Apparatus and methods for determining damaged tissue using sub epidermal moisture measurements
The present disclosure provides apparatuses and computer readable media for measuring sub-epidermal moisture in patients to determine damaged tissue for clinical intervention. The present disclosure also provides methods for determining damaged tissue.
1. A method for ensuring contact of one or more sensors to a skin surface, the method comprising:
contacting a first surface of an apparatus with said skin surface, wherein said apparatus comprises said one or more sensors and one or more contact sensors surrounding each of the said one or more sensors disposed on said first surface,
obtaining one or more capacitance signals from said one or more sensors upon a determination that at least one of said one or more contact sensors surrounding said one or more sensors is in contact with said skin surface,
converting said one or more capacitance signals to one or more sub-epidermal moisture (SEM) values,
determining a maximum SEM value and a minimum SEM value from said one or more SEM values, and
calculating a delta difference by subtracting said minimum SEM value from said maximum SEM value.
2. The method of claim 1 , wherein said determination that at least one of said one or more sensors is in contact with said skin surface comprises determining that at least one of said one or more contact sensors surrounding said one or more sensors is in contact with said skin surface.
3. The method of claim 1 , further comprising adjusting said apparatus for contact of at least one of said one or more bioimpedance sensors with said skin surface.
4. The method of claim 1 , wherein said one or more contact sensors are selected from the group consisting of: one or more pressure sensors, one or more light sensors, one or more temperature sensors, one or more pH sensors, one or more perspiration sensors, one or more ultrasonic sensors, one or more bone growth stimulator sensors, and a combination thereof.
