Amniotic Fluid Index: Correlation with Amniotic Fluid Volume
American Journal of Perinatology, 1992We calculated the amniotic fluid indexes (AFIs) of 310 women on 459 occasions. Normative data were analyzed and compared with data in several high-risk groups. In the normal gestations there was a progressive increase in AFI with advancing gestation until 32 weeks, after which there was a decline.

Amniotic fluid volume: Fluid dynamics and measurement technique
Seminars in Ultrasound, CT and MRI, 1993Evaluation of amniotic fluid volume is an important aspect of obstetrical ultrasound. Several methods are currently used to describe amniotic fluid volumes. The most common are the subjective assessment of fluid and the semiquantitative methods. The reproducibility of these methods is excellent in experienced hands. Because of the multiple methods used

Fluid Volumes: The Program “FLUIDS”
1993This chapter describes the program FLUIDS. The mathematical model underlying this program contains over 200 variables and describes control mechanisms of body fluid volumes and electrolytes as well as respiratory control mechanisms. This model allows a variety of simulations for conditions such as thirst, fluid loss, exaggerated drinking, carbon ...

The dialysis of small volumes of fluid
The Analyst, 1969A simple, non-metallic closure for small dialysis tubing is described.In a smaller-scale procedure the 5 to 50 µl of solution to be dialysed are placed on a circle of cellophane, 7·5 mm in diameter, held by suction to the upper end of a vertical tube containing water or saline, which may or may not be continuously renewed.

Regulation of Endolymphatic Fluid Volume
Annals of the New York Academy of Sciences, 2001Abstract: Direct measurements of the dispersal of markers in endolymph have failed to support previously established hypotheses of endolymph homeostasis, specifically longitudinal flow, radial flow, and dynamic flow theories. Rather, they suggest that in the normal state endolymph is maintained without a significant involvement of volume flow at all ...

Regulation of Body Fluid Volume
1994Sodium salts are the main osmotically active solutes of the extracellular fluid (ECF). Thus, since body fluid osmolality is regulated by osmoreceptors and ADH release, if the extracellular fluid sodium content changes, then ECF volume will also change (Figure 9.1).

Feasibility of fluid volume conductance to assess bladder volume
Neurourology and Urodynamics, 2007AbstractAimAmbulatory urodynamics has the potential to provide measurements of bladder function during activities of daily living; however, no method of real‐time continuous bladder volume measurement exists. The present study was conducted to determine the feasibility of using fluid volume conductance to continuously assess bladder volume ...

Treatment of canine aspiration pneumonitis: fluid volume reduction vs. fluid volume expansion
Journal of Applied Physiology, 1988The aspiration of gastric acid causes pulmonary edema and hypoxemia. One approach to the management of this syndrome is to raise cardiac output (Qt) and O2 delivery (QO2) to ensure tissue oxygenation (VO2) at the risk of increasing the edema. Another approach reduces the edema by reducing pulmonary microvascular pressure (Pmv) at the risk of reducing ...

To better understand the mechanisms that regulate amniotic fluid (AF) volume, we measured AF volume and the rates of fetal swallowing and urination in 33 pregnant sheep at 124-142 days gestation. In four of five ewes over 9-18 days, the spontaneous changes in amniotic fluid volume correlated positively with urine flow rate and negatively with the rate
