Design of a Bluetooth-Enabled Wireless Pulse Oximeter

Abstract Design of a Bluetooth-Enabled Wireless Pulse Oximeter Abstract—Hospitals today offer no alternative to the equipment used for measuring oxygen saturation and heart rate. As such, biomedical engineering and pulse oximetry concepts were explored in an attempt to create a device capable of the same functionality as standard wired devices found in hospital rooms around the world. In order to do this, it was necessary to study technologies involved and to build a working prototype based on other wired and wireless designs. Research involved a number of different types of design options, as well as the theory behind the calculation involved with the device. This computer engineering senior design project consists of a wireless pulse oximeter which uses Bluetooth technology to communicate with the data display module. Two different designs were first devised: one that made use of the wired technology for testing, and another one that represented the final prototype of the intended wireless design. These two were extensively tested until it was determined where the prototype was good and where it could improve. The goal of the design was to make a wireless (Bluetooth-enabled) pulse oximeter, with identical functionality to a wired device. Added features included accuracy and reliability, as well as size and power efficiency. Test results concluded that these goals were obtained, and the ideas found will benefit future projects that are based off this design.
