Have you ever taken a First Aid & CPR training course? Don’t you just love the realism of the dummy mannequins you get to practice on? [Park, Qurashi, & Chen], who are students of Cornell University, thought the dummies could use an intelligent upgrade.
It’s the final project for their electrical and computer engineering course ECE 4760. And what they’ve done is successfully created a budget friendly CPR not-so-dumb dummy using the venerable ATmega1284 microcontroller.
The dummy can sense when chest compressions are given, if the nose is plugged properly when breaths are given, if the head is tilted back properly to open the airway, and it even makes use of a microphone to detect if breaths are given properly! While it does this, it uses LED eyes and an LCD screen to provide training feedback to the student. Once the students are sufficiently practiced, it also has a “real” mode that doesn’t give you any feedback to make sure the students truly learned the technique.
There’s tons of information on their final report, so if you happen to teach First Aid and want to do something different — check it out by clicking the link above. We really like the idea of enhancing training equipment, like this realistic heart rhythm simulator that [Addie] built.
Oh and talk about coincidence, I had just taken a First-Aid training course last week! And having to pretend to give CPR to the current dummy on the market… they could definitely use an upgrade.
