To extract Cardiac Output values from impedance cardiography data if subject height/weight was not recorded, set the stroke volume method to Kubicek.
Subject height and weight are not needed for the Kubicek/Rho method, but a value must be entered for height and weight for the analysis to run.
You can easily confirm that the height and weight values are not used in the analysis: take a small section of data and run the analysis twice using drastically different values for height and weight for the two different runs; you will see that the results are identical because the results do not depend on those values.
Height and weight values must be entered for Kubicek/Rho analysis when running AcqKnowledge 4.4.1 or below; the dialog box will be modified in future releases to use different prompts for different stroke volume method preferences.
High-performance mobile fNIR Imaging Systems are stand-alone functional brain imaging solutions for continuous NIR spectroscopy (NIRS). These top of the line systems provide cognitive function assessment and eliminate a great many of the drawbacks of a functional MRI. Mobile subjects are comfortable and can respond naturally in real-world situations to take a test or perform mobile […]
