The use of renal resistive indices (RRIs) for the study of renal microcirculation has in the past
been proposed for the identification of renal organ damage or even to specifically identify …

From growing data from the literature emerges that so-called ecoDoppler “Renal” Resistive
Indexes (RRI) are not only specific markers of kidney damage and indicators of renal …

Circulatory shock is defined as a disorder with evidence of both clinical and biochemical
tissue hypoperfusion, entailing inadequate oxygen utilization by cells, with or without a …

Graded lower-body negative pressure was used to create a hemodynamic response similar
to hemorrhage. Echocardiogram measurements showed a maximal reduction of 32.4% in …

In patients with acute circulatory failure, fluid administration represents a first-line therapeutic
intervention for improving cardiac output. However, only approximately 50% of patients …

Background We reported a case of early detection of peripheral hypoperfusion trough the
evaluation of a new index in intensive care: Renal Doppler Resistive Index (RRI). Case …

Objective. To test if splenic Doppler resistive index (SDRI) allows noninvasive monitoring of
changes in stroke volume and regional splanchnic perfusion in response to fluid challenge …

The spleen is an important immune organ that releases erythrocytes and monocytes and
destroys aged platelets. It also reserves 20–30% of the total blood volume, and its size …

The utility of functional hemodynamics and bedside ultrasonography is increasingly
recognized as advantageous for both improved diagnosis and management of shock states …

Purpose To evaluate the changes in splenic volume during hypovolemic shock and after
recovery by use of multidetector computed tomography (MDCT). Materials and methods We …
