In the past, the extended corresponding states approach to fluid property prediction has been restricted to Ž . non-polar fluids e.g., hydrocarbons and some common non-polar inorganics due to the lack of an accurate way to predict the required shape factors. In this work, a new predictive method to obtain shape factors for the Ž . extended corresponding states theory ECST has been developed whi...

Coexistence curves of square-well fluids with variable interaction width and of the restricted primitive model for ionic solutions have been investigated by means of grand canonical Monte Carlo simulations aided by histogram reweighting and multicanonical sampling techniques. It is demonstrated that this approach results in efficient data collection. The shape of the coexistence curve of the sq...

Fluid management has been a vital part of routine clinical care for more than 180 years. The increasing number of available fluids has generated controversy about the optimal choice of resuscitation fluid. In this review, we provide a critical overview of the different fluids available, their composition, the relevant physiology as well as the published evidence on clinical outcomes to guide th...

We review quantum Monte Carlo results on energetic and structure properties of quantum fluids adsorbed in a bundle of carbon nanotubes. Using realistic interatomic interactions the different adsorption sites that a bundle offer are accurately studied and compared in some cases with strictly one-dimensional geometries. The study is performed quite extensively for 4He and restricted to the inner ...

OBJECTIVES This study aimed to characterize volume profiles and their differences in heart failure (HF) patients with preserved (HFpEF) and reduced (HFrEF) ventricular systolic function. BACKGROUND The extent and distribution of volume overload and the associated implications for volume management have not been studied in decompensated HFpEF compared with HFrEF. METHODS Total blood volume (...

The system of equations obtained from the conservation of multiphasic fluids in porous media is usually approximated by finite volume schemes in the oil reservoir simulation setting. The convergence properties of these schemes are only known in a few simplified cases. The aim of this paper is to present some new results of convergence in more complex cases. These results are based on an adaptat...

Investigations were conducted (1) to measure the steady state compartmentation of body fluids and (2) to assess the efficacy of blood volume and pressure maintenance during haemorrhage-induced hypovolaemia in the pond turtle, Pseudemys scripta elegans. The pre-haemorrhage blood volume, as determined by tracer dilution of 51Cr-labelled erythrocytes, averaged 6.89 +/- 0.33% of the body mass, and ...

Standard therapy forms the basic foundation for care of dogs with glomerular disease, as it is herein recommended for use in all affected animals regardless of causation of the disease. Consensus recommendations target the evaluation and management of proteinuria, inhibition of the renin-angiotensin-aldosterone system, modification in dietary intake with special consideration for those nutrient...

Background: The mainstays of early treatment in septic shock (antibiotics, infection source control, lung protective ventilation, and aggressive volume resuscitation) remain effective. However, although early goaldirected volume resuscitation and a target central venous pressure (CVP) of 8 to 15 mm Hg has become accepted practice, exactly how much fluids to administer or when to stop has yet to...

This study aimed to determine the minimum discard volume from central venous catheters (CVCs) to avoid dilution or contamination from flush or IV fluids. In 93 adult patients with CVCs, minimum discard volume findings were 9 ml for tunneled and 6 ml for nontunneled catheters. Nurses who obtain samples from CVCs are uniquely positioned to minimize blood loss from sampling.
