Independent measurement of oxygen consumption and oxygen delivery

Independent measurement of oxygen consumption and oxygen delivery.

This experiment investigated the relationship between oxygen consumption and oxygen delivery (cardiac output X arterial oxygen content) in an acute canine model. Previous studies investigating this relationship have largely utilized methods in which oxygen consumption and oxygen delivery were each calculated using the same measured variables resulting in mathematical coupling of variables. In t...

Oxygen delivery and consumption: a macrocirculatory perspective.

Severe sepsis is a leading cause of death and resource use throughout the world. This article examines the relationship of oxygen delivery to oxygen use under varying conditions. Topics reviewed include the concept of the critical dissolved oxygen, concerns over shared measurement errors in obtaining estimates of oxygen consumption, seminal articles in this area, and the practice of early goal ...

Validity of Peripheral Capillary Oxygen Saturation and Normal Mixed Venous Oxygen Tension in Measurement of O2 Content

Background The change in venous oxygen saturation occurs earlier, and even its reduction is faster than arterial oxygen saturation. The aim of this study was to validate SvO2 and PvO2 for O2 content measurement in children hospitalized w...
