venous flow by an indicator dilution method.
Several methods have been evolved for the measurement of venous flow in animals, but most have a limited application in man as they involve exposure of the appropriate blood vessel. These methods include the Ludwig type stromuhr (Tigerstedt, 1892), the thermostrontuhr (Rein, 1928; Schmidt and Walker, 1935; Shipley et al., 1942), the bubble flow meter (Soskin et al., 1934; Brunner, 1948), the di...
متن کاملApplication of a Constant Indicator Dilution Method to the Measurement of Local Venous Flow.
• Many investigations of the cardiovascular system require estimations of regional or single vessel blood flow. Although direct methods ' have been devised for this purpose, most have a limited application in man because they involve exposure of the appropriate blood vessel. When multiple and frequent flow estimations over a long period are desired in experimental animals, repeated exposures of...
متن کاملRECLAMATION OF SOME SODlC SOILS BY THE HIGH SALT WATER DILUTION METHOD
, Abstract Results of the laboratory reclamation of four sodic soils by the high salt water dilution method are reported. The exchangeable sodium percentage (ESP) of all soils was decreased by leaching with solutions of decreasing sodium but constant calcium concentration. Although a final leaching with water of low electrolyte concentration (EC,, < 100 micromhos/cm) did not produce a rapid dec...
متن کاملIntroduction to Salt Dilution Gauging for Streamflow Measurement Part IV: The Mass Balance (or Dry Injection) Method
In part one of this series, Moore (2004a) introduced the general principles of stream gauging by salt dilution. In subsequent articles, Moore (2004b, 2005) described techniques of constant-rate injection and slug injection using salt in solution. This is the final article in the series and details the “mass balance method.” Originally described by Elder et al. (1990), the mass balance method di...
متن کاملMeasurement of milk intake by deuterium dilution.
In 14 studies, each lasting seven days, on eight bottle fed infants milk intake was measured by deuterium dilution and by weighing the formula consumed and oral losses. Mean (SD) milk intake was 829 (108) g/day when measured by isotope dilution and 837 (98) g/day when measured by direct weighing, giving a mean difference between methods of 1.0 (5.0)%. Thus the stable isotope procedure is a pote...
