1. An apparatus comprising:
a first electrode and a second electrode configured to measure a level of sub-epidermal moisture (SEM),
an electronics package individually connected to the first and second electrodes and configured to measure a capacitance between the first and second electrodes, and
an inflatable pocket, wherein the inflatable pocket is configured to change inflation to shift levels of contact pressure between a medical device and a patient's skin, and wherein the change in inflation of the inflatable pocket is driven by a delta value from two or more SEM readings.
