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.

The Mobita 32-Channel EEG recording system was used in research examining if physiological data can be used to predict truly random events that correspond to perceptual stimuli. Baumgart, et al. from the University of California Santa Barbara utilized a quantum random number generator (qRNG) to choose from three randomized conditions: light, sound, and no stimulus. […]
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 in monitoring respiration and cardiovascular activity. The coupling between peripheral microcirculation and slow breathing: The purpose of this study was to investigate the coupling of breathing movements and microcirculatory blood […]
