“By applying a robust machine learning model to our app, DS helped us create a scalable and accurate solution to improve the operating room experience for the anesthesia team and the patient. They are true collaborators.”

Justin Scott, M.D., FASAchief executive officer & founder

The challenge

Anesthesiologists generally provide care for several patients at once, making it difficult to continually monitor multiple patients in different operating rooms. Vigilant Medical Solutions designed a remote monitoring app – the first of its kind – that allows anesthesiologists to monitor the vital signs of multiple patients simultaneously.

Vigilant approached us to refine the user interface and improve the app’s performance. To display vital signs accurately from multiple monitors, Vigilant needed an advanced machine learning model that could extract and transcribe clinically meaningful data into accurate metrics from multiple operating rooms – all onto a single smartphone screen.

The solution

Our developers used advanced machine learning to capture, define, and structure images from patient monitors in the OR, translating patient vitals – with 99.9% accuracy – directly to a caregiver’s handheld mobile device screen.

With custom alerts and real-time data, the medical staff are alerted the moment their patient’s vitals go beyond pre-set parameters or their individualized alerts.


Remote monitoring in hospitals

Justin Scott, M.D., a board-certified anesthesiologist, envisioned a mobile app that could enable anesthesia teams to monitor multiple surgical patients simultaneously. As an anesthesiologist within a large hospital network, Dr. Scott understood the challenges associated with overseeing vital signs of multiple patients at once.

To improve operating room surveillance and accelerate clinician intervention, we needed to build and apply a machine learning model that could accurately transcribe data from various types of operating room monitors to a physician’s mobile device in real time.


Machine learning in healthcare

Analyzing over a million images on a variety of operating room monitors, we were able to create an intelligent and precise model that can quickly analyze and translate complex data from monitors into metrics on a mobile app, with 99.9% accuracy. The monitor-agnostic system gets smarter over time, works with a wide range of hospital technologies, and can be used beyond the operating room, such as in a patient’s home.

UI & branding refresh: before & after

During the initial first phase of our engagement with Guardian, we performed a UI and branding redesign for Guardian’s website. In the redesign, we focused on inclusive design for diversity & accessibility and SEO.

operating room remote monitoring


Through advanced machine learning models, we transformed the Guardian app prototype into a fully developed remote monitoring app that can transmit patient vital signs in real time with 99.9% accuracy.

The Guardian app – the first of its kind – is now available to hospitals and anesthesia teams throughout the nation. The app allows clinicians to continuously track vital signs of multiple patients simultaneously, accelerates clinician intervention, decreases liability exposure, and improves patient outcomes.
