Monitoring Preload Performance
1999Reconstruction of State Highway 29 (STH 29) in north central Wisconsin was complicated by two separate deposits of compressible peat and organic silt within the highway right-of-way. The deposits ranged from about 3 to 11 meters in thickness over about 900 meters of the reconstruction alignment.

Preload is the “load before the heart”. It is determined by the venous retum and is entirely dependent on intravascular volemia. Preload is measured during the end-diastole; it is defined as “the force acting to stretch the left ventricular fibers at the end of diastole and to determine the maximal resting lengths of the sarcomeres”.

Acute Preload Effects of Furosemide
Chest, 1990Acute preload effects (as reflected by the pulmonary capillary wedge pressure [PCWP]) of an intravenous furosemide bolus were studied in 33 patients. In those patients receiving no vasoactive drug and in those receiving predominantly preload reducing agents, there was an initial rise in PCWP up until 15 minutes followed by a diuresis-induced fall in ...

Plunging into preload and afterload
Dimensions of Critical Care Nursing, 2001Tools for teaching new nurses surround you in the intensive care unit. This article presents a simple exercise using readily available supplies to help nurses gain a solid understanding of preload and afterload.

Venous modulation of ventricular preload
American Heart Journal, 1992The objective of this discussion has been to describe a simple conceptual model of the circulation that emphasizes the role of the venous capacitance vasculature and is based on simplified vascular pressure-volume relationships. First, it is hoped that this approach will avoid some of the misunderstandings and contradictions that have resulted from an ...

The Veins and Ventricular Preload
1993A simple model of the systemic circulation is presented in which the heart pumps blood out of a venous reservoir into an arterial reservoir. The arterial and venous reservoirs, which have different compliances, are separated by the systemic vascular resistance.

Preload Reduction Therapies in Heart Failure
Heart Failure ClinicsPreload reserve represents an important concept in the normal physiologic responses of the body to meet the changing metabolic demands. The recruitment of preload in healthy patients leads to an increase in effective circulating blood volume with a concomitant increase in cardiac output.
