      No significant correlations were found between peripheral and myocardial microcirculatory beds for either resting flow, hyperemic flow, or flow reserve in any of the groups (r2,0.1, P5NS). Conclusions—The peripheral perfusion responses to transient forearm ischemia do not correlate with dipyridamole-induced myocardial hyperemia.

      With inadequate systemic perfusion there is usually an initial loss of blood flow and pressure to less crucial organs (e.g. skin and gastro intestinal system) in order to maintain flow to more vital organs (e.g. brain and heart). Indications Contraindications Complications

We found that pa-tients who failed to normalize their capillary refill time, PI and peripheral tissue oxygenation during early treatment had a worse outcome. These findings could have implica-tions for the treatment of critically ill patients with ...

      Introduction: The peripheral perfusion index (PI) is a noninvasive numerical value of peripheral perfusion, and the transcutaneous oxygen challenge test (OCT) is defined as the degree of transcutaneous partial pressure of oxygen (PtcO 2) response to 1.0 FiO 2. The value of noninvasive monitoring peripheral perfusion to predict outcome remains

The tem-perature gradients peripheral-to-ambient (dTp-a) and central-to-peripheral (dTc-p) can better reflect cutaneous blood flow than the skin temperature itself. Considering a

Localized alterations in the balance between arterial and venous supply are frequently seen as perfusion ab-normalities at contrast-enhanced CT and MRI.

      The peripheral perfusion index is a potential noninvasive alternative to evaluate SV. The aim of this study is to investigate whether changes in perfusion index during an intraoperative EEOT can predict the response to uid administration in patients undergoing lung-protective ventilation (tidal volume 7 ml/kg predicted body weight).

Cardiac output creates central perfusion. • Local/Tissue perfusion: the volume of blood that flows through arteries and capillaries to the target tissues . Risk Factors:
