Claim 16:
17. An apparatus for assessing blood perfusion, said apparatus comprising:
a substrate configured to be placed against a surface of a patient's skin,
a plurality of emitters that are disposed on said substrate at a respective plurality of positions,
where each of said plurality of emitters is configured to emit light at a first wavelength and a second wavelength when activated,
a plurality of receivers that are disposed on said substrate at a respective plurality of positions, a circuit electronically coupled to said plurality of receivers and configured to measure reflected light of a portion of said plurality of receivers and provide a plurality of information regarding said reflected light,
a processor electronically coupled to said circuit and configured to receive said plurality of information regarding said reflected light from said circuit and convert said plurality of said information regarding said reflected light into a respective plurality of perfusion values, and
a non-transitory computer-readable medium electronically coupled to said processor and comprising instructions stored thereon that, when executed on said processor, perform the steps of:
identifying from said plurality of perfusion values a first receiver and a second receiver that are located at first and second positions that are bisymmetric with respect to said patient's skin, and
comparing a first perfusion value that is associated with said first receiver with a second perfusion value that is associated with said second receiver.
