There are many finger pulse oximeters available for at-home use, and knowing how you will use the device will help inform your decision. While they may not be 100-percent accurate in their readings, ...

A normal blood oxygen level is between 95%-100% SpO2 on a pulse oximeter. Here's how to use an oximeter at home.

A pulse oximeter works by using a beam of light to detect oxygen carried in red blood cells after being attached to the tip of the finger or ear. It provides a reading of the oxygen saturation ...

Patients with a fingertip pulse-oximeter reading of 94 percent or more but whose blood tests showed lower levels were deemed to have an unrecognized need for Covid therapy.

Early in the COVID-19 pandemic, research from the University of Michigan uncovered inaccuracy in readings based on race when using pulse oximeters, finger-tip devices used to determine how much ...

Pulse oximeters may overestimate blood oxygen levels for patients with darker skin and these false readings can lead to inaccurate diagnoses and the wrong treatments, according to several studies.

The data also showed that 10.2% of Black patients had pulse oximeter readings at least 15 percentage points higher than their blood gas readings, compared with 7.3% of White patients.

Due to faulty oximeter readings, non-white patients were more likely to receive delayed Covid-19 treatments like dexamethasone or remdesivir, which can help reduce death and hospitalizations.
