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.
Easily record great ECG data and derived signals for heart rate, RR interval, and R-wave amplitude. BIOPAC’s new Smart Amplifiers are designed for great data. Smart Amplifiers improve performance by amplifying the physiological signal close to the subject, which allows a high-level voltage connection to the data acquisition system and reduces noise artifact.
