Importance of oxygen transport in clinical medicine

Critical Care Medicine
H B HechtmanC R Valeri

Abstract

One or more of the several components of the oxygen transport system may function abnormally in critical illness. Arterial hypoxemia is an important feature of acute respiratory failure. Its prominence may obscure other limitations in oxygen availability such as low cardiac output, anemia, or an increased red cell affinity state. These several components of the oxygen transport system can be influenced by therapeutic maneuvers, but the result may not necessarily be a net benefit. For example, red blood cell transfusion therapy may correct anemia, but increase the red blood cell affinity state so as to adversely affect cardiac function. Treatment programs require consideration of the interaction of these several variables affecting oxygen transport.

Anemia

Anemia develops when your blood lacks enough healthy red blood cells. Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. Here is the latest research on anemia.

Cardiac Aneurysm

Aneurysm refers to a bulge of the wall or lining of a vessel commonly occurring in the blood vessels at the base of the septum or within the aorta. In the heart, it usually arises from a patch of weakened tissue in a ventricular wall, which swells into a bubble filled with blood. Discover the latest research on cardiac aneurysm here.

Aortic Aneurysm

An aortic aneurysm is the weakening and bulging of the blood vessel wall in the aorta. This causes dilatation of the aorta, which is usually asymptomatic but carries the risk of rupture and hemorrhage. Find the latest research on aortic aneurysms here.
