Abstract

As an essential medical monitoring device, pulse oximeters play a critical role in assessing respiratory health. This paper reviews the functions, development, and future prospects of pulse oximeters, elaborates on the working principles of pulse oximeters, including optical measurement and signal processing technologies. By analyzing the development history of pulse oximeters, it summarizes their advancements in portability, accuracy, and multifunctionality. In response to current challenges in measurement accuracy, the paper explores primary methods for improving precision. Finally, it provides an outlook on the future development directions of pulse oximeters, including high-precision measurement, AI integration, and applications in special environments. A pulse oximeter is a medical device that non-invasively monitors blood oxygen saturation. It has evolved from traditional fingertip models to smarter, more portable, and multi-functional designs, with promising future applications in telemedicine, wearable technology, and chronic disease management.

Keywords:
