Hemodynamic responses during prolonged sitting
Journal of Applied Physiology, 1983Eight 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 instability and fluid responsiveness
Canadian Journal of Anesthesia/Journal canadien d'anesthésie, 2013The rapid response team was called to evaluate a 64-yr-old hypotensive and hypoxic female patient hospitalized for deep venous thrombosis. Low-molecular-weight heparin had been initiated two days previously. The rapid response team observed her vital signs: heart rate, 110 beats min; blood pressure, 90/65 mmHg; and oxygen saturation, 90% while ...

Splanchnic Hemodynamic Responses to Glucagon
Archives of Surgery, 1970Glucagon, a substance originally thought exclusively to play a part in carbohydrate metabolism, has during recent years been found to possess several other important properties. Among them are influence on tubular reabsorption of electrolytes, 1 on adrenal medullary secretion, 2 on calcium metabolism, 3 on gastric secretion, 4 and on gastrointestinal ...

Hemodynamic Response to the Upright Posture
The Journal of Clinical Pharmacology, 1994The authors' objective was to review previous studies of immediate (first 30 seconds) and stabilized (30 seconds to 20 minutes) hemodynamic responses of healthy adults to the head‐up posture, with particular reference to alteration of such responses in the elderly and the usefulness of such data in the diagnosis of orthostatic hypotension.

Hemodynamic Responses to Sarafotoxin 6 Peptides
Journal of Cardiovascular Pharmacology, 1991Hemodynamic responses to sarafotoxin (SFTX6) peptides and endothelin-1 (ET-1) were compared in the anesthetized cat. SFTX6a and ET-1 at a dose of 0.3 nmol/kg i.v. produced a biphasic change in arterial pressure characterized by an initial decrease followed by a secondary increase in pressure.

Normal Hemodynamic Response to Exercise
Heart Failure ClinicsExercise pulmonary hypertension has been invasively defined as mean pulmonary artery pressure/cardiac output slope greater than 3 mm Hg/L/min. Recent advances suggest the sustainable role of exercise Doppler echocardiography for the study of the right heart and pulmonary circulation unit (RH-PCU).

Hemodynamic responses to BNP in rats
European Journal of Pharmacology, 1989Le peptide natriuretique cerebral (BNP) a ete recemment isole et c'est pour explorer plus profondement son activite que cette etude a ete entreprise. Elle consiste en l'etude comparee des activites sur l'hemodynamique de rats de BNP et ANP (peptide natriuretique atrial).

Modelling hemodynamic response function in epilepsy
Clinical Neurophysiology, 2013Electroencephalography and functional magnetic resonance imaging (fMRI) can be combined to noninvasively map abnormal brain activation elicited by epileptic processes. A major aim was to investigate the impact of a subject-specific hemodynamic response function (HRF) to describe the differences across patients versus the use of a standard model.We ...

Hemodynamic response to graded water immersion
Klinische Wochenschrift, 1981Hemodynamic response to graded immersion was studied in healthy male subjects in a thermoneutral bath in the sitting position. Pressures in the right heart and cardiac output were determined by means of a semifloating catheter with a thermistor probe.
