Intracranial blood-flow velocity and pressure measurements using an intra-arterial dual-sensor guidewire.
Hemodynamics is thought to play a role in the growth and rupture of intracranial aneurysms. In 4 patients, we obtained local pressure and BFV by using a dual-sensor pressure and Doppler velocity wire within and in vessels surrounding unruptured aneurysms. Local BFVs can serve as boundary conditions for computational fluid dynamics, whereas pressure recordings provide direct information on the m...
متن کاملLevel of agreement between Nexfin non-invasive arterial pressure with invasive arterial pressure measurements in children.
BACKGROUND We compared Nexfin non-invasive arterial pressure measurements using a novel small finger cuff with intra-arterial pressure in the paediatric setting in order to establish the level of agreement between both methods. METHODS The study included 41 children aged 2-16 yr admitted for surgery or paediatric intensive care with an intra-arterial catheter as part of standard monitoring. V...
متن کاملIntra-arterial Pressure Measurement with Strain Gauge and Amplifier *
The purpose of this paper is briefly to describe intra-arterial pressure recording by means of a strain gauge pressure transducert and amplifiers. The use of resistance wire strain gauges for blood pressure recording with galvanometers has already been described.1"8 The use of the strain gauge with electronic amplification as a plethysmograph has also been described.2 Since alternating input cu...
متن کاملIntra-aneurysmal pressure measurements in experimental saccular aneurysms in dogs.
Intra-aneurysmal pressure was studied in an experimental model of saccular aneurysm in dogs, using a vein pouch grafted onto a common carotid arterial bifurcation. The mean and the pulse pressures were recorded simultaneously from within the aneurysm and within the common carotid artery, before and after 50% proximal carotid artery stenosis. These experiments were performed under systemic normo...
متن کاملMonitoring Personalized Trait Using Oscillometric Arterial Blood Pressure Measurements
The blood pressure patterns obtained from a linearly or stepwise deflating cuff exhibit personalized traits, such as fairly uniform peak patterns and regular beat geometry; it can support the diagnosis and monitoring of hypertensive patients with reduced sensitivity to fluctuations in Blood Pressure BP over time. Monitoring of personalized trait in Oscillometric Arterial Blood Pressure Measurem...
