Use the SS31L to measure changes in Cardiac Output under a variety of conditions: laying down, sitting up, standing up, and post-exercise. Use the Kubicek equation to determine Stroke Volume and Cardiac Output. To use the SS31L for respiration measurements, observe the associated variation in the Impedance Magnitude “Z” signal.
The SS31L simultaneously measures Impedance Magnitude (Zo; labeled “Z” on the module) and Derivative of Impedance Magnitude (dZ/dt; labeled “DZ” on the module). Use with EL506 Bioimpedance Strip Electrodes, and use on stationary subjects—the SS31L is sensitive to motion artifact.
See BSL PRO Lesson H21 Impedance Cardiography for sample SS31L setup and data.
