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.
Researchers use Stimulus-Response to understand human behavior. Learn how to setup five different stim-response experiments: Electrical, Haptic, Thermal, Auditory and Visual. We’ll show you a live demo of all the hardware and software, and we’ll explain how it works.
BIOPAC provides software and hardware that allow for research teams to record and analyze respiration activity in physiological experimentation. Here are a few notable studies covering HRV, EMG, and EEG measurement. DON’T STRESS (Jing Wei, Hong Luo, Si J. Wu, Paul P. Zheng, Genyue Fu, and Kang Lee) Humans encounter various stressful situations everyday at work, home, and school. Such stress when experienced at high degrees and/or […]
Alan Macy Answers Proust Questionnaire BIOPAC co-founder and R&D Director, Alan Macy, was interviewed recently by Roger Durling for the Santa Barbara Independent. The article, “The S.B. Questionnaire: Alan Macy,” provided a background excerpt of the Santa Barbara entrepreneurs’ past as well as his answers to the Proust Questionnaire. The biomedical technology developed at BIOPAC reflects an ambitious […]
