Techniques for cardiac output measurement, albeit of varying accuracy, invasiveness and complexity, have been available commercially for the past 25 years, although their use in the UK is relatively sparse, both in intensive and coronary care units1 and operating theatres.2 The national confidential ...
What is the cardiac output of a person with an aortic root area of 0.5 cm2, heart rate of 72 beats per minute, ejection period of 0.3 second and a pressure gradient of 45 mmHg? 5.22. The answer to the previous question somewhat underestimates the cardiac output of a person: (1) illust...
To describe early, continuous, non-invasive measures of cardiac output (CO) and evolution over time in infants with hypoxic-ischaemic encephalopathy (HIE). Prospective observational study of 44 infants with HIE (23 mild, 17 moderate, 4 severe) and 17 ter

The sympathetic release of catecholamines, along with endocrine release from the adrenal glands, regulates the heart during changing demands in cardiac output, such as in exercise. However, cardiac catecholaminergic signalling is implicated in a range of chronic and acute disease states such as heart ...
An apparatus is in development which measures the blood outflow through the heart valves by means of the bolus thermodilution method and which from then on measures the continuous cardiac output, considering the formula of Gorlin and the measurement of the blood pressure in the compartments of the...
Vascular pressures, cardiac output and a blood gas were recorded at 0, 20 and 40min. Measurements and results In infants receiving iNO first, iNO lowered the pulmonary vascular resistance index (PVRI) from 3.45 to 2.95units ( p =0.01); sildenafil further reduced PVRI to 2.45units ( p <...
The monitoring of cardiac output is a common diagnostic technique used to evaluate the heart function and fitness of a patient. Cardiac output is sometimes defined as the volume of blood pumped by the heart over a period of time and is typically expressed in units of liters per minute (L/...
