In sodium pentobarbital-anesthetized dogs with spontaneous nasal blood flow or constant-flow vascular perfusion of the nasal mucosa, we measured nasal airway resistance, vascular resistance, and arterial inflow and outflow of the anterior and posterior venous systems. Acetylcholine in low doses (<5 μg/kg per minute, intraarterially) increased nasal airway resistance, and the response was greater in dogs with spontaneous blood flow. Nasal vascular resistance was decreased. However, the posterior venous outflow was increased and the anterior venous outflow was decreased in dogs with constant-

Whether laser-Doppler flowmetry can be used to monitor liver blood flow was evaluated in a porcine model in which portal venous blood flow was followed indirectly by electromagnetic flowmetry applied to the superior mesenteric artery, and total hepatic venous outflow was measured directly by using an extracorporeal circuit. Hepatic venous outflow at rest was 23.5 +/- 5.7 ml.kg body wt-1.min-1. Occlusion of the hepatic arterial supply reduced hepatic laser-Doppler blood flow to 22%, but hepatic venous outflow only to 80%. Portal venous blood flow remained unchanged or increased slightly.

Object In the majority of adults with idiopathic intracranial hypertension (IIH), there is an elevation in venous pressure associated with a venous outflow stenosis. In about 15% of IIH patients the elevated venous pressure is associated with an elevation in blood flow but little or no evidence of a stenosis. Venostenotic IIH and idiopathic hydrocephalus in children with a normal blood inflow have been shown to be equivalent. The aim of this study was to test whether children with hydrocephalus and an elevated arterial inflow have a vascular pathophysiology that is analogous to the hyperemic f

The Phoenix left ventricular assist device is driven by pneumatic pump outside a human body to provide air flow in-and-out of a pneumatic diaphragm inside the blood chamber. The inflation and deflation of the diaphragm drives the blood flows. At peak systole, blood flows into aorta with a maximum flow rate both from natural ventricle and artificial ventricle. To assess the critical condition, blood flow pattern of the device at peak systole is studied. We apply the finite volume method with ϰ – ε turbulent model to simulate the steady flow at peak systole. Results provide a comprehension of fl

Abstract:
Vascular steal refers to the diversion of blood flow between collateral vessels that share a common inflow restricted by arterial stenosis. Blood is diverted from the high-pressure to the low-pressure, low-resistance system. Vascular steal is associated with anatomical bypass or vasodilation in the collateral network and is called “the arterial steal”. However, we have demonstrated that in the presence of an outflow gradient (e.g., intra-extracranial), blood is shunted to a lower pressure system, a phenomenon we term “venous steal”.

In the perioperative period, various mechanisms can lead to the development of shock. The type of shock needs to be rapidly elucidated and initial management steps initiated to minimize the time of tissue hypoperfusion. Obstructive shock is caused by physical obstruction of circulation either into or out of the heart. The mechanisms that lead to obstructive shock either prevent blood from entering the right heart during diastole such as a tension pneumothorax or pericardial tamponade, or prevent the heart from ejecting the blood due to a physical obstruction, as in the case of pulmonary emboli

Abstract:
Compartment syndrome is a painful condition, caused by increased pressure in a closed muscular compartment. A compartment is a group of muscles enclosed in fascia and septa of connective tissue, which separates different muscle groups. The chambers created receive their blood supply through the arteries. As the pressure builds in the closed space, the blood supply to muscles enclosed decreases. Normal compartment pressure allows blood to flow in and then venous outflow to exit the compartment. However, with increased pressure in the compartment, the arterial flow is impaired. Subsequently, ven

Abstract The sympathetic vasomotor outflow is composed of a series of parallel and differentially regulated efferent pathways that control the cardiac output and the vascular tone of somatic and visceral structures. These pathways are thought to be organized in a highly specific fashion. For example, it is currently believed that specific sets of sympathetic preganglionic neurons may regulate the activity of muscle vasoconstrictor sympathetic postganglionic fibers and other sympathetic preganglionic neurons may control cutaneous vasoconstrictor postganglionic neurons (see Chapter 18).

Abstract:
Abstract Pulse-synchronous tinnitus (PST) has been linked to multiple anatomical variants of the venous outflow tract, including transverse sinus (TS) stenosis and sigmoid sinus (SS) dehiscence. It is unknown if the size of diameter in the TS part at the symptomatic side will result in PST. In this study, a combined experimental and computational approach is adopted to study the blood flow during PST. A parametric study is performed on the diameter size of one PST patient at the symptomatic side. A Reynold-averaged-Navier-Stokes (RANS) flow solver is employed in ANSYS Fluent to simulate the sy
