In a preferred embodiment, a pulsatile flow of fluid is achieved by cyclically alternating the velocity of the piston between two different speeds. A desired average flow rate and/or delivery pressure and/or constant pulse pressure is maintained by adjusting the alternating velocities at …Author: Kenneth A.

Pulsatile Drug Delivery Systems: 1-3 A Pulsatile drug delivery system delivers drug in rapid and burst manner within a short time period immediately after a programmable lag phase. There are many situations where drug is needed to be released immediately (after bursting the delaying film coat) at specific site. These situations,

Pulsatile systems are gaining a lot of interest as they deliver the drug at the right site of action at the right time and in the right amount, thus providing spatial and temporal delivery and increasing patient compliance. These systems are designed accor ding to the cir cadian rhythm of the body .Author: Shweta Arora, J Ali, Alka Ahuja, Sanjula Baboota, J Qureshi

Syringomyelia is a disease that arises from a primary disorder outside the spinal cord and obstructs the normal pulsatile flow of cerebrospinal fluid. Because the mechanism of the origin and progression of the syrinx is outside the spinal cord, surgical intervention that can relieve the obstruction to CSF flow is preferred to surgical methods that require invasion of the spinal cord to shunt syrinx fluid.

Pulsatile flow provides better preservation of renal function and systemic vascular tone . In a separate study using a ventricular fibrillation model, the i-cor system with pulsatile flow was able to restore and significantly increase coronary artery flow in adult swine compared to the conventional nonpulsatile perfusion system .Author: Eric L.

Mar 08, 2014 · Pulsatile tinnitus is also called "vascular tinnitus", and it usually has something to do with the vascular system. Also, you may still be retaining some fluid and may have fluid in your ear. It is possible that, with time, the fluid will drain and your PT will subside.

Jan 19, 2017 · A 24-year-old, ASA II, G1P0 full-term parturient presented to the Labor and Delivery for vaginal delivery. Her past medical history was significant for gestational diabetes and ACM-1. A diagnosis of ACM-1 was made 12 years ago when a brain MRI was performed for right-sided numbness developing following a motor vehicle collision.Author: Ramsis F.

In this article, dynamics of the cerebrospinal fluid (CSF) was studied, using computational fluid dynamics. Using MRI images of two special cases, a 2-dimensional model of the ventricular system was made. CSF velocity and pressure distribution in ventricular system have high importance since the flow pattern of this liquid has an important effect on intracranial pressure, i.e., ICP, which has ...Author: N Masoumi, D Bastani, S Najarian, F Farmanzad, A M Seddighi
https://en.wikipedia.org/wiki/Pulsatile_flow
In fluid dynamics, a flow with periodic variations is known as pulsatile flow, or as Womersley flow.The flow profiles was first derived by John R. Womersley (1907–1958) in his work with blood flow in arteries. The cardiovascular system of chordate animals is a very good example where pulsatile flow is found, but pulsatile flow is also observed in engines and hydraulic systems, as a result of ...
