BACKGROUND: Cardiac output is an important hemodynamic variable and determines oxygen delivery. In contrast to blood pressure, cardiac output is rarely measured even in high-risk surgical patients, suggesting that clinicians consider blood pressure to be

An evaluation of the cardiac index
American Heart Journal, 1966Abstract The value of using the body surface area to correct cardiac output for body size (cardiac index) has been studied in several ways. Its historical development has been traced and an attempt made to point out the strengths and weaknesses of the early data.

Cardiac Index Changes With Fluid Bolus Therapy in Children With Sepsis—An Observational Study*
Pediatric Critical Care Medicine, 2018Objectives: Fluid bolus therapy is the initial recommended treatment for acute circulatory failure in sepsis, yet it is unknown whether this has the intended effect of increasing cardiac index.

Assessment of Cardiac Index in Anemic Patients
Chest, 2000During isovolemic hemodilution, healthy individuals maintain oxygen consumption VO2 by identical increases in cardiac index (CI) and oxygen extraction ratio (O(2)ER). In critically ill patients, the relationship between CI and O(2)ER may be different. Patients with an altered cardiac function may have a decreased CI/O(2)ER ratio, whereas patients with ...

General index for the assessment of cardiac function
The American Journal of Cardiology, 1972Abstract The concept of a “normalized velocity” was employed to provide a uniform approach for the assessment of cardiac function. In particular, the quantities [(dp/dt/)/p]max, [(dV/dt/)/V]max and [t(dl/dt/)/l]max were applied to data taken from 89 studies in 71 infants, children and young adult patients.

The effect of obesity on bioimpedance cardiac index
The American Journal of Surgery, 2005Cardiac performance may be assessed noninvasively at the patient's bedside by using thoracic bioimpedance. However, it is unclear if this technique can be used reliably in critically injured obese patients because of increased body habitus and chest wall mass.A prospectively maintained database was used to identify all trauma patients admitted to the ...

Obstructive Sleep Apnea and Cardiac Index
Chest, 1986Seventeen 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.

Use of cardiac index in pregnancy: Is it justified?
American Journal of Obstetrics and Gynecology, 1995The aim of this study was to test the hypothesis that standardization of cardiac output in pregnancy by correcting for body surface area, and thus obtaining cardiac index, is justified.Cardiac output was determined by thoracic electrical bioimpedance monitoring in 78 pregnant women; recordings were made at 1-month intervals from the first antenatal ...
