Pulse oximeters are widely used in hospitals and clinics to monitor blood oxygen levels. These small, noninvasive devices ...

Typically clipped over a finger (though a toe or ear lobe works, too), a pulse oximeter transmits light from sensors on one side of the device through the body part to sensors on the other side.

In this 2025 product transparency update, BloodVitals details how its pulse oximeter supports real-time blood vitals tracking ...

Note that pulse oximetry is the non-invasive measurement of the oxygen saturation (SpO). Oxygen saturation is defined as the amount of oxygen dissolved in blood, based on the detection of Haemoglobin ...

The pulse oximeter was invented in 1974 by Japanese bioengineer Dr. Takuo Aoyagi, who died at the age of 84 in 2020 – the same year Covid-19, a disease whose symptoms are monitored with pulse ...

What is pulse oximetry? Pulse oximetry is an easy way to find if your lungs and heart are working fine and oxygen supply is proper. It helps in finding out whether all the body parts are receiving ...

Editor’s Note: Thank you to Kendall Castor-Perry for this detailed look at pulse oximetry. The author makes use of his company’s PSoC architecture as an example implementation, but the information ...

Many people first learned about a pulse oximeter in the early days of the pandemic, after doctors warned that some patients with Covid-19 develop a form of oxygen deprivation called “silent ...

Source Reference: Fawzy A, et al "Clinical outcomes associated with overestimation of oxygen saturation by pulse oximetry in patients hospitalized with COVID-19" JAMA Netw Open 2023; DOI: 10.1001 ...

Researchers show that pulse oximetry, which is a gatekeeper in treatment decisions for COVID-19 patients, overestimates blood oxygen levels in people of color. In a new study involving more than ...

The concept behind pulse oximetry had been “denied” by a skeptical supervisor at Nihon Kohden, Dr. Aoyagi recalled, and he was kept from working on the device until 1985.
