Impact of Systemic Vascular Resistance on the Accuracy of the Pulsioflex Device.

07:00 EST 5th January 2017 | BioPortfolio

Summary of "Impact of Systemic Vascular Resistance on the Accuracy of the Pulsioflex Device."

The accuracy of currently available devices using pulse contour analysis without external calibration for cardiac index (CI) estimation is negatively impacted by hyperdynamic states, low systemic vascular resistance (SVR), and abrupt changes in SVR. The aim of this study was to evaluate the accuracy of a new device, the Pulsioflex (Pulsion Medical System), in patients undergoing liver transplantation.

Medical and Biotech [MESH] Definitions

The vascular resistance to the flow of BLOOD through the CAPILLARIES portions of the peripheral vascular bed.

The force that opposes the flow of BLOOD through a vascular bed. It is equal to the difference in BLOOD PRESSURE across the vascular bed divided by the CARDIAC OUTPUT.

The active alterations of vascular wall structures, often leading to elevated VASCULAR RESISTANCE. It is associated with AGING; ATHEROSCLEROSIS; DIABETES MELLITUS; HYPERTENSION; PREGNANCY; PULMONARY HYPERTENSION; and STROKE, but is also a normal part of EMBRYOGENESIS.

A dihydropyridine calcium antagonist with positive inotropic effects. It lowers blood pressure by reducing peripheral vascular resistance through a highly selective action on smooth muscle in arteriolar resistance vessels.

Condition of low SYSTEMIC VASCULAR RESISTANCE that develops secondary to other conditions such as ANAPHYLAXIS; SEPSIS; SURGICAL SHOCK; and SEPTIC SHOCK. Vasoplegia that develops during or post surgery (e.g., CARDIOPULMONARY BYPASS) is called postoperative vasoplegic syndrome or vasoplegic syndrome.
