Apple announced the Apple Watch Series 6 during its September 15 event in 2020. The platform has matured in design and software, but Apple has pushed it forward again with new health functions and more color and band options.

Apple Watch Series 6 Features:

  • The future of health is on your wrist.
  • On your iPhone, open the Health app.
  • ECG On your wrist, Anytime, Anywhere.
  • Sleep A better day begins with a better night.
  • Fitness, We pushed it further to push you further.
  • Motivation, Inspiration for your perspiration.

Measure your blood oxygen level with a revolutionary new sensor and app. Take an ECG anytime, anywhere. See your fitness metrics at a glance with the enhanced Always-On Retina display. With Apple Watch Series 6 on your wrist, a healthier, more active, more connected life is within reach.

Your blood oxygen level is a key indicator of your overall wellness. It can help you understand how well your body is absorbing oxygen, and the amount of oxygen delivered to your body. The remarkable new sensor and app in Apple Watch Series 6 allow you to take on-demand readings of your blood oxygen as well as background readings, day and night.

New sensor. New insights. The new blood oxygen sensor is made up of four LED clusters and four photodiodes. Incorporated into the completely redesigned back crystal, this new sensor works in concert with the Blood Oxygen app to determine your blood oxygen level.

Deeply illuminating. Green, red and infrared LEDs shine light onto the blood vessels in your wrist, and photodiodes measure the amount of light reflected back. Advanced algorithms then calculate the colour of your blood, which indicates the amount of oxygen present.

Here’s what you need

Make sure that the Blood Oxygen app is available in your country or region. You will be able to see this during the setup process.

  1. Update your iPhone 6s or later to the latest version of iOS.
  2. Update your iPhone 6s or later to the latest version of iOS.
  3. The Blood Oxygen app is not available for use by people under 18 years old.

Set up the Blood Oxygen app and background readings

On your iPhone, open the Health app.

Follow the onscreen steps. If you don’t see a prompt to set up, tap the Browse tab, then tap Respiratory > Blood Oxygen > Set up Blood Oxygen.
After you complete setup, open the Blood Oxygen app on your Apple Watch to measure your blood oxygen levels.
If you still don’t see the Blood Oxygen app on your Apple Watch, you can search the App Store on your Apple Watch for Blood Oxygen and download it.

The Blood Oxygen app is installed during the setup in the Health app. If you delete the Blood oxygen app, you can install it again from the App Store on your Apple Watch if you’ve completed the Blood Oxygen app setup.

Measuring your blood oxygen levels with the Blood Oxygen app on Apple Watch Series 6
You can measure your blood oxygen levels with the Blood Oxygen app.

The Blood Oxygen app can allow you to measure the oxygen level of your blood on-demand directly from your wrist, providing you with insights into your overall wellness. Measurements taken with the Blood Oxygen app are not intended for medical use and are only designed for general fitness and wellness purposes.

The Blood Oxygen app is only available in certain countries and regions.

What is blood oxygen?

Your blood oxygen level represents the percentage of oxygen your red blood cells carry from your lungs to the rest of your body. Knowing how well your blood performs this vital task can help you understand your overall wellness.

The majority of people have a blood oxygen level of 95 – 99%. However, some people live a normal life with blood oxygen levels below 95%.

How to use the Blood Oxygen app

Make sure that you meet the below requirements and follow the steps to set up the Blood Oxygen app.

  • Make sure that your Apple Watch is snug but comfortable on your wrist.
  • Open the Blood Oxygen app on your Apple Watch.
  • Stay still, and make sure your wrist is flat with the Apple Watch facing up.
  • Tap Start, then keep your arm steady for 15 seconds.
    Wait. The measurement takes 15 seconds. At the end of the measurement, you will receive the results.
  • Tap Done.

About background measurements

The Blood Oxygen app on your Apple Watch will occasionally measure your blood oxygen levels if background measurements are on. This will usually happen when you are not moving. Depending on how active you are, the number of readings collected each day and the time between these readings will vary. Blood oxygen measurements use a bright red light that shines against your wrist, so it may be more visible in dark environments. If you find the light distracting, you can turn off background measurements.

  • Open the Settings app on your Apple Watch.
  • Tap Blood Oxygen, then turn off In Sleep Mode and In Theater Mode.
  • Blood oxygen measurements only occur during sleep if the Track Sleep with Apple Watch setting is turned on.

How the Blood Oxygen app works

In Apple Watch Series 6, the optical heart sensor has been redesigned to add blood oxygen measurement capabilities. During a blood oxygen measurement, the back crystal shines red and green LEDs and infrared light onto your wrist. Photodiodes then measure the amount of light reflected back.

View your Health information

All blood oxygen measurements, whether on-demand or in the background, are saved in the Health app on your iPhone.

  • Open the Health app.
  • Tap the Browse tab, then tap Respiratory > Blood Oxygen.
  • You can also filter and view measurements taken only while sleeping or in a high-elevation environment.

Things you should know

Blood Oxygen app measurements are not intended for medical use, including self-diagnosis or consultation with a doctor, and are only designed for general fitness and wellness purposes. If you have questions about your health, contact a medical professional.
The Blood Oxygen app is designed for users who are at least 18 years old.
Slightly lower values while sleeping are expected, and some users might experience values below 95%.

Additional factors

Even under ideal conditions, your Apple Watch may not be able to get a reliable blood oxygen measurement every time. For a small percentage of users, various factors may make it impossible to get any blood oxygen measurement. Skin perfusion (or how much blood flows through your skin) can impact measurements. Skin perfusion varies significantly from person to person and can also be impacted by the environment. If you are out in the cold, for example, the skin perfusion in your wrist might be too low for the sensor to work with the Blood Oxygen app to get a measurement.
Permanent or temporary changes to your skin, such as some tattoos, can also impact performance. The ink, pattern, and saturation of some tattoos can block light from the sensor, making it difficult for the Blood Oxygen app to get a measurement. Motion is another factor that can affect your ability to get a successful background or on-demand measurements. Certain postures, such as arms hanging by your side or fingers in a fist position will also result in unsuccessful measurements.
If your heart rate is too high (above 150 bpm) while at rest, you won’t be able to get a successful blood oxygen measurement.

ECG On your wrist, Anytime, Anywhere.

With the ECG app, Apple Watch Series 6 is capable of generating an ECG similar to a single-lead electrocardiogram. It’s a momentous achievement for a wearable device that can provide critical data for doctors and peace of mind for you.

Your finger can tell you a lot about your heart. Electrodes built into the Digital Crown and the back crystal work together with the ECG app to read your heart’s electrical signals. Simply touch the Digital Crown to generate an ECG waveform in just 30 seconds. The ECG app can indicate whether your heart rhythm shows signs of atrial fibrillation — a serious form of irregular heart rhythm — or sinus rhythm, which means your heart is beating in a normal pattern.

Sleep A better day begins with a better night.

Getting the right amount of sleep is important for good health. The new Sleep app helps you establish a regular bedtime routine and keep track of your sleep trends night after night. So you can set and achieve your personal sleep goals.

Fitness, We pushed it further to push you further.

When it comes to staying fit, knowledge is power. Get inspiration to keep moving and track your workout metrics more precisely than ever — in the water, at the gym, or out on the road. Series 6 is Apple Watch at its best. To help you be your best.

Motivation, Inspiration for your perspiration.

Day after day.Activity Sharing. Share your Activity rings with friends and family to encourage each other. Competitions. Invite friends to compete in a seven-day Activity challenge.
