Best Pulse Oximeter Reviews and Comparisons 2018: Home Oximeters

To find the best pulse oximeter on the market, it’s important to know the key features to look for. Fingertip oximeters you can use at home usually cost no more than $25, but they can easily cost hundreds of dollars, so it’s important to only pay for what you need.

So which is the best oximeter for you?

In this guide, we’ll focus on home oximeters that attach to your fingertip. They’ve proven themselves to be a quick, effective, and non-invasive way of measuring blood oxygen saturation (Sp02), pulse rate, and even pulse strength and fluctuation (plethysmograph) with some devices.

You’ll find expert reviews for some of the best pulse oximeters from global brands that are based right here in the USA. We’ll also walk you through how to achieve the most accurate readings with pulse oximetry and how to monitor blood oxygen levels.

What is Pulse Oximetry?

Pulse oximetry is the process of monitoring blood oxygen saturation non-invasively using infrared light, as opposed to through a blood sample. Accurate readings can usually be achieved in less than 10 seconds, using a finger pulse oximeter.

The light looks for changes in blood volume in the skin, and most of the top oximeters also provide feedback for your pulse rate. Due to the size of the clip on a finger pulse ox, a device for adults won’t always be suitable for young children. That’s why, if you plan on measuring a young child’s Sp02 levels (ages 2+), we recommend buying an oximeter that’s specifically designed for smaller fingers.

One of the best on the market is the Zacurate Children, with hundreds of highly rated reviews on Amazon. If you need to track the Sp02 level of an infant younger than 2 years, we recommend seeking advice from your doctor.
