Implementation of a standards-based pulse oximeter on a wearable, embedded platform

Abstract

This paper addresses software design considerations in implementing the medical information bus (MIB) standard on a wearable pulse oximeter. Underlying hardware constraints greatly influence software operation and performance. This design uses a PIC18 microcontroller with software written in C. A modified version of an MIB software implementation by Alaris medical systems will run on this hardware/software configuration. A hardware prototype has been created, and the underlying software is currently in development.
