Holmes A, et al; Clinical Evaluation of a Novel System for Monitoring Surgical Hemoglobin Loss. Anesthesia & Analgesia 2014 Volume 119 Issue 3, p 588-594

In this study, we assessed the accuracy and performance of the system in surgical cases. The novel mobile monitoring system provides an accurate measurement of Hb mass on surgical sponges as compared with that of manual rinsing measurements and is significantly more accurate than the gravimetric method.
