Computational systems and methods for reporting information regarding appurtenances to wound dressings are described. A system can include an appurtenance to a wound dressing, including a substrate, a transmission unit, a selectively activated switch, and a projection of a size and shape to extend into an interior region of a wound dressing and configured to sample a fluid associated with a wound; a local unit, including a receiver configured to receive signals from the transmission unit, a transmitter configured to send signals to the transmission unit, a processor, non-volatile memory, and a power source; and a central assembly, including a processor, a receiver configured to receive signals from the local unit, and at least one user interface.
