350,000 cardiac arrests occur outside of hospitals each year, 90% of which are fatal. To increase a patient's chance for survival, adequate bystander CPR must be performed. Existing real-time feedback CPR devices don't satisfy all criteria in being intuitive, cost-effective, portable, and giving audio and visual feedback. Our final CPR device satisfies all criteria, giving both audio and visual feedback with a 110-bpm metronome and 3 LEDs that correspond to compression depth from acceleration data collected from a 9DF accelerometer. It is portable, intuitive, and costs less than $25. A designed spring box apparatus tested compressions with the device for 100 2-minute compression tests, to prove a 73% success. IRB subject tests show that the device increased CPR confidence in 96% of users.
