1. A system for monitoring an intravascular infusion, the apparatus comprising:
- a sensor configured to emit a first percutaneous electromagnetic signal and to receive a second percutaneous electromagnetic signal, the second percutaneous electromagnetic signal including at least one of a reflection, scattering and diffusion of the first percutaneous electromagnetic signal; and
antiperspirant configured to be disposed at a target area of epidermis, wherein the first and second percutaneous electromagnetic signals pass through the target area.

Abstract
A system and method include a sensor overlying a target area of epidermis to aid in diagnosing subcutaneous fluid leakage. The system includes an antiperspirant and an adhesive coupling the sensor and epidermis. The antiperspirant mitigates moisture content variation of the target area, which the inventors discovered is a source of unreliable indications that an infiltration or extravasation event has occurred.
