CPR feedback device designed as part of the Safety, Equity, and Design (SED) Lab at the University of Toronto for improving the CPR effectiveness of bystanders in emergency first-aid scenarios.
Context
In cardiac arrest scenarios, the quality of bystander CPR plays a critical role in patient survival and recovery.
This CPR feedback device is a prototype tested with over 25 study participants to evaluate the effectiveness of audio and haptic feedback on CPR quality.
Key Features
Electrical: Arduino microcontroller, 9-axis gyroscope and accelerometer (SPI), vibrating motor
Mechanical: 3D-printed enclosure for electronics
Software: embedded firmware for device feedback and sensor reading, Python scripts for data analysis and visualization
Engineering Design Images
Python scripts developed for data visualization and organization.Poster presentation for Undergraduate Engineering Research Day at the University of Toronto.
