He, with the help of a couple microcontrollers, some sensors, and an LCD screen, teaches basic CPR. He was created by three students from Cornell University, Rameez Qurashi, Sungjoon Park, and Haoyuan Chen, as a final project for one of their Electrical and Computer Engineering classes in the fall of 2012.

The trio’s goal was to make a CPR training dummy. They thought it was important to create a system like this one, a system that allows people to learn CPR on their own with both instruction and hands-on practice; typical dummies and live instructors can be expensive, and not everyone lives in an area in which CPR classes are offered.

How does he work?

To put it simply, the dummy is rigged with sensors that allow a person performing CPR to be guided through the process and critiqued along the way.

When programming the dummy and deciding which sensors to use, the students focused on the two main components that CPR is broken down into: chest compressions and ventilations. Sensors in the chest of the dummy monitor the strength, frequency, and number of compressions. And sensors behind the face of the dummy monitor the openness of the airway, the number and frequency of breaths, and whether or not the nose is being pinched shut.

The creators also programmed the dummy with 2 modes: practice mode and test mode. When in practice mode, a trainee will be guided through the CPR process step by step. When in test mode, the quality of the CPR will be directly assessed.
