1. A blood loss monitor system comprising:
a volume sensor coupled to an integration device, the volume sensor configured to gather a first data regarding a first volume of blood loss within a canister;
a second sensor coupled to the integration device, the second sensor configured to gather a second data regarding a second volume of blood loss;
an optical spectroscopy sensor coupled to the integration device, the optical spectroscopy sensor configured to gather a third data including a percentage of fluid being blood;
wherein the optical spectroscopy sensor comprises a light source, a light sensor, and a processor, and wherein the processor is configured to analyze signals collected from each of the light source and the light sensor and is configured to calculate the percentage of the fluid being blood;
wherein the second sensor is a vibration sensor, and the second volume of blood loss is based on a number of surgical wipes that have been disposed of; and
wherein the integration device is configured to calculate a total blood loss.
