Peripheral venous pressure waveform.
PURPOSE OF REVIEW The focus of intraoperative monitoring is moving away from invasive monitoring. This has been attributed to procedure time, cost, and the known risks, which include carotid artery puncture, arrhythmia, pneumothorax, and infection. Until recently, the venous system's contribution to the circulatory system has been incorrectly identified as being insignificant. This article summ...
متن کاملAnalysis and Identification of an Intraocular Pressure Waveform
Certain ocular diseases such as glaucoma cause an increase in the internal pressure of the eye, damaging nerves. An implantable pressure sensor would give patients the ability to monitor their own intraocular pressure and then consult a physician if necessary. One device to do this has been developed using a microscopic Fabry-Perot interferometer with the plates implanted between the intraocula...
متن کاملQuantitative analysis of sensor for pressure waveform measurement
BACKGROUND Arterial pressure waveforms contain important diagnostic and physiological information since their contour depends on a healthy cardiovascular system 1. A sensor was placed at the measured artery and some contact pressure was used to measure the pressure waveform. However, where is the location of the sensor just about enough to detect a complete pressure waveform for the diagnosis? ...
متن کاملMachine Learning Techniques for Arterial Pressure Waveform Analysis
The Arterial Pressure Waveform (APW) can provide essential information about arterial wall integrity and arterial stiffness. Most of APW analysis frameworks individually process each hemodynamic parameter and do not evaluate inter-dependencies in the overall pulse morphology. The key contribution of this work is the use of machine learning algorithms to deal with vectorized features extracted f...
متن کاملReal-Time Analysis of Intracranial Pressure Waveform Morphology
The cranial vault is composed of four fundamental components: arterial blood, venous blood, cerebrospinal fluid (CSF), and brain parenchyma. Intracranial pressure (ICP) represents the pressure within the brain parenchyma and cerebrospinal fluid (CSF). The environment within the cranial vault is unique compared to other organ systems; it is enclosed within a rigid skull and thus small volumetric...
