Whole Body – Single Frequency Bioimpedance
2005The postdialysis target weight is determined as the lowest weight a patient can tolerate without intradialytic symptoms or hypotension. Patterns of electrical properties of tissues allow a direct monitoring of fluid status without the need of the body weight.Whole body impedance is measured from skin electrodes on hand and foot. Impedance (Z vector) is

Bioimpedance Measurement of Extracellular Water
Journal of Applied Physiology, 1999To the Editor : The paper by Matthie and others ([1][1]) purports to demonstrate the superiority of the Xitron multifrequency bioimpedance analyzer over single-frequency bioimpedance for measurement of extracellular water (ECW).

Bioimpedance or anthropometry?
European journal of clinical nutrition, 1989The ability of bioimpedance (BIA) to predict body composition in comparison with anthropometric measurements (weight and height) was assessed on three groups of adult young women (n = 99) and one group of adult young men (n = 49). Body fat (BF) and fat-free mass (FFM) by densitometry were used as the reference data.

Bioimpedance in the Pacemaker Clinic
AACN Clinical Issues: Advanced Practice in Acute and Critical Care, 1999Thoracic electrical bioimpedance (TEB) provides a rapid, accurate, cost-effective method of optimizing the atrioventricular delay in dual-chamber pacemakers. In addition to measurements of cardiac output, TEB provides other hemodynamic indices such as systolic time interval, left cardiac work index, and end diastolic index.

[Thoracic electric bioimpedance].
Casopis lekaru ceskych, 1996So far there was, no simple non-invasive method for the assessment of the minute. Rheoplethysmographic methods developed in the seventies did not give reliable results. The submitted paper presents a new quantitative rheople-thysmographic method - thoracic electric bioimpedance.

The Historical Evolution of Bioimpedance
AACN Clinical Issues: Advanced Practice in Acute and Critical Care, 1999Thoracic electrical bioimpedance is a technology that converts changes in thoracic impedance to changes in volume over time. In this manner, it is used to track volumetric changes such as those occurring during the cardiac cycle. These measurements, which are gathered noninvasively and continuously, have become more sophisticated and more accurate with

BIOIMPEDANCE TOMOGRAPHY (ELECTRICAL IMPEDANCE TOMOGRAPHY)
Annual Review of Biomedical Engineering, 2006Electrical impedance tomography (EIT) is a relatively new imaging method that has evolved over the past 20 years. It has the potential to be of great value in clinical diagnosis; however, EIT is a technically difficult problem to solve in terms of developing hardware for data capture and the algorithms to reconstruct the images.
