Nonin makes a GO2 oximeter that is just as accurate as my doctor's more expensive Nonin. Got it for $79 with free shipping, on the web.

I have used the CMS 50e $149, the Walgreens branded $49 from drive medical, and currently am using the GO2 from nonin $99. The Nonin has given me the most consistent readings, followed by the cheap chinese CMS 50 wrist oximeter. The Walgreens was always about 4 or 5 points higher than others. The CMS 50 came with software and the ability to upload stats to computer and store them. But my experience was that the software is flaky and unreliable.
Yes I am obsessed with my ox stats, I check about 25 times a day. I keep a database of my stats ox, pulse, BP, temp, weight, before and after exercise as well as the stats about the exercise, duration, speed, incline or resistance. You can do this on a sheet of paper or just in columns in word or excel. It lets you see your progress, tells you if you might have a flareup or infection. Gives your doctors a clue, if your doctor doesn't seem interested then find a new doctor. (personal opinion)
I find that when I feel SOB it is good to look at my O2 stats and be reassured. Lowers anxiety and lets things get back to normal more quickly with some pursed lip or diaphramtic breathing. Most imsurance won't pay but having the info from an oximeter is well worth it. Even the cheap ones will usually give you a consistent reading that you can adjust for. But the cheaper ones do have a little trouble distinguishing O2 from CO2 so may read a bit different.

FEV1 67, O2 2 LM / 3LM to exercise etc... also had heart attack N double bypass, enlarged lungs and Hiatle Hernia.

George, most people ARE obsessed with their sat levels when they first get their pulse oximeters but then the "newness" and the obsession wears off and they go about living their daily lives. Why are you so obsessed with yours, still? I guess if that's all you have to do during the day, it would keep one occupied, though, but you're only 67 so one would think you'd be out and about and shopping and living life.

I check mine seldom, and only when I am deciding if I need to call the doctor.

George - if an oximeter couldn't distinguish between O2 and CO2, wouldn't it show 100% saturation all the time?

They only measure the O2, not CO2. O2 changes the color of blood (as does CO) and they measure that.
The colour of blood varies depending on how much oxygen it contains. A pulse oximeter shines two beams of light through a finger (or earlobe etc.), one beam is red light (which you can see when a pulse oximeter is used), one is infrared light (which you don't see).

These two beams of light can let the pulse oximeter detect what colour the arterial blood is and it can then work out the oxygen saturation. However there are lots of other bits of a finger which will absorb light (such as venous blood, bone, skin, muscle etc.), so to work out the colour of the arterial blood a pulse oximeter looks for the slight change in the overall colour caused by a beat of the heart pushing arterial blood into the finger.

This change in colour is very small so pulse oximeters work best when there is a good strong pulse in the finger (etc.) the probe is on. If the signal is too low the measured oxygen saturation may not be reliable and lower than this the pulse oximeter will not be able to work.

Yes, but I do not use Canadian spelling after an American education, I just found the best source.

So, you have the meter and take the readings. What do you do with them and what is the number you used to say it is too low and call the doctor.

If your sats drop below 90, you stop what you're doing and rest awhile. There really isn't any need to call your doctor unless your sats stay continually below 90 while sitting or even walking because that would possibly indicate the need for supplemental O2. My sats have gotten, very occasionally, down to the mid 70's but that was when I was REALLY doing something strong (like moving bales of hay or other heavy work).

Forgive my ignorance. What is the difference between these oxymeters and the $30 ones you get at the drug store? It reads the same as the ones at the doctor's office do. Also, do any of you know of one that has an alarm when your saturation gets too low? When I sleep my numbers get scary--like 70. If I wake up and lean over and breathe deep I can get the numbers back up, but I'm scared I'm not going to wake up. I want to outlive my dogs. After that, I will quit worrying about it so much. This is on 4 liters of oxygen.

There are some recording pulse ox devices available under $100 that have alarms.

I suggest you talk to your doc about a BiPAP or external ventilator. One or the other might solve the problem rather than just alerting you.

Hello there,
I am Deeny and this is my first post. I am newly diagnosed with COPD, newly on oxygen. I bought an "Accurate CMS 500D" for $23.99 on Amazon. I took it to my doctor appointment yesterday and the readings matched within one point what the nurse got with her much more sophisticated machine.

This small device measures oxygen saturation and pulse rate and it has an alarm that can be set.

Late to this thread but Amazon has them for as low as $18.95. I was amazed at when I saw Dave's first post and that price.

This thread started in 2011. Prices have continued to fall.
