Regulation of Amniotic Fluid Volume
Placenta, 2007Water arrives in the mammalian gestation from the maternal circulation across the placenta. It then circulates between the fetal water compartments, including the fetal body compartments, the placenta and the amniotic fluid. Amniotic fluid is created by the flow of fluid from the fetal lung and bladder.

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 ...

The Physics of Fluids, 2019
Drop formation and detachment involve large topological changes, including the formation of a fluid neck that thins down due to surface tension-driven flows, and at the neck pinch-off, properties like Laplace pressure display a finite time singularity ...

Volume-of-Fluid Model for Simulating Vapor–Liquid Phase Change in a Solar Still
Journal of thermophysics and heat transfer, 2018In this paper, a volume-of-fluid model is developed to simulate the vapor–liquid phase change in a modified solar still equipped with a porous layer in its basin.

Measurement of amniotic fluid volume
Vrach, 2023The qualitative or semi-quantitative assessment of amniotic fluid volume (AFV) is a standard component of every ultrasound in the second and third trimesters of pregnancy. AFV abnormalities are associated with various pregnancy complications. In clinical practice, ultrasound (US) assessment of AFV is used in conjunction with other clinical and ...

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 ...

Acoustic Estimation of Neck Fluid Volume
Annals of Biomedical Engineering, 2014Recently we showed that fluid accumulation in the neck can narrow the upper airway (UA) and increase its collapsibility, which may exacerbate obstructive sleep apnea (OSA). However, the available methods for measuring neck fluid volume (NFV) are inconvenient and expensive.

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 ...

Estimates of Extracellular Fluid Volume of Myocardium
American Journal of Physiology-Legacy Content, 1955The extracellular fluid volume of the myocardium was determined in nephrectomized cats using sucrose as a reference material. This was allowed to equilibrate for one day before analysis. The chloride space, sodium space and an extracellular fluid volume based on the Conway-Boyle hypothesis were also determined.

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).
