Thermodilution and Fick cardiac index determinations following cardiac surgery
Critical Care Medicine, 1975With the thermodilution technique, repeated determination of cardiac index (CI) has become a rapid, easily accomplished, safe procedure. We paired 77 CI determinations measured by direct Fick and thermodilution techniques in 21 patients who underwent myocardial revascularization.

Echocardiography as an Index of Cardiac Performance
Hospital Practice, 1978Ultrasound imaging of the heart provides a noninvasive technique for assessing cardiac performance and diagnosing a wide range of disorders. Recent improvements in two-dimensional, planar instrumentation promise to make echocardiography even more versatile, permitting more comprehensive views of left ventricular function, valve orifice areas, and the ...

Measuring cardiac index with a focused cardiac ultrasound examination in the ED
The American Journal of Emergency Medicine, 2012Noninvasive technology may assist the emergency department (ED) physician in determining the hemodynamic status in critically ill patients. The objective of our study was to show that ED physicians can accurately measure cardiac index (CI) by performing a bedside focused cardiac ultrasound examination.A convenience sample of adult subjects were ...

Cardiac Function Tests as Indexes of Fitness
Research Quarterly. American Association for Health, Physical Education and Recreation, 1969Abstract Ventricular function measurements such as the Tension Period (TP) and the Q to First Heart Sound Interval (Q-1HSI) have received increasing attention as possible simple indexes of a person's cardiovascular fitness. In order to evaluate the usefulness of these tests for measuring fitness, they were compared with fitness scores obtained using a ...

A Simple Radiocardiographic Index of Cardiac Output
Radiology, 1963The cardiac output may be determined from a radiocardiographic tracing. This method is somewhat tedious because it requires, in addition to the tracing, the determination of the total blood volume. The usual method for calculating the cardiac output from the radiocardiogram is a modification of that of MacIntyre et al.

Cardiac response as an index of the effect of aversion therapy
Behaviour Research and Therapy, 1984Abstract Recent research shows that aversion conditioning produces conditioned aversions to target stimuli. Conditioned aversions are manifest in the following posttreatment changes in S s' responses to target stimuli: increased negative evaluations, decreased contact or consumption, and increased phasic heart-rate responses (HRRs).

Computer-Automated Impedance-Derived Cardiac Indexes
IEEE Transactions on Biomedical Engineering, 1986In this study, an automated signal processing technique, ensemble averaging, provided artifact-free impedance data which permitted analysis during quiet breathing and exercise in normal young male subjects. Moreover, impedance-derived stroke volumes and other cardiac indexes calculated by ensemble-averaging showed close correlation with those ...

How to Interpret Cardiac Output and Haemodynamic Indexes
2001Essentially, the goal of all haemodynamic monitoring and measurement in the critically ill patient is to ensure that adequate organ blood flow and oxygenation are maintained and to enable appropriate treatments to be instituted as necessary to avoid the potential complications of regional hypoxia, including the development of organ dysfunction and ...
