Join us on November 8th as Dr. Paul Addison and Dr. Soodeh Ahani explore "Non-Contact Monitoring of Respiratory Rate for Infants in the NICU using Depth and RGB Cameras".


In our presentation, we explore non-contact respiratory rate estimation for NICU infants, delving into both depth-sensing and RGB video-based methods. We've conducted extensive evaluations with 13 infants, each monitored for 4 consecutive hours through the Mitacs Elevate program.

First, we spotlight Paul Addison's pioneering work in continuous respiratory rate monitoring using depth-sensing cameras. His research underscores the crucial role of accurate respiratory rate monitoring, a vital sign with critical clinical implications. It acts as an early indicator of acute illnesses, offering timely intervention opportunities and significantly impacting patient outcomes.

Expanding on this foundation, I introduce our innovative RGB video-based respiratory rate (RR) estimation method, tailored for sensitive NICU infants. Leveraging Eulerian video magnification (EVM), we extract subtle respiratory signals from video data. We've addressed unique NICU challenges, such as low light, shallow breathing, and swaddled infants.

A standout contribution is our adaptive peak prominence threshold estimation, ensuring accurate RR readings despite these challenges. Our method also includes automatic ROI selection based on motion signals, enabling precise breathing pulse estimation and potential disorder detection.

Additionally, Bland-Altman analysis highlights our algorithm's superior agreement with visually counted RR, surpassing impedance sensors and reference values. This demonstrates our algorithm's potential for accurate NICU RR estimation, even under complex conditions.

In conclusion, our presentation sheds light on non-contact NICU infant respiratory rate monitoring. It showcases depth-sensing and RGB video-based methods, offering a holistic view of this transformative technology's implications for neonatal care.
