Overview

The Triton System by Gauss Surgical is an innovative mobile monitoring system that leverages artificial intelligence (AI), machine learning, and computer vision algorithms to provide real-time, accurate estimation of blood loss during surgical procedures and labor and delivery. Traditionally, blood loss has been estimated visually or by gravimetric methods, which are often inaccurate and imprecise, leading to potential under or overestimation and suboptimal clinical decisions.

The system operates as a mobile application on Apple iPads and iPhones, allowing clinicians to capture images of blood-soaked surgical sponges and collected fluids in canisters. These images are sent to a cloud-based platform where proprietary algorithms analyze the hemoglobin mass, distinguishing between blood and non-sanguineous fluids like saline or other body fluids. The estimated blood loss is then returned to the operating room staff in real-time, typically in less than 10 seconds.

Triton is designed to seamlessly integrate into existing surgical workflows with minimal training. It also aids in counting surgical sponges, records and displays case-specific blood components infused over time, and can calculate estimated blood volume from hemoglobin mass and patient serum hemoglobin values. The system has demonstrated improvements in patient outcomes, including earlier recognition of hemorrhage, earlier interventions, reduced blood transfusions, and shortened lengths of hospital stay.

What Physicians Need to Know

Maternal Health Monitoring
The Triton System uses computer vision and machine learning to provide real-time, quantitative measurement of surgical and obstetric blood loss. It analyzes images of surgical sponges and canisters to accurately estimate hemoglobin content and overall blood loss, even with complicating factors like irrigation fluid or ambient lighting. This technology helps in the early recognition of maternal hemorrhage, which is a leading cause of maternal mortality.
Labor & Delivery Support
The Triton System is specifically designed to support labor and delivery by providing accurate blood loss measurements during both vaginal and cesarean deliveries. For C-sections, it captures images of sponges and canisters. For vaginal deliveries, Triton QBL streamlines workflow by automatically calculating blood volume of weighed items and can trigger hemorrhage alerts based on custom protocols. Studies have shown that using Triton is associated with improved recognition of postpartum hemorrhage and earlier intervention.
Postpartum Care Tools
Triton aids in postpartum care by providing accurate blood loss data during delivery, which is crucial for managing potential postpartum hemorrhage. Early and accurate detection of blood loss can lead to earlier clinical intervention, reducing complications and improving patient outcomes.
Physician Tip

The Triton System offers a more objective and accurate method for estimating blood loss compared to traditional visual estimation or gravimetric methods, which are often inconsistent and can lead to underestimation in major surgeries or overestimation in minimal blood loss scenarios. Utilizing this system can lead to earlier detection of hemorrhage, potentially reducing the need for transfusions and shortening hospital stays. It is particularly valuable in labor and delivery settings for managing maternal hemorrhage.

The Triton System operates as a mobile application on Apple iPad devices, utilizing the device's camera to capture images for analysis. The system uses cloud-based processing for its algorithms. It can integrate with custom hemorrhage protocols to trigger alerts.

Frequently Asked Questions

The Triton System uses AI and computer vision on Apple iPhones and iPads to accurately measure blood loss during labor, surgery, and other medical procedures. For C-sections, nurses hold blood-soaked sponges to an iPhone, and the app uses algorithms to assess blood loss. For vaginal deliveries, it integrates with a Bluetooth smart scale to quantify blood loss by weight. The system can distinguish between blood and non-sanguineous fluids, integrate custom hemorrhage protocols, and trigger alerts for excessive blood loss.
The Triton System is FDA-cleared and CE Marked for blood loss monitoring in surgery and obstetrics. While the system itself has regulatory clearance, OB/GYN practices using AI tools must also adhere to HIPAA Privacy Rule compliance, which includes designating a privacy official, implementing written policies for data handling, training staff, and conducting risk analyses to protect patient health information.
Traditionally, blood loss has been visually estimated by providers, which is known to be inaccurate and imprecise. Other methods include gravimetric assessment (weighing sponges and pads), but these can be inaccurate due to confounding fluids like irrigation or amniotic fluid and are cumbersome. While other AI applications exist in OB/GYN for areas like ultrasound, fetal heart rate interpretation, and predictive modeling, the Triton System is specifically designed for quantitative blood loss monitoring using computer vision.
While the Triton System offers improved accuracy over visual estimation, early studies noted a need for further validation in an OB population. Additionally, like all AI models, the Triton System's effectiveness relies on the data it receives, and there's a general concern that AI models can exhibit biases if they don't represent accurate patient demographics. Challenges also remain concerning the validation of AI algorithms across diverse populations and the inclusion of sociodemographic variables.
The Triton System is designed to integrate seamlessly into the sponge-counting process and can embed custom hemorrhage protocols and alerts based on quantified blood loss thresholds. This real-time guidance facilitates communication and rapid response during an emerging hemorrhage. While the Triton system itself is a specialized application, many modern OB/GYN EHR systems are designed to streamline workflows, integrate with labs and imaging, and support comprehensive documentation, which would be crucial for a holistic approach to patient care.
