## Blood Oxygen Description
With the Blood Oxygen app on Apple Watch Series 6 or later*, you can measure the blood oxygen saturation levels directly from your wrist. Using the blood oxygen sensor on Apple Watch, the Blood Oxygen app can help you assess oxygen levels in your blood and get insights into how well your body is absorbing oxygen and overall wellness. 

Features

• Allows you to take on-demand blood oxygen measurements.

• Performs periodic background measurements throughout the day and overnight if you wear your Apple Watch to sleep.

• Stores all measurements in the Health app on iPhone, with the ability to filter and view measurements taken while asleep or in a high-elevation environment.

*For models of Apple Watch purchased in the United States on or after January 18, 2024 with part numbers ending in LW/A, the Blood Oxygen data analysis is performed on iPhone, and results can be viewed in the Health app.

## Blood Oxygen Reviews in United States

### *---- "Why this app doesn’t work on Apple Watch serie 4"
Why
-- Quiquecardona, 2022-03-12

### *---- "Can’t get on my watch"
This is frustrating.  How do I get this on my watch?  I have followed all the instructions.
-- MangoMpls, 2022-03-07

### *---- "18+"
Anyone with a watch should be able to access HEALTH features. Blood oxygen levels are not inappropriate for anyone to see.
-- LUPLily, 2022-02-21

### *---- "Why???"
I have an new apple SE watch and can’t have this app?!?! Make it available it could be really helpful for people who have asthma
-- hate apple currently, 2022-02-08

### ***-- "Needs a low oxy notification!!!!"
Major oversight? Why doesn’t this offer a low blood oxygen notification? Like how we get an AFIB or high heart rate notification if we have an Apple Watch? It would really help with COVID patients who are told they don’t need to go to the hospital until they reach a certain threshold.
-- Reads in bed., 2022-01-27

### ***** "Oxygen"
It should have heart and pulse
-- Aries Ferrer, 2021-12-24

### *---- "Unable to download the app"
Not able to download the app tho my account is a US account and staying in a region eligible to download the app. 
Anyone could help? 

Hence, my brother downloaded it but I couldn’t!!
-- Riyami86, 2021-12-10

### *---- "Blood oxygen"
Doesn’t download on my Apple Watch or phone. Still struggling.
-- Bhushaiah, 2021-12-08

### *---- "Inactive blood oxygen"
Hello, why the Blood Oxygen Program and the ECG program do not work in the Watch Series 6 in Iran. We, who provide watches with so much effort, should not be able to use its facilities. It is our right to use technologies.
-- م م ق !!!, 2021-11-14

### *---- "Bad"
Doesn’t work on Siris 3
-- sad man10, 2021-10-28
