![]() When reached for comment, an Apple spokesperson told Ars Technica: But yesterday's ruling resulted in the stay being lifted, forcing Apple to either stop selling the watches or to continue selling them but with the disputed feature removed. The company received a temporary stay that enabled it to sell the watches with the questioned capabilities from December 27 until 5 pm ET yesterday. In January 2023, the US International Trade Commission (ITC) ruled that Apple Watches infringe two patents for light-based pulse oximetry functionality and components owned by California-headquartered Masimo.Īfter US President Joe Biden declined to veto the ruling, Apple filed an appeal and pulled the watches on December 21. ![]() Our determination is governed by four factors: (1) whether the movant has made a strong showing of likelihood of success on the merits (2) whether the movant will be irreparably harmed absent a stay (3) whether issuance of the stay will substantially injure the other parties interested in the proceeding and (4) where the public interest lies. Apple expects its appeal to take at least a year to be resolved. On Wednesday, the US Court of Appeals for the Federal Circuit denied Apple’s request that an import ban on the smartwatches be lifted for the duration of Apple’s appeal of the ruling that blocked the watches. Although the watches will be less capable than watches of the same model sold before today, Apple is selling the pared-down watches at the same prices as before. (2020).Starting today, if you buy an Apple Watch Series 9 or Watch Ultra 2 it won’t be able to tell you your blood oxygen levels, a feature that Apple heavily touted when first introducing the capability in 2020. Racial bias in pulse oximetry measurement. Pulse oximeter accuracy and limitations: FDA safety communication.Pulse oximetry screening for critical congenital heart defects.

The authors concluded that more research is needed to understand and correct this racial bias. Tests like these were developed without considering a diversity of skin tones. Researchers found that among Black patients, there were three times as many cases of pulse oximetry tests failing to detect occult hypoxemia when blood gas measurements did so. Various factors can affect readings, including a person’s skin tone.Ī 2020 report compared the accuracy of pulse oximetry tests and blood gas measurements in detecting hypoxemia in Black and white patients. A level of 92 percent or lower can indicate potential hypoxemia, which is a seriously low level of oxygen in the blood. But repeated or consistent instances of lowered oxygen saturation levels may be damaging.Īn oxygen saturation level of 95 percent is considered typical for most healthy people. Having an oxygen saturation temporarily below this level may not cause damage. This is the oxygen saturation level needed to keep your cells healthy. The American Thoracic Society says that typically, more than 89 percent of your blood should be carrying oxygen. The Food and Drug Administration (FDA) requires that prescription oximeters must provide results within an accuracy range of 4 to 6 percent. With this equipment, medical professionals can carry out the tests accurately. This is especially true when using high quality equipment found in most medical offices or hospital settings. Pulse oximetry tests are an estimation of blood oxygen levels, but they’re typically precise.
