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 ...
Mean arterial blood pressure: Potential predictive tool for preeclampsia in a cohort of healthy nulliparous pregnant women
(2019-12-03)
Background: Prediction of preeclampsia is a challenge to overcome. The vast majority of prospective studies in large general obstetric populations have failed in the purpose of obtain a useful and effective model of ...
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 ...
Effects of mercury on the arterial blood pressure of anesthetized rats
(1999-08)
The available data suggests that hypotension caused by Hg2+ administration may be produced by a reduction of cardiac contractility or by cholinergic mechanisms. The hemodynamic effects of an intravenous injection of HgCl2 ...
Effects of tiletamine/zolazepam-romifidine-atropine in ocelots (Leopardus pardalis)
(2004-07-01)
Objectives: To evaluate the effects of a combination of tiletamine-zolazepam-romifidine-atropine in ocelots. Design: Prospective experimental trial. Animals: Eight captive adult ocelots (three females and five males). ...
Pressão arterial e reatividade vascular em frangos de corte machos de cinco linhagens comerciais
(1998-01-01)
Blood pressure and vascular reactivity to phenylephrine (hypertensor) and sodium nitroprusside (hypotensor) was determined on male broilers taken from 5 commercial strains (Arbor Acres, Cobb, Hubbard-Peterson, ISA and ...
