1. A method of operating a system for measuring a physiological parameter of blood in a patient, the method comprising:

  • emitting at least one optical signal for propagation into tissue of the patient via a tissue interface assembly;

    receiving the at least one optical signal after propagation;

    identifying a propagation pathlength of the at least one optical signal; and

    processing at least the propagation pathlength to determine a state of the tissue interface assembly on the tissue.
