متن کاملOxygen 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 ...
متن کاملThe impact of an hematocrit of 20% during normothermic cardiopulmonary bypass for elective low risk coronary artery bypass graft surgery on oxygen delivery and clinical outcome – a randomized controlled study [ISRCTN35655335]
INTRODUCTION Cardiopulmonary bypass (CPB) induces hemodilutional anemia, which frequently requires the transfusion of blood products. The objective of this study was to evaluate oxygen delivery and consumption and clinical outcome in low risk patients who were allocated to an hematocrit (Hct) of 20% versus 25% during normothermic CPB for elective coronary artery bypass graft (CABG) surgery. M...
متن کاملLactate and venoarterial carbon dioxide difference/arterial-venous oxygen difference ratio, but not central venous oxygen saturation, predict increase in oxygen consumption in fluid responders.
OBJECTIVES During circulatory failure, the ultimate goal of treatments that increase cardiac output is to reduce tissue hypoxia. This can only occur if oxygen consumption depends on oxygen delivery. We compared the ability of central venous oxygen saturation and markers of anaerobic metabolism to predict whether a fluid-induced increase in oxygen delivery results in an increase in oxygen consum...
متن کاملThe Effect of Controlled Breathing Exercises on Anxiety and Arterial Oxygen Saturation in Chronic Obstructive Pulmonary Disease
Introduction: Anxiety is one of the common symptoms and complications in patients with chronic obstructive pulmonary disease that increases readmission and decreases the quality of life in these patients. Objective: This study aimed to determine the effect of controlled breathing exercises on Anxiety and Arterial Oxygen Saturation in chronic obstructive pulmonary disease in the intensive care u...
