The document discusses the development of a device to improve cardiopulmonary resuscitation (CPR). It notes that performing CPR correctly is difficult in stressful situations, which can lead to injuries or ineffective treatment. The goal of the project was to create a device that makes CPR motions more mechanical, efficient and precise to relieve stress and improve outcomes. The device was programmed using PIC assembly language to flash a light in a timed pattern and sound a buzzer, then loop continuously until deactivated. The project was mentored by a physician's assistant.

2. Introduction
• The human body needs a constant circulation of
blood pumped from the heart in order to keep the
cells oxygenated
• Without oxygen, cells begin to die, ending with
death of the brain and eventually, the body
• When performing CPR the goal is to restart the heart
or keep it pumping until professional medical aid is
available

3. Problem
• People’s reactions are limited in stressful
situations
• If CPR is performed incorrectly
– Cracked or broken ribs/sternum
– Irregular heartbeat
– Air flows into stomach
– Death

4. Goals
• Relieve the stress of performing CPR
• Making simple motions more
– Mechanical
– Efficient
– Precise

6. Program
•
•
•
We used PIC Assembly
language and MPLAB X IDE
to write and compile our code
We had to constrain the chip so the light
flashed once every .6 seconds thirty times
and then to have the buzzer sound twice,
2 seconds apart
We also had to set the chip to only start
after we pressed the button and to go on a
constant loop until the button is pressed
again
