Comparison of electrical impedance and mechanical plethysmography
Journal of Surgical Research, 1978Impedance plethysmography has not had the appeal of other techniques of volume measurement. Doubts as to the validity of the technique and inconsistency in reports of the relationship of impedance measurements to other invasive and noninvasive methods of volume measurement have contributed to this lack of appeal.

Assessment of Peripheral Hemodynamics Using Impedance Plethysmography
Physical Therapy, 1986Impedance plethysmography (IPG) is a safe, noninvasive method for measuring peripheral hemodynamics. The purpose of this article is to describe the IPG technique and its potential use by physical therapists in making hemodynamic evaluations. Impedance plethysmography requires the attachment of four circumferential Mylar band electrodes around a limb ...

Measurement of cardiac output by electrical impedance plethysmography
Journal of Biomedical Engineering, 1987There are many potential applications for cardiac output measurement in clinical and experimental medicine. The most commonly used techniques are invasive procedures, requiring cardiac or arterial catheterization, a disadvantage that has restricted their wider application.

Impedance plethysmography on the arms: Respiration monitoring
2010 IEEE International Conference on Bioinformatics and Biomedicine Workshops (BIBMW), 2010A new method for extracting respiratory rate from electrical impedance measured on the arms is presented. The method requires application of only four electrodes to the subject's arms and is suitable to be used in a portable respiratory rate monitor and decision making systems. Set-Membership filtering is used to reduce the effect of motion artifact on

Effect of Positive Pressure Ventilation on Impedance Plethysmography
Chest, 1994It has been stated that positive pressure ventilation (PPV) may cause false positive impedance plethysmography (IPG) results because PPV can decrease venous outflow. We studied 36 patients who were being weaned from mechanical ventilation to determine the effect of PPV on IPG.

Quantitative electrical-impedance plethysmography for pulmonary oedema
Medical & Biological Engineering & Computing, 1977A simple expression is given for the estimation of transthoracic electrical impedance directly from externally measured dimensions of the thorax of a human subject. Clinically, the abnormalities due to an intrathoracic accumulation of fluid can be detected by comparing the estimated and the measured values of the impedances.

Impedance plethysmography: Its limitations as a substitute for phlebography
Cardiovascular Radiology, 1978Impedance plethysmography (IPG) was used to study 132 legs: 100 in normal volunteers not subjected to radiocontrast phlebography, seven in patients whose limbs were phlebographically normal, and 25 proven by phlebography to have deep venous thrombosis (DVT).
