Acute Hemodynamic Responses to Weightlessness in Humans

The Journal of Clinical Pharmacology, 1989
As NASA designs space flights requiring prolonged periods of weightlessness for a broader segment of the population, it will be important to know the acute and sustained effects of weightlessness on the cardiovascular system since this information will contribute to understanding of the clinical pharmacology of drugs administered in space.

Hemodynamic responses during prolonged sitting

Journal of Applied Physiology, 1983
Eight young men (group A) underwent 5 h of quiet sitting, preceded by 30 min of recumbency, 20 min of standing, and 20 s of walking, and five other young men (group B) underwent 70 min of sitting, preceded by recumbency only, to determine the effects of prolonged sitting and previous posture on hemodynamic responses (measured by impedance ...

Hemodynamic responses to glycols and to hemolysis

Canadian Journal of Physiology and Pharmacology, 1969
Ethylene and propylene glycol both decrease renal blood flow in dogs while increasing flow through the superior mesenteric artery. The decrease in renal blood flow is not a passive response to dilatation of major vascular beds since it precedes the increment in superior mesenteric arterial flow and since it can be duplicated by direct injection of ...

Peritonitis: Failure of hemodynamic response with dopamine

Journal of Pediatric Surgery, 1983
Despite a 50% mortality rate in infants with peritonitis and sepsis, little is known regarding the hemodynamic changes in these patients or their response to inotropic agents. This study evaluates these factors in a neonatal pig model with peritonitis and sepsis.

Carbohydrate metabolism and the hemodynamic response to shock

Journal of Surgical Research, 1985
To investigate the temporal relationship of changes in carbohydrate metabolism to changes in the hemodynamic stability of the dog in protracted hemorrhagic shock, 30 animals were studied. Blood pressure was maintained at 60 mm Hg for 12 hr during which hemodynamic and metabolic parameters were studied.

Acute hemodynamic response and uremic toxin removal in conventional and extended hemodialysis and hemodiafiltration: a randomized crossover study.

American Journal of Kidney Diseases, 2014
BACKGROUND Intensive hemodialysis (HD) may have significant benefits. Recently, the role of extended hemodiafiltration (HDF) has gained interest. The aim of this study was to evaluate the acute effects of extended HD and HDF on hemodynamic response and ...

Postprandial hemodynamic responses in patients with cirrhosis

Hepatology, 1988
The hemodynamic response to a 800 kcal liquid meal was investigated in 24 patients (study group) with cirrhosis and two control groups. One control group of six cirrhotic patients (volume control) had a calorie-free equivolumic electrolyte solution.

The Hemodynamic Response to Enteral Nutrition

1999
In modern intensive care, enteral nutrition is the route recommended to provide artificial nutrition. The advantages of enteral nutrition are numerous, although not definitely proven [1]. The most important claimed advantages include: Maintenance of the gut mucosal barrier function, with concomitant reduction of endotoxin and bacteria translocation [2];

Hemodynamic responses to photic stimulation in neonates

Pediatric Neurology, 2000
A three-channel near-infrared monitoring system was used to evaluate the regional hemodynamic responses to photic stimulation during spontaneous sleep in seven healthy neonates. Three pairs of parallel light guides, separated by 15 mm each, were placed over a 450-mm(2) occipital region of the head.

The BOLD Hemodynamic Response in Healthy Aging

Journal of Cognitive Neuroscience, 2004
Abstract Several previous studies have compared the blood oxygen level-dependent (BOLD) hemodynamic response (HDR) in healthy elderly subjects to the HDR in young subjects. Some studies have found a relative decreased amplitude in the elderly in the visual cortex, whereas other studies have found the elderly HDR amplitude in the visual ...
