Pulse oximeters are devices for measuring the pulse and oxygen content in the blood.
They can be used to determine the pathologies of the respiratory and cardiovascular systems. It will be useful for athletes and people who monitor their health after a myocardial infarction or stroke.
The main thing is to choose the most accurate pulse oximeter that will correctly display the received data.
Below I made the rating that will help you choose the most accurate pulse oximeter for home use.

Which is The Most Accurate Pulse Oximeter Nowadays?
Currently, various pulse oximeters for measuring saturation have appeared on the market.
Usually, accurate Pulse Oximeters provide data on the content of oxygen in the blood as early as 10 seconds after the start of the measurement. This criterion is also especially important if the pulse oximeter will be used on young children.
When you want to get an accurate pulse oximeter, it is important to pay attention to the fact that pulse oximeters for children and adults are different in size. And it is important that the device fits in size only then it will be accurate.
If a child measures the level of oxygen in the blood with an adult device, or vice versa, then the indicator may not be accurate.
The quality of the device itself also plays an important role – it is better to choose well-known brands and check documents.
In My opinion and from my experience, the Wellue O2 ring is the best and the most accurate pulse oximeter.
First of all, I liked the fast connection of the ring to the application. After Switching Bluetooth on my smartphone the application was connected to the device automatically.
The ring appears under Bluetooth scanners as “O2 Ring”.The application is very basic, but I like that it is stable, and does not cause any connection problems or even crashes. Setting up and using the pulse oximeter is easy.
From the first look the ring looks very massive but after you put it on your finger you understand that it is compact and light, the ring is very comfortable to the skin because it is made from silicone and it is not slippery and nice to hold.
What I liked the most is that the data will automatically upload as soon as you are out on the ring so it means that it is not needed to connect the device to your application every single day.
The ring is very easy to use because of the fast speed of measurement of pulse rate, blood oxygen saturation level.
It has a bright display with a data display where you can see all the numbers clearly, but it only shows a limited amount of information. It shows the time, heart rate, Sp02, battery level .The battery life lasts for 10- 12 hours which is OK.
There is 1 tiny micro-USB port for charging , which is hidden behind a rubberized flap.
The O2 Ring responds to changes in oxygen levels with a vibration that helps wake the wearer to change their position to a more comfortable position or to breathe and fall asleep again.
Are Cheap Pulse Oximeters Accurate?
Since a pulse oximeter is an important medical device, this purchase is not worth saving.
Preference should be given to products of reputable and well-known brands.
It is also important for what purposes the pulse oximeter will be used. If it is planned to be used only to measure the percentage of oxygen in the blood and the pulse rate, the simplest and cheapest model will be sufficient.
When choosing a device for home use, you should be guided by whether it has the appropriate registration certificate.
Reliable saturation indicators are guaranteed to be shown by a medical device. Non-certified products should not be trusted, they can provide the user with false information and mislead the person.
For example, he/she will not seek help when necessary, or, conversely, the patient may begin to panic unreasonably and require hospitalization.
