Aim and background : Hemodynamic monitoring of critical patients in intensive units is the cornstone of care. It constitutes an extensive part of care and is helpful in determination of the causes and the response to treatment of hemodynamic instability. Aim of this review articale is to investigate of the Non invasive hemodynamic monitoring in critical care units. Materials and Methods:61 art...

BACKGROUND AND PURPOSE Repetitive motor tasks that produce sustained neuronal activity in the sensorimotor cortex produce transient neuronal activity in subcortical regions. We tested the hypothesis that a reference function modeling a transient hemodynamic response would more reliably detect activation in the basal ganglia than would a conventional reference function, which models a sustained ...

Background: Tracheal intubation and direct laryngoscopy are powerful noxious stimuli that can elicit sever hemodynamic responses. These hemodynamic responses should be attenuated by appropriate use of premedication, smooth induction of anesthesia and rapid tracheal intubation. Gabapentin and pregabalin have been suggested in several studies to be efficient. Gabapentin is an antiepileptic drug a...

A method for detecting significant and regionally specific correlations between sensory input and the brain's physiological response, as measured with functional magnetic resonance imaging (MRI), is presented in this paper. The method involves testing for correlations between sensory input and the hemodynamic response after convolving the sensory input with an estimate of the hernodynamic respo...
