Bioelectric impedance measurement for fluid status assessment.
BACKGROUND Adequacy of body fluid volume improves short- and long-term outcomes inpatients with heart and kidney disorders. Bioelectrical impedance vector analysis (BIVA) has the potential to be used as a routine method at the bedside for assessment and management of body fluids. METHODS Impedance (Z vector) is a combination of resistance, R (function of intra- and extracellular fluid volume)...
متن کاملMicrofabricated Multi-frequency Particle Impedance Characterization System
We have developed a microfabricated flow-through impedance characterization system capable of performing AC, multi-frequency measurements on cells and other particles. The sensor measures both the resistive and reactive impedance of passing particles, at rates of up to 100 particles per second. Its operational bandwidth approaches 10 MHz with a signalto-noise ratio of approximately 40 dB. Parti...
متن کاملFast impedance measurement method using Laplace transformation
The paper presents the impedance measurement method using a real-life step pulse as a perturbation signal and Laplace transformation as a tool for analyzing the response of the object under test. The method is addressed to explore different technical object (like anticorrosion coatings, gas sensors, ceramics, dielectrics biological tissues etc.) when the measurement time cannot be long. The pre...
متن کاملDevelopment of Multi-frequency Electrical Impedance Spectroscopy (EIS) System for Early Detection of Breast Cancer
Breast Cancer is among the top five causes of cancer death and the topmost cause among women worldwide. The early diagnosis through simple, non-invasive and inexpensive screening can provide great deal of aids. Multi-frequency Electrical Impedance Spectroscopy (EIS) is quite attractive in this context as the instrumentation is relatively simple and research has demonstrated application in breas...
متن کاملbuckling of viscoelastic composite plates using the finite strip method
در سال های اخیر، تقاضای استفاده از تئوری خطی ویسکوالاستیسیته بیشتر شده است. با افزایش استفاده از کامپوزیت های پیشرفته در صنایع هوایی و همچنین استفاده روزافزون از مواد پلیمری، اهمیت روش های دقیق طراحی و تحلیل چنین ساختارهایی بیشتر شده است. این مواد جدید از خودشان رفتارهای مکانیکی ارائه می دهند که با تئوری های الاستیسیته و ویسکوزیته، نمی توان آن ها را توصیف کرد. این مواد، خواص ویسکوالاستیک دارند....
