Apple Watch Blood Oxygen USA – iOS 18.6.1 Update
Apple Reinstates Blood Oxygen Feature on Apple Watch via software Update: A Workaround for Patent Dispute
Table of Contents
Apple has quietly reintroduced the blood oxygen measurement feature on its Apple Watch in the United States, but with a twist. This return comes after a patent dispute with Masimo, a medical technology company, which led to apple disabling the feature on new apple Watch models sold in the US. The solution? A software update that changes how the blood oxygen levels are measured.
The Masimo Patent Dispute Explained
The heart of the matter lies in a patent dispute between Apple and Masimo. Masimo claims that Apple infringed on its patents related to blood oxygen measurement technology. These technologies, developed and patented by Masimo, are used in pulse oximeters to non-invasively measure blood oxygen saturation. Such disputes can have notable consequences, perhaps leading to sales bans or significant licensing fees.
iOS 18.6.1 and watchOS 11.6.1: The Key to Reinstatement
The workaround comes in the form of the latest software updates: iOS 18.6.1 for iPhones and watchOS 11.6.1 for Apple Watches. These updates are now available for download.
iPhone: to update your iPhone, navigate to “Settings” > “General” > “Software Update.”
Apple Watch: Update your Apple Watch through the Apple Watch app on your iPhone.
Crucial Note: after installing the updates, it may take up to 24 hours for the blood oxygen function to become available. Users can potentially expedite this process by opening the Health app on their iPhone and the EKG app on their Apple Watch.
according to AppleS security update documentation, these updates do not address any published CVE entries, suggesting that they primarily focus on implementing the blood oxygen measurement workaround rather than patching security vulnerabilities. This could mean that no security gaps have been addressed, or that the resolved problems were not stored in the database.
US-Only Workaround: what You Need to Know
It’s crucial to understand that this workaround is exclusively for Apple Watch users in the United States. In other regions, the blood oxygen measurement feature remains fully functional on iOS and watchOS, as it was before the dispute. The update was published globally,but the change only affects US models.
Strategic Timing for Apple
The reintroduction of the blood oxygen measurement feature is perfectly timed for apple. With the anticipated unveiling of the Apple Watch Series 11 in September,the company can now confidently promote the full suite of health features once again. The new models are expected to incorporate the revised blood oxygen measurement technology. This allows Apple to maintain its competitive edge in the wearable health tech market.
No Changes for International Users and Older Models
For Apple Watch users outside the United States and those who own older Apple Watch models,there are no changes. These users were never affected by the patent dispute and can continue to measure their blood oxygen levels directly on their Apple Watch without any modifications.
Looking Ahead: The Future of the dispute
The Masimo patent that triggered this conflict is set to expire in August 2028.Until then, the software-based workaround for US users will remain the only way to measure blood oxygen levels using their Apple Watch. It remains to be seen if Apple and Masimo will reach a settlement before then,or if Apple will develop a wholly new,patent-free method for blood oxygen measurement.
