Background: Fluid status assessment and management post coronary artery bypass grafting (CABG) is a clinical challenge. The study aimed to establish whether central venous pressure (CVP) ultrasound measures of respiratory variability inferior vena cava (IVC) diameter might predict fluid responsiveness in mechanically ventilated patients after CABG.
 Methods: This comparative included 200 c...

OBJECTIVES Exposure to various stressors is known to result in sensitization to psychostimulants, a state related to the psychostimulant dependence and addiction. It has been shown in some studies that the rise in corticosterone (CORT) concentration is indispensable for both the induction and the expression of behavioral sensitization. Therefore, it might be suspected that behavioral hyposensit...

The two classical hard problems underlying the security of lattice-based cryptography are the shortest vector problem (SVP) and the closest vector problem (CVP). For SVP, lattice sieving currently has the best (heuristic) asymptotic time complexity: in high dimensions d, sieving can solve SVP in time 2, using 2 memory [Becker– Ducas–Gama–Laarhoven, SODA’16]. The best heuristic time complexity t...

Background: The diagnosis and treatment of critically sick patients depend on an accurate evaluation intravascular volume status. An intrusive tool utilized for this is central venous pressure (CVP). Aim the study: In present investigation, status severely ill was evaluated using noninvasive Inferior Vena Cava (IVC) diameter Collapsibility Index (CI) measurements in ICU its link with CVP. Metho...

BACKGROUND Initial fluid resuscitation is an important hemodynamic therapy in patients with septic shock. The Surviving Sepsis Campaign Guidelines recommend fluid resuscitation with volume loading according to central venous pressure (CVP). However, patients with septic shock often develop a transient decrease in cardiac function; thus, it may be inappropriate to use CVP as a reliable marker fo...

Spaceflight-associated neuro-ocular syndrome (SANS) involves unilateral or bilateral optic disc edema, widening of the nerve sheath, and posterior globe flattening. Owing to flattening, it is hypothesized that microgravity causes a disproportionate change in intracranial pressure (ICP) relative intraocular pressure. Countermeasures capable reducing ICP include thigh cuffs breathing against insp...

Customer engagement processes introduced in energy network regulation Britain have incentivised networks to think beyond economic efficiency. To this end, the regulator a new incentive: Consumer Value Proposition (CVP), allowing companies use monetised metric gain financial reward should their investments show additional social and environmental value for customers. Through case study of RIIO2 ...

Cost–volume–profit (CVP) analysis is a widely used decision tool across many business disciplines. The current literature on stochastic applications of the CVP model limited in that studied under restrictive forms Gaussian and Lognormal distributions. In this paper we introduce Mellin Transform as methodology to generalize modeling problem. We demonstrate versatility using transform problem, pr...

This article describes a simple, new technique using ultrasound (US) to estimate central venous pressure (CVP). The sonographic patterns of the internal jugular vein (IJV) with a low, normal, and elevated CVP are also described. Although bedside visual inspection of the height of the jugular veins as an estimate of CVP has been an integral part of the physical examination, its major limitation ...
