The first identification band is securely fixed to a first location on the patient and the second identification band is securely fixed to a second location on the patient. The first and second identification bands are connected with a bridging band. The signal cable is connected to a diagnostic test monitoring system and the patient's oxygen saturation is monitored. The first and second identification bands are configured to evidence tampering when removed. ## Claims ### Claim 1 A system comprising: a first identification band comprising a first aperture formed by the first identification band being in the form of a first loop; a second identification band comprising a second aperture formed by the second identification band being in the form of a second loop, the first and second identification bands show evidence of tampering upon removal; and a bridging band connected to the first and second identification band, wherein the first identification band, the second identification band, and the bridging band are formed from a single piece of material; wherein the first identification band is configured to be placed around a finger of a patient, the finger of the patient extending through the first aperture, and the second identification band is configured to be placed around a wrist of the patient, the wrist of the patient extending through the second aperture. ### Claim 2 (depends on 1) The system of claim 1, wherein the first identification band and the second identification band each comprise serial numbers. ### Claim 3 (depends on 1) The system of claim 1, wherein the first identification band, the second identification band each comprise matching serial numbers. ### Claim 4 (depends on 1) The system of claim 1, wherein the evidence of tampering comprising shredding, tearing, discoloration, delamination, change in physical dimensions, or necking. ### Claim 5 (depends on 1) The system of claim 1, wherein at least one of the first identification band, the second identification band, and the bridging band, is treated with pressure sensitive ink that shows the evidence of tampering. ### Claim 6 (depends on 1) The system of claim 1, wherein the bridging band comprises an adhesive layer. ### Claim 7 A system comprising: a first identification band comprising a first aperture formed by the first identification band being in the form of a first loop; a second identification band comprising a second aperture formed by the second identification band being in the form of a second loop, the first and second identification bands show evidence of tampering upon removal; and a bridging band connected to the first and second identification band, the first identification band, the second identification band, the bridging band are formed from a single piece of material, the evidence of tampering comprising shredding, tearing, discoloration, delamination, change in physical dimensions, or necking, and the first identification band and the second identification band each comprise matching serial numbers. ### Claim 8 (depends on 7) The system of claim 7, wherein the first identification band is configured to be placed around a finger of a patient, the finger of the patient extending through the first aperture, and the second identification band is configured to be placed around a wrist of the patient, the wrist of the patient extending through the second aperture. ### Claim 9 (depends on 7) The system of claim 7, wherein at least one of the first identification band, the second identification band, and the bridging band, is treated with pressure sensitive ink that shows the evidence of tampering. ### Claim 10 (depends on 7) The system of claim 7, wherein the bridging band comprises an adhesive layer.
