When a patient has falsely elevated SpO 2 readings from a pulse oximeter, they may be at heightened risk for hidden hypoxemia, which occurs at higher incidence among patients from racial and ethnic minority groups than among the general population, and is associated with higher mortality rates. The most accurate way to measure true blood hemoglobin oxygen saturation levels is by taking a sample of a patient’s arterial blood, which requires inserting a needle into the radial artery in the wrist or putting in an arterial line-procedures that are uncomfortable for patients and cannot be done as regularly or as easily as taking measurements with a pulse oximeter.

Pulse oximeters measure how much light passes through the skin to estimate how much oxygen is in a patient’s red blood cells. “It has real meaning for the patients that we care for because we can track back racial disparities in treatment to these differences in measurements.” We use that estimate to make clinical decisions, such as how much supplemental oxygen to give a patient,” said corresponding author Eric Gottlieb, HMS clinical fellow in medicine at Brigham and Women’s. “It’s important to keep in mind that pulse oximeters give us an estimate, but it’s more than just a number.

The researchers found that, compared to white patients, Black, Hispanic, and Asian patients treated in intensive care units had greater discrepancies between blood saturation levels detected using pulse oximeters versus levels detected in blood samples and received less supplemental oxygen than white patients. This new study, published July 11 in JAMA Internal Medicine, finds evidence that those inaccuracies may also be associated with disparities in care. It’s been known for decades that skin pigmentation and melanin can affect a pulse oximeter’s ability to accurately measure oxygen saturation. Placed on a patient’s finger or ear lobe, pulse oximeters are an easy way to quickly get a measure of blood oxygen saturation (SpO 2), an important measure of how well they are breathing on their own or whether they need supportive treatment.īut, according to a new study led by Harvard Medical School researchers at Brigham and Women’s Hospital and Beth Israel Deaconess Medical Center, the device may be contributing to disparities in care based on a patient’s race. Most patients are familiar with the pulse oximeter from visits to the doctor’s office.

It is an ideal tool that helps determine a decrease in blood oxygen levels allowing one can seek medical care at an early stage if required. The device is painless and easy to use and easy to read with results displayed on the panel provided. Pulse oximeters measure differences in the frequencies of light absorbed by the oxygenated and deoxygenated haemoglobin to provide accurate oxygen levels in the blood. The pulse oximeter is crucial for those who are likely to suffer from various health conditions like asthma, heart attack, lung cancer, anaemia and other viral infections, which impacts the oxygen levels in the blood. It helps monitor the patient’s capability to manage strenuous activity based on their heart rate and oxygen saturation levels. It is a small device that is clamped on the fingertips to test how well blood pumps oxygen through the body. A pulse oximeter is a non-invasive device used to measure a person’s blood oxygen levels.
