What indicates adequate tissue perfusion?
Popular biomarkers of tissue perfusion such as serum lactate and central venous oxygen saturation are indicators of global tissue perfusion.
What causes poor tissue perfusion?
Inadequate perfusion to the extremities refers to decreased arterial blood flow to the extremities. This can be due to a sudden embolic event obstructing arterial flow, or a chronic obstructive process leading to decreased arterial flow to the extremities.
How does low cardiac output affect other body systems?
