Claim 4:
5. An apparatus for assessing blood perfusion, said apparatus comprising:
an apparatus body;
an emitter configured to emit light at a first wavelength and a second wavelength when activated;
a first receiver and a second receiver, wherein said two receivers are disposed on said apparatus body to allow simultaneous positioning of said first receiver on a first location on a patient's skin and said second receiver on a second location bisymmetric relative to said first location;
a circuit electronically coupled to each of said two receivers and configured to measure reflected light detected by each of said two receivers;
a processor electronically coupled to said circuit and is configured to receive a first reflected light measurement from a first location and a second reflected light measurement from a second location, and to convert said first reflected light measurement to a first perfusion value and said second reflected light measurement to a second perfusion value; and
a non-transitory computer-readable medium electronically coupled to said processor and contains instructions that, when executed on said processor, perform the step of determining a difference between said first perfusion value and said second perfusion value.
