segment hypoperfusion was scored in terms of decreased scintigraphic activity using a four point ordinal scale (0 = no hypoperfusion, 1 = mild hypoperfusion, 2 == moderate hypoperfusion and 3 = marked hypoperfusion). Because some anatomic locations are represented in more than one Figure 1.

hypoperfusion in the left lung with a second defect in the right upper lobe. The discordance between the patient’s clinical condition, specifically the lack of tachycardia or tachypnea, and the striking global hypoperfusion of the left lung prompted further evaluation with a CT angiogram. The CT angiogram

https://info.5y1.org/hypoperfusion-definition_1_a6cab3.html
A. Hypoperfusion (shock) is the inadequate delivery of vital oxygen and nutrients to body tissues, which left unchecked will result in organ system failure and death. B. No matter the initial cause, the final common pathway of shock is inadequate cardiac output.

problematic when it results in hypoperfusion of vital organs, with the consequent reduction in delivery of oxygen and nutrients. For example, a systolic blood pressure of less than 70mmHg can lead to permanent brain or renal damage. There has been discussion as to whether hypotension is a disease or a normal physiological state. Some of this ...
Orthostatic Cerebral Hypoperfusion Syndrome
orthostatic cerebral hypoperfusion may exist without orthostatic hypotension in sizeable number of patients with orthostatic symptoms. This study follows the above observation and defines orthostatic cerebral hypoperfusion syndrome (OCHOs). Underlying hypothesis being tested is that OCHOs is a …
Chronic cerebral hypoperfusion and impaired neuronal ...
chronic cerebral hypoperfusion is lower than that found in acute cerebral ischemia, suggesting that duration as well as severity of ischemic insult determines cellular viability. Chronic hypoperfusion may lead to a noninfarctional state with impaired neuronal function, a category of chronic cere-bral ischemia not previously identified. (Stroke ...

significantly improved by providing a more liberal definition of hypotension, which may provide an earlier and better indicator of blood volume loss and impending circulatory collapse. For this reason, we hypothesized that physiologic hypoperfusion and mortality outcomes classically associated with hypotension would be manifested at SBPs 90 mm Hg.

blood pressure cannot be used to rule out shock, an abnormally low blood pressure may be all that is needed to document hypoperfusion and explain a patient's shock state. The presence of shock is more likely to be occult, however, and to require more indepth investigation and utilization of advanced hemodynamic monitoring techniques.

hypoperfusion as a causal factor in ischaemic stroke, separately or as a contributing factor in embolic stroke, could have important consequences for the care and management of patients,3 and should facilitate research directed at improving the fl ow state of the brain to improve outcome in patients with haemodynamic stroke.
