Tetrapolar Low-Cost Systems for Thoracic Impedance Plethysmography
IEEE International Symposium on Medical Measurements and Applications, 2018Bioelectrical impedance analysis applied to the pneumographic investigation is a technique for monitoring the breathing activity through the measurement of variations in the trans-thoracic electrical impedance.

Impedance Plethysmography: Correlation with Contrast Venography
Radiology, 1977Impedance plethysmography is a noninvasive, indirect test for deep venous occlusion in the lower limbs. The results of ascending contrast venography impedance plethysmography have been compared in 315 limbs. Impedance plethysmography was positive in 77 of 79 limbs with acute deep vein thrombosis proximal to the calf.

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.

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 ...

Clinical Orthopaedics and Related Research, 1989
Impedance plethysmography (IPG) is a useful noninvasive detection of proximal segment thrombosis. Seven hundred patients treated with total hip arthroplasty were examined preoperatively and several times postoperatively using this technique. Twenty-one abnormal IPG results were obtained, and venography confirmed that 12 of these patients had proximal ...

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.
