Chronic renal failure (CRF), also known as chronic kidney disease (CKD), is a progressive reduction of functioning renal tissue such that the remaining kidney mass can no longer maintain the body's internal environment. Early in septic shock, most patients have sinus tachycardia and, by definition, decreased blood pressure (<90 mm Hg systolic, a decrease of ≥40 mm Hg from baseline systolic pressure, or mean arterial pressure <65 mm Hg; Table 108-2). However, it is difficult to use PI to define tissue hyper-perfusion (lack of comparison standard), and this has not been investigated. What does Perfusion mean? . Definition.

It might serve for a more accurate assessment of stroke outcome prognosis and definition of flow-volume mismatch. If it persists, it can cause oxygen deprivation, a condition termed "ischemia," and it also deprives the tissue of needed nutrients and waste disposal. The perfusion index varies depending on patients . In the case of renal perfusion assessment, a renal blood flow scan can . Generally, it should be conceptually thought of as "the area of the brain with reduced perfusion" minus the "infarct core".

Fat is less perfused, made up of the adipose tissue. This is called a perfusion defect and usually represents myocardial ischaemia. Perfusion. In the process of perfusion, blood moves its way out from the heart, through a network of arteries, and into the smallest blood vessels in the body, the capillaries.As the blood flows through the capillaries, it brings vital nutrients to the tissues of the body, and helps to sweep away waste.

Cerebral perfusion pressure, or CPP, is the net pressure gradient causing cerebral blood flow to the brain (brain perfusion).It must be maintained within narrow limits because too little pressure could cause brain tissue to become ischemic (having inadequate blood flow), and too much could raise intracranial pressure (ICP). On CT perfusion the ischemic penumbra has been variably defined using a combination of parameters. Antonyms for tissue perfusion.
