The Pulse Oximeter Jun- 2012 Abstract This paper explores the definition of the pulse oximeter, and also its uses and benefits from Mosby's Dictionary of Medicine, Nursing, & Health Professions and four published articles, that report on results from research conducted on online (Internet) and offline (non-Internet). The articles, however, vary in their definitions and uses of the pulse oximeter. This noninvasive method of measuring the saturated hemoglobin is a useful screening tool for determining basic respiratory function. The Pulse Oximeter: its use and its benefits Introduction The objective of this paper is to describe and explain the uses and benefits of the pulse oximeter as used in health care. There are 5 types of applications of the pulse oximeter: ear, finger, forehead, intracardiac oximeter, and bridge of the nose. The purpose of this research is to concentrate on the finger application of the pulse oximeter. The original oximeter was made by Milliken in the 1940s1. The precursor to today's modern pulse oximeter was developed in 1972, by Aoyagi at Nihon Kohden using the ratio of red to infrared light absorption of pulsating components at the measuring site. It was commercialized by Biox in 1981. The device did not see wide adoption in the United States until the late 1980s. Definition Oximetry It is a photodiagnostic method of monitoring arterial blood oxygen saturation (SaO2). Oximetry is commonly used to titrate levels of oxygen in hospitalized patients. It is used for monitoring the patient’s oxygenation status during the perioperative period or any other time of heavy sedation, during mechanical ventilation, and in many clinical situations such as pulmonary rehabilitation programs and stress testing3. 3.
