Plastic and Reconstructive Surgery, 1991
Vigilant postoperative monitoring of the buried muscle flap is critical after free transfer because early diagnosis of vascular insufficiency is essential to allow prompt correction. We have identified a monitoring method utilizing needle electrodes and impedance plethysmography that gives a beat-to-beat representation of muscular perfusion.

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

Positional Factors in Venous Impedance Plethysmography
Archives of Surgery, 1973To determine whether leg position or distance between the inner electrodes affect the magnitude of impedance change during deep inspiration, 30 adult patients (60 limbs) were studied with the Minnesota Impedance Cardiograph. Phlebography was performed in 19 limbs and correlated with the impedance findings.

Electrical Impedance Plethysmography
Archives of Internal Medicine, 1962Plethysmography has proven to be a valuable method for studying the dynamics of peripheral vascular beds in normal and pathologic states and for evaluating the effects of drugs upon these beds. Refinements of the method, such as graded outflow hindrance and stopflow studies, have permitted separation of the pulsatile arterial inflow and venous runoff ...

Advances in intracardiac impedance Plethysmography
[1990] Proceedings of the Twelfth Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2005Intracardiac impedance measurements in conjunction with microprocessor controlled signal processing and lead technology provide a great variety of practical applications, particularly for physiologic control of the pacing rate of implantable pulse generators.
