Filter by:The aim of the study is to investigate the accuracy of a new semi-invasive cardiac output monitoring system in patients undergoing elective cardiac surgery. The investigators hypothesize that the semi-invasive device may be affected by mean arterial pressure and systemic vascular resistance.
Determining fluid responsiveness in critically ill patients by measuring mean systemic filling pressure on the intensive care unit.
The aim of this study is to evaluate the correlation of capnography with non-invasive measurement of cardiac output with the FloTrac/EV1000 following a reversible fluid challenge, a passive leg raising maneuver, using thermodilution as the gold standard. The main hypothesis is a correlation of 0.8 between the increasing of ETCO2 and the increasing of ejection volume measured by FloTrac/EV1000 following a passive leg raising maneuver.
The purpose of this study is to compare changes of minimally invasive arterial pulse contour cardiac output with changes of intermittent and continuous thermodilution cardiac output by pulmonary artery catheter in hemodynamic unstable patients with rapid changing vascular tone (changing dosage of vasoactive drugs or inotropics, or volume challenge). Simultaneously, global parameters of oxygen delivery and consumption will be compared with regional flow parameters and tissue oxymetry (near infrared spectrometry and laser-Doppler). While continuous thermodilution cardiac output is used for patient management, pulse contour cardiac output, intermittent thermodilution cardiac output and tissue oxymetry is only used for monitoring.
The purpose of this study is to evaluate if the continuous availability of minimally invasive cardiac output data during treatment in the intensive care unit (ICU) for hemodynamic instability, in comparison to standard of care will shorten the time needed to stabilize the patient. The researchers hypothesize that early detection of instability improves the prognosis and treatment outcome of emergency intensive care patients with hemodynamic instability.
