Claim 27:
28. A non-transitory computer-readable medium having instructions stored thereon that, when executed by at least one processor, cause the at least one processor to perform operations for determining a hemodynamic stability of a subject, the operations comprising:
transmitting an optical signal via at least one optical fiber in a set of one or more optical fibers disposed in a heart of the subject, wherein the at least one optical fiber in the set is configured to bend with contraction and relaxation of the heart;
receiving a reflected portion of the optical signal via the at least one optical fiber, wherein a change in at least one parameter of the received reflected portion of the optical signal is indicative of an amount of bending of the at least one optical fiber due to contraction and relaxation of the heart, wherein the at least one parameter change includes a Bragg wavelength shift;
receiving at least one of a thermal signal, an ultrasound signal, or an impedance signal; and
determining the hemodynamic stability of the subject based on the Bragg wavelength shift and on a change in the at least one of the thermal signal, the ultrasound signal, or the impedance signal.
