Blood pressure and hemodynamic responses to an acute sodium load in humans.
The purpose of this study was to investigate the acute blood pressure (BP) and hemodynamic effects of sodium chloride (3% intravenous solution). Although many studies link a change in dietary sodium to a change in BP, few consider the effects of sodium concentration in the blood on BP. We hypothesized that an intravenous sodium load would increase BP, and we quantified alterations in cardiac ou...
متن کاملAcute Hemodynamic Effects of Dopamine
The hemodynamic effects of dopamine were studied in 62 patients with clinical shock. In 36 patients with infection dopamine increased mean arterial pressure (MAP) 30%, and cardiac output (CO) 37%. Urine flow (UF) increased from 0.5 ml/min to 1.6 ml/min. Norepinephrine (NE) in 26 patients resulted in a higher MAP, lower CO, and similar UF. Isoproterenol (Isp) in 19 patients resulted in a lower M...
متن کاملDirect effect of increased hemodynamic load on cardiac mass.
The hearts of rats were transplanted into the abdomens of recipients of the same inbred strain by attaching the stumps of aorta and pulmonary artery end to side to the abdominal aorta and inferior vena cava, respectively, of the recipient. The transplant functions as a denervated "nonworking" Langendorff heart; the recipient in situ heart serves as a normal control. One week after surgery, an o...
متن کاملA Liquid-Solid Coupling Hemodynamic Model with Microcirculation Load
From the aspect of human circulation system structure, a complete hemodynamic model requires consideration of the influence of microcirculation load effect. This paper selected the seepage in porous media as the simulant of microcirculation load. On the basis of a bi-directional liquid-solid coupling tube model, we built a liquid-solid-porous media seepage coupling model. The simulation paramet...
متن کاملHemodynamic compensation during acute normovolemic hemodilution.
To the Editor:—Acute normovolemic hemodilution (ANH) causes a reduction in arterial oxygen content because of reduced hemoglobin concentration. The primary compensatory mechanism during ANH is an increase in cardiac output to maintain systemic oxygen delivery. Therefore, the lower limit of an acceptable hemoglobin concentration is related to how low hemoglobin can be reduced without jeopardizin...
