Pulse Oximeter – 5 Things You Should Know!

Pulse Oximeter – 5 Things You Should Know!

The invention and marketing of the pulse oximeter was a huge milestone in monitoring the oxygenation of a patient’s blood levels and patient care, enabling the readings to be taken during movement of the patient and when in a relaxed state.

1. Its history goes back to scientific experiments as far back as 1800, further credit for its development combined research studies and experiments by early scientists Lambert, Beer, Bunson and Kirchhoff in 1860. Stoke and Hoppe-Seyler, Nicolai in 1932 and later Krammer and Carl Matthes.  The main principles of the pulse oximeter were developed between 1940 and 1964 by Millikan, Wood and Shaw.

2. In 1972, Takuo Aoyagi, a Japanese bio-engineer, invented the pulse oximeter after measuring oxygen saturation by sending light through the tissues. In 1978 William New, MD, Ph.D., developed the principle further after realizing that infrared and red light measures the blood.

3. In 1970 Hewlett Packard produced and marketed a large, bulky ear oximeter with a difficult to use ear piece. It weighed 35 lbs and cost $10,000. In the 1980s the product expanded onto the world market and is now being used in hospitals, clinics, medical centres, paediatric centres, in operating theatres, critical care areas and in some homes for monitoring oxygen blood levels of asthmatic patients.

4. The oximeter has been adapted, updated and minimized. They are now small and light weight, hand held models and designed to fit onto the fingers. This quick, easy, safe, non-invasive and cost effective device is continuing to make its mark on the medical field.

5. The pulse oximeter has made an enormous impact in medicine and has aided the advancement of patient care in both anaesthesia and critical care. It has been reported that the introduction of pulse oximetry coincided with 90 percent reduction in anaesthesia related deaths.
