Videodensitometric Methods for Cardiac Output Measurements
Cardiac output is often measured by indicator dilution techniques, usually based on dye or cold saline injections. Developments of more stable ultrasound contrast agents (UCA) are leading to new noninvasive indicator dilution methods. However, several problems concerning the interpretation of dilution curves as detected by ultrasound transducers have arisen. This paper presents a method for blo...

امروزه استفاده از منابع انرژی پراکنده کاربرد وسیعی یافته است . اگر چه این منابع بسیاری از مشکلات شبکه را حل می کنند اما زیاد شدن آنها مسائل فراوانی برای سیستم قدرت به همراه دارد . استفاده از میکروشبکه راه حلی است که علاوه بر استفاده از مزایای منابع انرژی پراکنده برخی از مشکلات ایجاد شده توسط آنها را نیز منتفی می کند . همچنین میکروشبکه ها کیفیت برق و قابلیت اطمینان تامین انرژی مشترکان را افزایش ...
15 صفحه اولResearch utility of noninvasive methods for measurement of cardiac output.
Two noninvasive methods of cardiac index (Q) determination, pulsed Doppler echocardiography (QDop), and CO2 rebreathing (QCO2) were compared to dye dilution in eight normal volunteers. Measurements of Q were made by dye dilution (QDD) and the two noninvasive techniques under the following conditions: supine rest, after inflation of cuffs around the thighs, 35-degree head-up tilt, supine rest re...
متن کاملBioimpedance cardiography measurements of cardiac output and other cardiovascular parameters.
This paper describes impedance technique and device types, discusses hemodynamic data parameters that are available, discusses the differences between impedance cardiography and data that are derived from invasive pulmonary artery catheters, and explains how nurses can apply bioimpedance cardiography in a variety of patient populations.
متن کاملNoninvasive cardiac output measurements in patients with pulmonary hypertension.
Pulmonary hypertension (PH) is characterised by a progressive decline in cardiac output (CO) and right heart failure. NICOM® (noninvasive cardiac output monitor) is a bioreactance-based technology that has been broadly validated, but its specific application in right heart failure and PH is unknown. Cardiac catheterisation was performed in 50 consecutive patients with PH. CO measurements were p...
