The reduction in RV preload and the increase in RV afterload both lead to a decrease in RV SV, which is at a minimum at the end of the inspiratory period. The inspiratory reduction in RV ejection leads to a decrease in left ventricular filling after a phase lag of two or three ...
Oxygen delivery is primarily dependent on cardiac function and is therefore sensitive to changes in myocardial contractility, preload and afterload. However, matching oxygen delivery to metabolic activity requires circulatory adjustments and normal transfer kinetics. This article will discuss the regulation ...
Changes in RV functions lead to significant modifications of the overall hemodynamics, affecting also LV output due to a decreased preload. To the best of our knowledge, there is not such a previous engineering work aimed at understanding the hemodynamic implications of the development of RV ...

Lactate (La−) has long been at the center of controversy in research, clinical, and athletic settings. Since its discovery in 1780, La− has oft
The mantra of "preload, afterload, contractility, heart rate and rhythm" is repeatedly used on ICU rounds as hemodynamic principles are applied to complex patients. However, translating these concepts from the physiology laboratory to the clinical setting is challenging. During the past decade, two ...
Cardiac output is the amount of blood the heart pumps in 1 minute, and it is dependent on the heart rate, contractility, preload, and afterload. Understanding of the applicability and practical relevance of each of these four components is important when interpreting cardiac output values. In ...
