Konig G, et al; In Vitro Evaluation of a Novel System for Monitoring Surgical Hemoglobin Loss. Anesthesia & Analgesia 2014 Volume 119 Issue 3, p 595-600

In this study, we measured surgical blood loss using a tablet computer programmed with a unique algorithm modeled after facial recognition technology. The aim of the study was to assess the accuracy and performance of the system on surgical laparotomy sponges in vitro. Mobile blood loss monitoring using the Triton system is accurate in assessing Hb mass on surgical sponges across a range of ambient light conditions, sponge saturation, saline contamination, and initial blood Hb. Utilization of this tool could significantly improve the accuracy of blood loss estimates.
