Abstract
Adaptations to the OptiVol™ alert algorithm are disclosed which may reduce the number of false positive alerts while retaining the desired sensitivity. Some embodiments monitor fluid levels in patients. Some embodiments reset a cumulative index when a short-term impedance value is greater than a baseline impedance value minus a predetermined positive hysteresis value.
