Factors that Affect Bioimpedance Data

USAGE STATEMENT

Bioimpedance methods to perform stroke volume and cardiac output measurements, via application of electrodes on the neck and torso, are considered by BIOPAC to be research and educational tools.

Historically, there have been numerous research efforts to measure stroke volumes and cardiac outputs using bioimpedance techniques. The performance of these systems are subject to evolving algorithms. New bioimpedance methods, such as TREV (TransRadial Electrical bioimpedance Velocimetry), are examples showing new promise in this area. Additionally, machine learning strategies are beginning to accommodate the variabilities of bioimpedance methods, due to electrode type, placement, body position, movement artifact and electrical signal filtering.

Research is ongoing, as bioimpedance techniques offer profound noninvasive advantages, compared to thermodilution and similar “gold-standard” historical methods for measuring stroke volume and cardiac output. BIOPAC is committed to continuing to offer educational and research solutions for the application of bioimpedance methods, to measure cardiovascular parameters, despite the present “state of the art” showing these measures to be generally more useful for determining relative changes versus absolute values.

ECG Electrocardiogram Amplifier for MRI

The ECG100C-MRI Electrocardiogram Amplifier records electrical activity generated by the heart and will reliably record ECG from humans, animals and isolated organ preparations. The amplifier output can be switched between normal ECG output and R-wave detection. The R-wave mode outputs a smoothed pulse with the occurrence of each R-wave. The exact timing of the R-wave […]
