Prediction of post-cardiopulmonary bypass cardiac output by venous oximetry.
The present study evaluates two equations for predicting the post-cardiopulmonary bypass cardiac output (CO) in 10 patients undergoing coronary artery bypass grafting. One equation is based on the relationship of CO with mixed venous oxygen saturation (SVO 2), while the second equation is based on the relationship with oxygen extraction (1 - SVO 2). Each patient served as his own control. Du...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Relating Noninvasive Cardiac Output and Total Peripheral Resistance Estimates to Physical Activity in an Ambulatory Setting
The prevalence and cost of heart disease indicate the need for better methods of detecting, diagnosing and treating this pervasive problem. Appropriate monitoring outside of the hospital can potentially lead to earlier diagnosis and reduced costs. We use electrocardiogram (ECG) and continuous arterial blood pressure (ABP) data collected in an ambulatory setting to examine two important cardiova...
متن کاملPrediction of fluid responsiveness using a non-invasive cardiac output monitor in children undergoing cardiac surgery.
BACKGROUND This study evaluated the ability of a non-invasive cardiac output monitoring device (NICOM) to predict fluid responsiveness in paediatric patients undergoing cardiac surgery. METHODS Children aged <5 yr undergoing congenital heart surgery were included. Once the sternum had been closed after repair of the congenital heart defect, 10 ml kg(-1) colloid solution was administered for v...
متن کاملVein of Galen Aneurysmal Malformation and High-output Cardiac Failure in a Newborn
Background: Vein of Galen aneurysm (VGA) is the most common form of symptomatic cerebrovascular malformation in neonates. It develops in a fetus in the first trimester of pregnancy due to unknown reasons, but it is likely to have a genetic etiology. The prognosis of VGA is usually poor, particularly in newborns with heart failure due to high-flow intracerebral shunt. Surgery and endovascular em...
