Adrenomedullin refines mortality prediction by the BODE index in COPD: the "BODE-A" index.
The BODE (body mass index, airflow obstruction, dyspnoea, exercise capacity) index is well-validated for mortality prediction in chronic obstructive pulmonary disease (COPD). Concentrations of plasma pro-adrenomedullin, a surrogate for mature adrenomedullin, independently predicted 2-year mortality among inpatients with COPD exacerbation. We compared accuracy of initial pro-adrenomedullin level...
متن کاملBode Diagrams of Transfer Functions and Impedances
In the design of a signal processing network, control system, or other analog system, it is usually necessary to work with frequency-dependent transfer functions and impedances, and to construct Bode diagrams. The Bode diagram is a log-log plot of the magnitude and phase of an impedance, transfer function, or other frequency-dependent complex-valued quantity, as a function of the frequency of a...
متن کاملRobust controller design based on generalized Bode envelopes
We propose simple tools for robust design of controllers for SISO linear systems with or without uncertainty. These tools are based on the generalization of frequency domain, where the uncertainty is defined by generalized Bode envelopes (GBE). The utilization of generalized Nyquist and Mikhailov theorems, which uses the number of GBE crossings with certain predefined horizontal lines, to deduc...
متن کاملBode Plots of First and Second Order Systems
The objective of this lecture is to provide you with some background on the use of transfer functions to perform the so-called frequency response analysis of dynamic systems, also known as analysis based on Bode plots. This method will be later used in the design of control systems.
متن کاملThe modified BODE index: validation with mortality in COPD.
Peak oxygen uptake (V'(O(2))) remains the gold standard measurement of exercise capacity and has been associated with survival. A modified BODE (body mass index, airflow obstruction, dyspnoea, exercise capacity) index replacing the 6-min walk distance (6MWD) with V'(O(2)) as % predicted (mBODE%) has been developed and found to have excellent correlation with the conventional BODE index. The obj...
