Neural reflex regulation of arterial pressure in pathophysiological conditions : interplay among the baroreflex, the cardiopulmonary reflexes and the chemoreflex
(1997-04)
The maintenance of arterial pressure at levels adequate to perfuse the tissues is a basic requirement for the constancy of the internal environment and survival. The objective of the present review was to provide information ...
Echocardiographic Doppler estimation of pulmonary artery pressure in critically ill patients with severe hypoxemia
(2008-01-01)
BACKGROUND: In spontaneously breathing cardiac patients, pulmonary artery pressure (PAP) can be accurately estimated from the transthoracic Doppler study of pulmonary artery and tricuspid regurgitation blood flows. In ...

Estudo comparativo da pressão arterial sistêmica obtida por dois métodos distintos
(2006-12-01)
As arterial hypertension can be diagnosed by different methods, among which are the traditional auscultatory instrument and the automated oscillometric monitor, the aim of this study was to compare the performance of these ...
A model of internal control may improve the response time of an automatic arterial pressure controller
(IEEE, 2000)
A simplified model for the arterial pressure control system was implemented on a personal computer using Matlab Simulink(R). Model responses to variations of systemic vascular resistance were comparable to those predicted ...
Estudo comparativo dos efeitos hemodinâmicos e ventilatórios da ventilação controlada a volume ou a pressão, em cães submetidos ao pneumoperitônio
(2005-11-01)
BACKGROUND AND OBJECTIVES: Pressure controlled ventilation (PCV) is available in anesthesia machines, but there are no studies on its use during CO 2 pneumoperitoneum (CPP). This study aimed at evaluating pressure-controlled ...

Role of brain nitric oxide in the cardiovascular control of bullfrogs
(2013-06-01)
The goal of the present study was to determine if nitric oxide (NO) acting on the brain of bullfrog (Lithobates catesbeianus) is involved in arterial pressure and heart rate (HR) control by influencing sympathetic activity. ...
