1. A disposable sterile barrier configured to interpose a material between a tissue site and surfaces of a sensor configured to grasp the tissue site, the sensor configured to transmit optical radiation into the tissue site and to generate a signal responsive to the optical radiation after attenuation by pulsatile blood flow within the tissue site, the disposable sterile barrier comprising:
a barrier comprising a collapsible tube the barrier being made of a substantially optically transparent material;
a first portion of the collapsible tube including an open end, wherein the first portion is sized to receive a reusable optical sensor in the collapsible tube, and wherein at least a portion of the first portion is configured to be interposed between a tissue site and a first surface of the reusable optical sensor proximate an emitter of the reusable optical sensor; and
a second portion of the collapsible tube including a closed end, wherein the second portion is sized to receive the reusable optical sensor in the collapsible tube, and wherein at least a portion of the second portion is configured to be interposed between the tissue site and a second surface of the reusable optical sensor proximate a detector of the reusable optical sensor.
