Cardiac Output Assessed by Invasive and Minimally Invasive Techniques
Cardiac output (CO) measurement has long been considered essential to the assessment and guidance of therapeutic decisions in critically ill patients and for patients undergoing certain high-risk surgeries. Despite controversies, complications and inherent errors in measurement, pulmonary artery catheter (PAC) continuous and intermittent bolus techniques of CO measurement continue to be the gol...
متن کاملMeasuring cardiac output: intermittent bolus thermodilution method.
cialist in the cardiac care unit and cardiac observation unit at UCLA Medical Center and is an assistant professor of nursing at the UCLA School of Nursing, Los Angeles, Calif. by a computer and converted into a measurement of cardiac output. Cardiac output is inversely proportional to the area under the curve. The normal cardiac output curve has a rapid smooth upstroke and a gradual downstroke...
متن کاملApplications of minimally invasive cardiac output monitors
Because of the increasing age of the population, critical care and emergency medicine physicians have seen an increased number of critically ill patients over the last decade. Moreover, the trend of hospital closures in the United States t imposes a burden of increased efficiency. Hence, the identification of devices that facilitate accurate but rapid assessments of hemodynamic parameters witho...
متن کاملLess invasive indicators of changes in thermodilution cardiac output by ventilatory changes after cardiac surgery.
BACKGROUND AND OBJECTIVE We studied whether changes in less invasive, noncalibrated pulse-contour cardiac output (by modified ModelFlow, COmf) and derived stroke volume variations (SVV), as well as systolic and pulse pressure variations, predict changes in bolus thermodilution cardiac output (COtd), evoked by continuous and cyclic increases in intrathoracic pressure by increases in positive end...
متن کاملMinimally invasive cardiac output monitoring in the perioperative setting.
With advancing age and increased co-morbidities in patients, the need for monitoring devices during the perioperative period that allow clinicians to track physiologic variables, such as cardiac output (CO), fluid responsiveness and tissue perfusion, is increasing. Until recently, the only tool available to anesthesiologists to monitor CO was either a pulmonary artery catheter or transesophagea...
