Abstract: An example system includes a memory and one or more processors in communication with the memory and configured to receive patient information and select at least one negative-pressure wound therapy (NPWT) parameter setting based on a causal model that determines 5 current causal relationships between a set of NPWT parameter settings and a set of effects of controlling the fluid at the wound site. The one or more processors are further configured to control the fluid at the wound site via the NPWT dressing based on the selected at least one NPWT parameter setting.

Abstract: An optical stack for sensing a presence of an analyte is provided. The optical stack includes a sensor material. The sensor material includes a first optical response including a first optical property having a second value in response to an excitation signal including the first optical property having a first value different from the second value. The first optical response includes a second optical property sensitive to the presence of the analyte. The optical stack includes a first optical film disposed proximate the sensor material and includes a third optical property having respective third and fourth values in response to the respective first and second values of the first optical property. The third value is different from the fourth value by at least a factor of 2.

Abstract: A method and system for tissue impedance measurement are disclosed. In examples, the system comprises electrical contacts configured to be coupled to a first tissue and a first device configured to apply a first electrical signal to the first tissue via the electrical contacts. The system further comprises a second device configured to determine a first impedance phase angle of epithelial tissue of the first tissue site based on the first applied electrical signal, determine a baseline impedance phase angle of epithelial tissue corresponding to a second tissue, determine information indicative of epithelial tissue characteristics based on a ratio of the first impedance phase angle and the baseline impedance phase angle, and output information indicative of the epithelial tissue characteristics.
