Use of Pulmonary Artery Pulsatility Index in Cardiac Surgery

Journal of Cardiothoracic and Vascular Anesthesia, 2020
This study evaluated whether the pulmonary artery pulsatility index (PAPi) collected before and after cardiopulmonary bypass (CPB) is predictive and diagnostic of new onset right ventricular (RV) failure in the elective cardiac surgical population.This was a prospective observational study of patients who underwent cardiac surgery between 2017 and 2019.

Transcranial Doppler Pulsatility Index

Neurosurgery, 2010
Transcranial Doppler sonography (TCD) assessment of intracranial blood flow velocity has been suggested to accurately determine intracranial pressure (ICP).We attempted to validate this method in patients with communicating cerebrospinal fluid systems using predetermined pressure levels.Ten patients underwent a lumbar infusion test, applying 4 to 5 ...

Doppler-Pulsatility Index

Pediatrics, 1983
To the Editor.— The determination of cerebral blood velocity in the newborn infant using transfontanel Doppler ultrasound has been discussed in detail in two recent commentaries.1,2 Whereas the use of the Doppler effect to determine blood velocity is well accepted, it is apparent that considerable controversy exists regarding the ability

Gosling’s Doppler Pulsatility Index Revisited

Ultrasound in Medicine & Biology, 1998
In Doppler sonography, the physiological meaning of Gosling's pulsatility index (PI) as a measure of downstream resistance is still under dispute. We deliver the theoretical derivation of its physiological significance. We present a mathematical model based on the linked theories of critical closing pressure (CCP) and cerebrovascular impedance ...

Homocysteine and pulsatility index in lacunar infarction

Clinical Neurology and Neurosurgery, 2011
To evaluate an association between plasma concentration of total homocysteine (tHcy) and pulsatility indexes (PIs) of cerebral arteries in patients with lacunar infarction (LI), comparing control subjects.Consecutive patients referred to a neurovascular ultrasound laboratory were evaluated from March 2007 to February 2008.
