Various device diagnostic parameters and corresponding default threshold values that trigger a device observation. The left column shows the various device parameters and their representative trend. The right column shows the corresponding default threshold values (see Methods for more details). Except for raw impedance and HRV, all other parameters have an observation that is triggered when the corresponding threshold is crossed. However, the availability of OptiVol observation varies with geography (refer to text for details).
