Filter by:Primary: To observe how hemodynamic parameters are affected by age during rest and exercise in healthy humans. Furthermore, how an acute fluid challenge changes hemodynamic parameters. Secondary: To thoroughly examine this population with regard to cardiac performance and function, anthropometrics, metabolic status, exercise capability, constitution, pulmonary status, and humoral markers of organ functions. This population will serve as a healthy control group, to which different populations can be compared, hence the need for a comprehensive characterization. Hypotheses: Diastolic function and parameters associated with diastolic function gradually deteriorate with increasing age. The gradual deterioration is unmasked at an earlier age during exercise and fluid challenge, compared to measurements made at rest.
This study is being done to look at the cardiovascular response, if any, to intake of commercially available energy drink. We hypothesize that energy drink consumption compared to a control drink in healthy adults alters the cardiovascular hemodynamic system.The focus of this study is to elucidate the physiological/cardiovascular response to an energy drink consumption as compared to a control drink both at rest and during stressful conditions in healthy adults.
Our hypothesis is that hemodynamic fluid resuscitation guided by dynamic parameters will improve outcome in patients with severe sepsis and septic shock, by limiting the deleterious effects of fluid overload.
In this trial, the investigators intend to examine whether the concentration of local anesthetics during epidural analgesia could be modulating factor for change of hemodynamics in patients undergoing major upper abdominal surgery.
The ideal mean arterial pressure in patients with septic shock is unknown. The expert's recommandations have stated a target between 65 and 70 mm Hg. However the scientific basis are weak. Indead there are only few prospective studies which addressed this question without clear answer. Therefore we designed a RCT in order to assess the effect on mortality of two levels of mean arterial pressure in patients with septic shock.(800 patients, 30 centres)
The purpose of this study is to compare CVP measurements from CICCs and PICCs. The investigators will also evaluate whether or not the duration of CICC placement affects the differences in CVP measurements between the CICCs and PICCs. The investigators hypothesize that the differences between the CVP measurements of the CICCs and PICCs will be clinically insignificant.
Twenty adult volunteers will be administered Pico-Salax in the usual fashion for colonoscopy with intense monitoring of serum and urine chemistry and hemodynamics.
This is a prospective, observational study to compare presep(tm) catheter central vein mixed venous oxygen saturation before and after dialysis is initiated via the vascath(tm) central venous dialysis catheter to evaluate device interaction.
The purpose of this study is to determine whether polymorphisms in G protein subunits, namely Galphas and Galphaq, are associated with altered cardiac performance in heart failure patients.
Fluid and volume management are a challenging part of critical care and the difficulties increase in the face of renal failure. Utilizing the Crit-Line to monitor blood volume changes in conjunction with arterial pressure cardiac output monitoring may lead to better understanding of the impact fluid removal during dialysis has on hemodynamics.
