We designed the Mayo BIBS EMG Device as a novel, noninvasive electromyographic (EMG) monitoring system to help healthcare professionals assess extubation readiness in intensive care unit (ICU) patients. By capturing and analyzing real-time EMG signals from interclavicular muscles, our portable device provides objective, quantitative data on respiratory muscle activity and strength, enhancing clinical decision-making for extubation.
We integrated band-pass filtering, signal amplification and custom microcontroller code to ensure precise detection and processing of weak bioelectrical signals. Our compact design includes a 3D-printed enclosure, LED indicators for user feedback and compatibility with widely available medical electrodes.
We selected electrodes for patient safety, comfort and reliable signal acquisition. We designed the device to reduce extubation failure risk, a significant cause of ICU morbidity. We minimized noise interference and optimized signal clarity, ensuring accurate data collection and interpretation. Future developments will refine electrode placement, enhance signal processing and explore seamless integration with existing ICU monitoring systems to maximize clinical impact.
