Please read this firstThis is general information, not medical advice, and nothing here is a diagnosis. Home health devices can be wrong — a fingertip oximeter can read falsely high or low depending on circulation, nail polish, movement and skin temperature. If you feel unwell, or a reading worries you, contact your doctor or emergency services rather than re-testing until you get a number you like.

So, a few months ago I was feeling super under the weather. Like, I couldn’t even get out of bed, my nose was running like a faucet, and I had a cough that would make a donkey jealous. I was convinced I had the coronavirus, so I went to get tested.

Turns out, I didn’t have the ‘rona, but I did have a wicked case of pneumonia. My doctor prescribed me some antibiotics and told me to keep an eye on my oxygen levels. I was like “uh, how do I do that?” And that’s when she introduced me to the magical world of oximeters.

An oximeter is a little device that you clip onto your finger and it tells you what your oxygen saturation levels are. It’s super easy to use and it can give you a lot of information about your overall health. It’s especially important for people with chronic lung conditions, like COPD or asthma, to keep an eye on their oxygen levels.

Anyways, I went out and got myself a Zacurate oximeter and it’s been a game changer. I’ve been able to keep tabs on my oxygen levels and make sure I’m not getting too sick. But, with so many options on the market, how do you know which one to choose?

Well, that’s where I come in. So, let’s get started!

The Top Zacurate Oximeters

Here are the top 3 Zacurate oximeters.

1. Zacurate 500DL Fingertip Pulse Oximeter

This bad boy is the top of the line. It’s got all the bells and whistles and it’s super accurate. It’s also the most expensive option, but in my opinion, it’s worth it.

2. Zacurate Pro Series 500DL

This one is a close second to the 500DL. It’s got all the same features, but it’s a little cheaper. It’s still a great option.

3. Zacurate 400DL Fingertip Pulse Oximeter

This one is the budget option. It’s still a great oximeter, but it doesn’t have all the fancy features of the other two. It’s perfect for someone who just wants to keep an eye on their oxygen levels and doesn’t need all the extra stuff.

My Personal Experience

I personally use the Zacurate 500DL Fingertip Pulse Oximeter and I love it. It’s super accurate and easy to use.

I’ve also found that it’s the most reliable option out of all the ones I’ve tried. It’s a little pricey, but in my opinion, it’s worth it.

Each guide explains what the reading actually measures, what a normal range looks like, which features are worth paying for, and the point at which a device stops being useful and you need a person instead.

A device is not a diagnosis. The guides tell you what a number means, and they say plainly when it means call your doctor.
