An update on Blood Oxygen for Apple Watch in the U.S. has sparked excitement among tech enthusiasts and health-conscious users alike. Imagine strapping on your Apple Watch, glancing at your wrist, and knowing how well your body is oxygenating itself—all with a few taps. That’s the kind of innovation Apple has been chasing since it first introduced the Blood Oxygen feature. But, as many of you know, this feature hit a snag in the U.S. due to a legal tussle. Now, with a fresh software update, Apple is bringing it back in a redesigned form. So, what’s the deal? Why was it gone, and how’s it making a comeback? Let’s dive into the details of this game-changing update and what it means for you.
The Blood Oxygen Feature: A Quick Rewind
An Update on Blood Oxygen for Apple Watch in the U.S. : Before we get into the nitty-gritty of an update on Blood Oxygen for Apple Watch in the U.S., let’s take a step back. The Blood Oxygen app, first introduced with the Apple Watch Series 6 in 2020, was a big deal. It allowed users to measure their blood oxygen saturation (SpO2) levels right from their wrist. Whether you were hiking at high altitudes or just curious about your respiratory health, this feature gave you real-time insights. It was like having a mini health lab on your wrist—pretty cool, right?
But here’s where things got messy. A legal dispute with medical device company Masimo threw a wrench into the works. Masimo claimed Apple’s Blood Oxygen feature infringed on its patents, leading to a U.S. International Trade Commission (ITC) ruling that banned the sale of Apple Watches with this feature in the U.S. As a result, newer models like the Apple Watch Series 9 and Ultra 2 were sold without it. Talk about a plot twist! For a while, it seemed like U.S. users were stuck without this handy tool. But Apple, being Apple, didn’t sit idly by.
An Update on Blood Oxygen for Apple Watch in the U.S.: What’s New?
An Update on Blood Oxygen for Apple Watch in the U.S. : Fast forward to August 2025, and an update on Blood Oxygen for Apple Watch in the U.S. has changed the game. Apple announced a redesigned Blood Oxygen feature for select Apple Watch models—specifically the Series 9, Series 10, and Ultra 2. This update, enabled by a recent U.S. Customs ruling, is rolling out through software updates to iOS 18.6.1 and watchOS 11.6.1. So, what’s different this time? Instead of processing the data directly on the watch, the Blood Oxygen app now sends sensor data to your paired iPhone, where it’s calculated and displayed in the Health app’s Respiratory section.
Think of it like this: your Apple Watch is the data collector, and your iPhone is the brain crunching the numbers. This workaround cleverly sidesteps the patent issue while still delivering the insights users love. It’s like Apple found a backdoor to keep the party going without breaking any rules. If you’re rocking one of these compatible watches in the U.S. and didn’t have the Blood Oxygen feature before, this update is your ticket to getting it back.
How to Access the Redesigned Feature
So, how do you get in on an update on Blood Oxygen for Apple Watch in the U.S.? It’s pretty straightforward. First, make sure your iPhone is updated to iOS 18.6.1 and your Apple Watch is running watchOS 11.6.1. Once you’ve got that sorted, your watch will automatically download the necessary wireless assets for the new Blood Oxygen feature. Be patient, though—this download might take up to 24 hours. To kick things off, open the Health app on your iPhone or the ECG app on your watch. From there, you can start taking measurements or enable background monitoring to keep tabs on your SpO2 levels throughout the day.
It’s worth noting that this update only applies to U.S. users with newer Apple Watch models that didn’t originally ship with the Blood Oxygen feature. If you bought your watch outside the U.S. or have an older model with the original feature, nothing changes for you. Apple’s made it clear that those devices are unaffected, so you can keep using them as is.
Why the Change? The Masimo Dispute Explained
An Update on Blood Oxygen for Apple Watch in the U.S. : To understand why an update on Blood Oxygen for Apple Watch in the U.S. was even necessary, we need to talk about the Masimo drama. Masimo, a company known for its medical-grade pulse oximeters, accused Apple of stealing its technology and even poaching employees who helped develop it. In 2023, the ITC sided with Masimo, ruling that Apple’s Blood Oxygen feature infringed on their patents. This led to a temporary ban on selling certain Apple Watch models in the U.S., forcing Apple to disable the feature on new devices.
It was a classic David vs. Goliath story—except this time, Goliath (Apple) had to rethink its strategy. By moving the data processing to the iPhone, Apple found a way to comply with the ruling while still offering the feature. It’s like rewriting the rules of the game to keep playing. This update shows Apple’s knack for innovation, even when the odds are stacked against them. And for users, it means you don’t have to miss out on a feature that’s become a staple for health-conscious Apple Watch owners.
What Does This Mean for Your Health?
So, why should you care about an update on Blood Oxygen for Apple Watch in the U.S.? Blood oxygen monitoring isn’t just a fancy gimmick—it’s a window into your respiratory health. Your SpO2 levels indicate how well oxygen is being carried from your lungs to the rest of your body. Low levels could hint at issues like sleep apnea, lung conditions, or even just the effects of high-altitude activities. For fitness buffs, it’s a great way to gauge how your body’s performing during intense workouts.
With the redesigned feature, you can still take on-demand measurements or let the watch monitor your levels in the background. The data syncs seamlessly to the Health app, where you can track trends over time. It’s like having a personal health coach that never sleeps. Plus, Apple’s ecosystem ties this data into other features like irregular rhythm notifications, ECG readings, and sleep tracking, giving you a holistic view of your well-being.
The Bigger Picture: Apple’s Health Ecosystem

The Apple Watch has evolved from a simple fitness tracker to a powerhouse of health tools. With features like Fall Detection, Sleep Apnea Notifications, and the Mindfulness app, it’s clear Apple’s aiming to empower users to take charge of their health. The Blood Oxygen feature, even in its redesigned form, fits perfectly into this vision.
But let’s be real—Apple’s not doing this just out of the goodness of its heart. Health features are a major selling point for the Apple Watch, setting it apart from competitors like Fitbit or Garmin. By bringing back the Blood Oxygen feature, Apple’s reinforcing its position as a leader in wearable tech.

What’s Next for Apple Watch?

For now, though, this update is a win for U.S. users who’ve been missing out.
If you’re an Apple Watch fan, this is a reminder of how dynamic the device is. Software updates can breathe new life into your watch, adding features you didn’t even know you needed.

Tips for Making the Most of the Blood Oxygen Feature
An Update on Blood Oxygen for Apple Watch in the U.S. : Ready to dive into an update on Blood Oxygen for Apple Watch in the U.S.? Here are a few tips to get the most out of it:
- Stay Still During Measurements: For accurate readings, keep your wrist steady and flat. Think of it like trying to balance a cup of coffee without spilling.
- Enable Background Monitoring: Let your watch track your SpO2 levels throughout the day for a better picture of your health trends.
- Check the Health App Regularly: The Respiratory section is your go-to spot for reviewing your data. It’s like flipping through a health journal tailored just for you.
- Combine with Other Features: Pair Blood Oxygen data with ECG or sleep tracking for a fuller understanding of your body’s signals.
By incorporating these habits, you’ll turn your Apple Watch into a powerful ally for staying on top of your health.
Addressing Concerns: Is the Redesigned Feature as Good?
Some of you might be wondering: does this redesigned Blood Oxygen feature stack up to the original? It’s a fair question. The main difference is that the processing now happens on your iPhone instead of the watch. This might mean slightly slower results, but the accuracy should remain solid since the same sensors are collecting the data. Apple’s known for its rigorous testing, so you can trust they’ve fine-tuned this workaround to deliver reliable insights.
That said, it’s unclear if the new setup supports instant readings as seamlessly as the original. Some sources suggest you might need to dig into the Health app to see results, which could feel less immediate. Still, the fact that Apple’s brought this feature back at all is a win. It’s like getting your favorite dish back on the menu, even if the recipe’s been tweaked a bit.
