ComfortCare: Closing the Diagnostic Gap in Home Sleep Testing
- Program: Biomedical Engineering
- Course: EN.580.571 Honors Instrumentation
- Year: 2026
Project Description:
ComfortCare is a wearable, at-home sleep diagnostic designed to improve the accuracy of obstructive sleep apnea (OSA) detection by incorporating true sleep staging. Current home sleep apnea tests (HSATs) estimate disease severity using total recording time, which leads to missed diagnoses and systematic underestimation of severity. ComfortCare addresses this limitation by integrating EEG-based sleep staging with standard respiratory sensing (e.g., airflow, oxygen saturation, and respiratory effort) in a comfortable, user-friendly form factor. By enabling calculation of apnea–hypopnea index (AHI) based on total sleep time rather than recording time, the system more accurately captures sleep-dependent respiratory events, including mild and REM-related apnea. The goal is to reduce false negatives, improve severity classification, and enable earlier, more appropriate clinical intervention while maintaining the accessibility and convenience of at-home testing.
