Commissural NTS lesions and cardiovascular responses in aortic baroreceptor-denervated rats
(1999-10-01)
Both acute (1 day) lesions of the commissural nucleus of the solitary tract (commNTS) and aortic baroreceptor denervation increase pressor responses to bilateral common carotid occlusion (BCO) during a 60-second period in ...
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. ...
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 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 ...

(Wiley-Blackwell, 2012-07-01)
Objective To evaluate the agreement between invasive blood pressure (IBP) and Doppler ultrasound blood pressure (DUBP) using three cuff positions and oscillometric blood pressure (OBP) in anesthetized dogs.Study design ...
LESION OF THE ANTEROVENTRAL 3RD VENTRICLE REGION IMPAIRS THE RECOVERY OF ARTERIAL-PRESSURE INDUCED BY HYPERTONIC SALINE IN RATS SUBMITTED TO HEMORRHAGIC-SHOCK
(Elsevier B.V., 1992-07-31)
The effect of intravenous infusion of hypertonic saline (HS, 7.5% NaCl) on the recovery of mean arteria pressure (MAP) after hemorrhage was studied in sham-operated rats and in rats with electrolytic lesion of the anteroventral ...
Effect of passive pneumoperitoneum on oesophageal pressure, cardiovascular parameters and blood gas analysis in horses
(Wiley-Blackwell, 2011-07-01)
P>Reasons for performing study:Standing surgical procedures are being employed to an ever-greater extent in horses. Pneumoperitoneum during abdominal surgery might adversely affect the work of breathing.Objectives:To ...
