Perfusion index as a possible predictor for postanesthetic shivering

Journal of Anesthesia, 2013
Postanesthetic shivering can be triggered by surgical stress and several aspects of anesthetic management and is frequently preceded by a decrease in peripheral blood flow due to thermoregulatory vasoconstriction. As perfusion index correlates with peripheral blood flow, we examined whether perioperative perfusion index, measured using pulse oximetry ...

Correlation of Perfusion Index Change and Analgesic Efficacy in Transforaminal Block for Lumbosacral Radicular Pain

Journal of Clinical Medicine, 2019
Transforaminal epidural injection is used to treat radicular pain. However, there is no objective method of assessing pain relief following transforaminal injection. Perfusion index is a metric for monitoring peripheral perfusion status.

Monitoring Perfusion Index in Patients Presenting to the Emergency Department Due to Drug Use

Journal of Personalized Medicine, 2023
(1) Background: The perfusion index (PI) represents the ratio between pulsatile blood flow and non-pulsatile blood flow in the peripheral tissue. (2) We aimed to investigate the blood pressure perfusion of tissues and organs in ethnobotanical, synthetic ...

The perfusion index of healthy term infants during transition at birth [PDF]

European Journal of Pediatrics, 2015
Perfusion index is a continuous parameter provided by pulse oximetry and might be useful for evaluating hemodynamic changes at birth and identifying transitional problems.

Hepatic perfusion index

Nuclear Medicine Communications, 1992
The reproducibility and accuracy of the hepatic perfusion index (HPI) was examined by consideration of in vitro and in vivo factors. A phantom was used to simulate liver blood flow and data acquired on nine gamma cameras. Dynamic hepatic scintigraphy was undertaken on 28 patients at two centres and values obtained for the HPI.

Application of the perfusion index in obstetric bleeding

The Journal of Maternal-Fetal & Neonatal Medicine, 2016
We assessed the utility of the pulse oximeter perfusion index (PI) in maternal monitoring immediately after delivery.We examined 30 pregnant women without any complications using the Rad7 device at delivery. The correlations between heart rate (HR), systolic blood pressure (BP), oxygen saturation SpO2, PI, Pleth variability index (PVI), shock index and

A model of the hepatic perfusion index in the rat

Nuclear Medicine Communications, 1987
The hepatic perfusion index (HPI) is an indicator of the relative hepatic arterial to total liver blood flow as measured by dynamic flow scintigraphy. Hitherto, accurate assessment of the HPI in small animals has not been possible because of methodological difficulties.

The perfusable tissue index: a marker of myocardial viability

Journal of Nuclear Cardiology, 2003
PTI is a promising technique for detecting viable myocardium. The need for a PET scanner, an onsite cyclotron, and expertise regarding the production and administration of O-15-labeled water and carbon monoxide results in a tool that is only available in a limited number of centers worldwide.

The influence of downstream arterial perfusion parameters on Doppler pulsatility index and resistance index in an in-vitro perfusion model

Vasa, 2006
Background: To investigate in vitro how downstream perfusion parameters influence pulsatility index (PI), resistance index (RI) and their constituting Doppler velocities. Materials and methods: We analyzed the influence of resistance, compliance, reflection coefficient and input impedance on PI and RI in an in-vitro model of arterial flow.
