15. Determination of cardiac output by an angle and diameter independent dual beam Doppler technique in critically ill infants.
OBJECTIVE--To compare cardiac output measurements in critically ill infants by the dual beam Doppler and thermodilution techniques. DESIGN--Prospective direct comparison of the two techniques. For statistical evaluation one randomly assigned paired measurement of every patient was used. SETTING--Paediatric intensive care unit in a university hospital. PATIEN

16. Transoesophageal Doppler echocardiographic measurement of cardiac output by the mitral annulus method
Objective—To compare cardiac output measured by the transoesophageal Doppler and thermodilution techniques.

17. Coronary sinus blood flow and coronary haemodynamic function in children: measurement by the continuous thermodilution method with coronary sinus cannulation via the femoral vein.
In 19 children with Kawasaki disease without any cardiac sequelae the coronary sinus was cannulated via the femoral vein with a specially designed flow catheter and coronary sinus blood flow was measured by the continuous thermodilution method. There was a statistically significant positive correlation between coronary sinus blood flow and age, body surface

18. A preliminary investigation on the use of thermodilution and echocardiography as an assessment of cardiac function in the cat.
A technique for the determination of cardiac output in the cat by the thermal dilution method is described. The values of cardiac output assessed by thermal dilution and the values of left ventricular function assessed echocardiographically are compared. Values of cardiac output obtained by thermal dilution compare favourably with values obtained by other in

19. Method of assessing the reproducibility of blood flow measurement: factors influencing the performance of thermodilution cardiac output computers.
Measurements of blood flow by three different makes of thermodilution cardiac output computer in an artificial circulation were analysed by linear regression against absolute flow measured by timed blood volume collection. For each computer the horizontal distance between the 95% confidence limits for a single prediction was calculated at a standard flow rat

20. Non-invasive measurement of cardiac output by a single breath constant expiratory technique.
A new single breath test has been developed that measures pulmonary blood flow (Qc) and pulmonary tissue volume by using the fact that Qc is proportional to the relationship between the absorption rate of acetylene (C2H2) from the alveolar gas and the rate of change of lung volume during constant expiratory flow. To make these measurements a bag in bottle sy

21. Equipment review: New techniques for cardiac output measurement – oesophageal Doppler, Fick principle using carbon dioxide, and pulse contour analysis
Measuring cardiac output is of paramount importance in the management of critically ill patients in the intensive care unit and of 'high risk' surgical patients in the operating room. Alternatives to thermodilution are now available and are gaining acceptance among practitioners who have been trained almost exclusively in the use of the pulmonary artery cath

22. Measurement of extravascular lung water using the single indicator method in patients: research and potential clinical value
Extravascular lung water includes all of the fluid within the lung but outside of the vasculature. Lung water increases as a result of increased hydrostatic vascular pressure or from an increase in lung endothelial and epithelial permeability or both. Experimentally, extravascular lung water has been measured gravimetrically. Clinically, the chest radiograph

23. Determination of cardiac output by Doppler echocardiography.
Cardiac output determined by Doppler echocardiography was compared with that determined by thermodilution at rest and during dobutamine infusion in 10 patients (group A) and by the Fick method at rest in 11 patients (group B). All patients had angina pectoris without valvular heart disease. Maximum spatial blood velocity and cross sectional aortic area were

24. Effects of selective and non-selective beta-adrenergic blockade on coronary dynamics in man assessed by rapid atrial pacing.
The effects on coronary dynamics of propranolol and atenolol were studied in 12 patients undergoing cardiac catheterisation for suspected coronary artery disease. Myocardial blood flow was measured using the coronary sinus continuous thermodilution technique. Data were obtained immediately after drug administration and during rapid atrial pacing. The immedia
