BACKGROUND For complex patients in the intensive care unit or in the operating room, many questions regarding their haemodynamic management cannot be answered with simple clinical examination. In particular, arterial pressure allows only a rough estimation of cardiac output. Transpulmonary thermodilution is a technique that provides a full haemodynamic assessment through cardiac output and othe...
One of the most important economic factors is potential output. In macroeconomic models and structural studies, the estimation of potential output is necessary for projections and analyzing policy performances. There exist several methods for estimating potential output. Meanwhile, its estimation is a difficult and complicated matter. Empirical studies and researches show that using various te...
rivers and runoff have always been of interest to human beings. in order to make use of the proper water resources, human societies, industrial and agricultural centers, etc. have usually been established near rivers. as the time goes on, these societies developed, and therefore water resources were extracted more and more. consequently, conditions of water quality of the rivers experienced rap...
Background: Cardiac output (CO) is the total volume of blood pumped by the heart per minute and is a function of heart rate and stroke volume. CO is one of the most important parameters for monitoring cardiac function, estimating global oxygen delivery and understanding the causes of high blood pressure. Hence, measuring CO has always been a matter of interest to researchers and clinicians. Sev...
Cardiac output (CO) is a cardinal parameter of cardiovascular state, and a fundamental determinant of global oxygen delivery. Historically, routine clinical measurement of CO has been limited to critically-ill patients, often with invasive indicator dilution methods such as thermodilution. A variety of cardiac output estimators have been developed over the past hundred years. The estimator eval...
OBJECTIVES This study assessed the prognostic value of peak cardiac power output, measured non-invasively during maximal cardiopulmonary exercise testing, against other exercise-derived haemodynamic variables in patients with chronic congestive heart failure. METHOD AND RESULTS Two hundred and nineteen unselected, consecutive patients with congestive heart failure (166 men, mean (+/-SD) age o...
