Obstructive Sleep Apnea and Cardiac Index

Chest, 1986
Seventeen men (age range, 21 to 58 years) with severe obstructive sleep apnea syndrome (OSAS) documented by nocturnal polysomnography underwent hemodynamic investigations during sleep. We studied the evolution of the cardiac index during apneic events in both NREM and REM sleep using the thermodilution technique.

Thermodilution and Fick cardiac index determinations following cardiac surgery

Critical Care Medicine, 1975
With 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, 1978
Ultrasound 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, 2012
Noninvasive 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 ...

A Simple Radiocardiographic Index of Cardiac Output

Radiology, 1963
The 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 Function Tests as Indexes of Fitness

Research Quarterly. American Association for Health, Physical Education and Recreation, 1969
Abstract 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 ...

Cardiac response as an index of the effect of aversion therapy

Behaviour Research and Therapy, 1984
Abstract 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).

How to Interpret Cardiac Output and Haemodynamic Indexes

2001
Essentially, 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 ...
