Manufacturers of smartwatches and bracelets can prove the effectiveness of pulse oximeters in their gadgets as much as they want. But this function will never work properly on the wrist. Blood oxygen level measurement is done through a finger and special sensors designed for this purpose. However, bracelet manufacturers deserve credit. Thanks to them, the market has seen many ready-made solutions at very affordable prices.
Digital Finger Pulse Oximeter – what it is and why you need it
A pulse oximeter is a device capable of simultaneously measuring pulse rate (PR) and blood oxygen saturation (SpO2). Both indicators can reveal diseases related to internal organs. The results obtained after measurements can be compared with reference results to identify health issues. Digital devices are in demand in medicine and everyday life.
Advantages of buying a digital finger pulse oximeter
In specialized stores that focus on selling medical equipment, dozens of pulse oximeter models are available. Without many features, devices are priced too high for the average consumer. This is the main drawback of these gadgets, which deters potential buyers. The cost of equipment can start from $50. The more well-known the brand on the market, the more expensive its medical measuring devices.
And the problem is solved by products from China. But not all. An important criterion for any medical device is measurement accuracy. If the seller does not specify it, or the indicator is above 3%, then the digital pulse oximeter is of low quality. It is not suitable even for household purposes. Because an error margin might lead the user to active self-treatment, which may not be necessary at all.
Which digital finger pulse oximeter is better
The primary task for the buyer is to completely exclude additional features of the measuring device. It is better to focus on 2 basic characteristics:
- Pulse measurement (within 25-240 beats per minute).
- Blood oxygen level measurement.
Once the accuracy of the medical device is determined, it is better to immediately look at quality certificates. Most sellers simply do not have them available. By the way, if the manufacturer claims CE certification, the purchased product should come with a copy of this document.
Additional features such as sound indication, backlight, memory in the device, wireless technologies increase the price of the device. The fewer “conveniences,” the more affordable the pulse oximeter for the buyer. A quality device costs from 20 to 50 US dollars.
It may happen that Chinese sellers list the same model at different prices. Here, you will need to study all products and find a suitable pulse oximeter by cost. If you don’t have time to search, look at the device we recommend, which has received excellent reviews from buyers.
