Pulmonary impedance
WebHowever, the pulmonary impedance hampers venous return through the pulmonary vascular bed leading, like any dam wall or bottleneck, to congestion upstream and restricted flow downstream .6, 7 The majority of the clinical and physiological ailments in a Fontan circuit are due to the upstream venous congestion and the downstream decreased output. WebBackground: Electrical Impedance measurements can be used to estimate the content of intra-thoracic air and thereby give information on pulmonary ventilation. Conventional Impedance measurements mainly indicate relative changes, but no information concerning air-volume is given.

Impedance variations measured by EIT due to a change in thoracic air content represent the largest and most studied signal, allowing the measurement of end …
WebVascular resistance is the resistance that must be overcome to push blood through the circulatory system and create flow.The resistance offered by the systemic circulation is known as the systemic vascular resistance (SVR) or may sometimes be called by the older term total peripheral resistance (TPR), while the resistance offered by the pulmonary … WebImpedance audiometry was performed as part of the routine clinical examination in a consecutive series of more than 400 patients with various types and degrees of hearing impairment. An electroacoustic bridge (Madsen, ZO 70) was used to carry out the measurement of tympanometry, acoustic impedance, and threshold for the acoustic reflex.
WebThe pulmonary bed behaved as a quasilinear system, within the limits of accuracy of the methods employed and the range of frequencies tested, and analogies with linear models like the simple transmission line are not unreasonable. Pulmonary vascular hydraulic input impedance was measured in 13 anesthetized openchest dogs with normal sinus rhythm, …
