Can My Apple Watch Measure Blood Oxygen Levels?

Are you curious about whether or not your Apple Watch can measure your blood oxygen levels? If so, you’re not alone. As the Apple Watch continues to evolve, more people are wondering if it can provide this vital health information. In this article, we’ll discuss everything you need to know about measuring blood oxygen levels with your Apple Watch.

The Basics of Blood Oxygen Levels

Before we dive into how the Apple Watch can measure blood oxygen levels, let’s first understand what this measure entails. Blood oxygen levels represent the amount of oxygen present in your blood. A healthy adult typically has a blood oxygen level of 95 to 100 percent. Below 90 percent indicates a potential health issue and should be addressed with a medical professional.

How the Apple Watch Measures Blood Oxygen Levels

With the release of the Apple Watch Series 6 and watchOS 7, the device now includes a Blood Oxygen app. This app uses the built-in sensors in the watch to measure the saturation of oxygen in your blood. The sensors work by shining both red and infrared light onto your wrist and then measuring the amount of light that’s absorbed. This information is then used to calculate your blood oxygen levels.

How to Use the Blood Oxygen App

Using the Blood Oxygen app is straightforward. Go to the app on your Apple Watch and follow these steps:

  1. Make sure your watch is snugly on your wrist and in the correct position.
  2. Stay still while the app takes the measurement. The process takes about 15 seconds.
  3. After the reading is complete, you’ll see your blood oxygen saturation percentage on your watch screen.

Limitations of Blood Oxygen Measurements with the Apple Watch

While the Apple Watch can provide valuable information about your blood oxygen levels, it should be noted that its readings aren’t as precise as those from a medical device. Furthermore, factors such as temperature, altitude, and skin perfusion can all impact blood oxygen readings.

Additionally, the Blood Oxygen app on the Apple Watch is intended for informational purposes only and shouldn’t be used to diagnose or treat health conditions. If you’re concerned about your blood oxygen levels or have a pre-existing medical condition, consult with your healthcare provider.

Concluding Thoughts on Measuring Blood Oxygen Levels with the Apple Watch

In conclusion, the Apple Watch can measure blood oxygen levels, but its readings should be taken as informational only. Furthermore, if you have concerns about your health, it’s always best to seek the advice of a medical professional.
