SS31L NONINVASIVE CARDIAC OUTPUT SENSOR
The SS31L records the parameters associated with Cardiac Output
measurements. The SS31L incorporates a precision high-frequency
current source, which injects a very small (400µA rms) current
through the measurement tissue volume defined by the placement of a
set of current source electrodes. A separate set of monitoring
electrodes then measures the voltage developed across the tissue
volume. Because the current is constant, the voltage measured is
proportional to the characteristics of the biological impedance of the
tissue volume.
Use the SS31L to measure changes in Cardiac Output under a variety of conditions: laying down, sitting
up, standing up, and post-exercise.
Use on stationary subjects; the SS31L is sensitive to motion artifact.
