## Description

Product description EMAY EMO-90 Sleep Pulse Oximeter gives you the extraordinarily informative & valuable overnight report.

Review: So I don't usually love pulse oximeters, but I love this one. - I've had a few pulse oximeters, but this one supersedes them all. It does the job, and it's not a hassle at all. Some things that I really like: * Fast readings (and seemingly accurate readings, too) * Clear and easy to read * Long readings (I can wear it overnight easily and still have battery leftover the next couple days.) * Graphs show what's been logged. These can also be sent as PDFs to your email and to your doctor. * Personalization (I think it came with a 94% SPO2 lower reading, but I set mine to 90% minimum for SP02 to match what my doctor's office uses.) * Easy to charge (I just plug it into my computer, and it charges.) * Easy to upload what it logs. Just click "connect" in the app, and it does the rest. The only things I wish they'd do different is make it a little more comfortable. It's great for spot checks, but after a while, I'm ready to take a break from wearing it (but then again, how much can they actually change to make these more comfortable without compromising the accuracy?) Also, after that, after a couple minutes, the "recording" message comes on. I guess I'm nosy in that I want to see what's being recorded. Otherwise, it's my dream pulse oximeter. :)
Review: Rechargeable Oxygen Monitor - Arrived promptly and I began the start up. The instructions were easy to follow. I’m older and not tech savvy, but was able to hook up to my iPad Bluetooth. The oximeter easily stays on my finger overnight. I did not want to tape around my finger so I used a soft ankle sock over my hand for overnight recording to insure the monitor did not slide off. In the mornings I simply turn on my oximeter and open my iPad. I click on my downloaded EMAY App. The App screen is easy to understand and prominently gives the option to Edit or Connect. The graphs are very easy to understand. There is even a place to make remarks on recorded readings of the SaO2 and pulse rate. The recording is continuous minute by minute. This monitor gives a great picture of what happens with SaO2 and Pulse rate anytime of the day, but especially overnight. Plus, no batteries are needed. Simply plug in to recharge. I am very pleased with my purchase. In addition EMAY customer service reached out to me to insure everything was working as expected and to ask if I had any problems.

## Features

## Questions & Answers

**Q: Why did the alarm just wake me, even though the data shows oxygen and heart rate were never out of range?**
A: I don't use the alarm option. May have been a sudden drop that you can barely see on the printout. Enlarge the printout and also check the alarm settings as well.

**Q: i am looking at emayltd official website, they 've just posted two types of cheaper oxymeter, isn't it weird? None of them look like this...**
A: The do have a cheaper version. Go for this one

**Q: Has anyone used this device during the day for continuous recording?**
A: If you are active, wearing it all day wouldn't be practical. I've used it while riding my bicycle (to see if that would put my heart in a bad way - it would, dang it). But it's clumsy to wear, and best to tape it on if doing anything even semi-active. I tape it on at night as well.

**Q: Does it record spot readings to history? Or does it only save continuous recordings?**
A: It only records when "Record" is turned on.  It does not record spot readings if "Record" is turned off.   The memory will record as many segments as you want, short or long, up to a cumulative total of 72 hours.

### ⭐⭐⭐⭐ Best unit I have found so far
*by R***G on June 7, 2022*

I have a garmin vivosport watch, another pulse oximeter that I got off of Amazon and then this emay unit. The Emay is significantly better than the other devices for my uses which are mainly tracking heart rate and blood oxygen. The Emay gives the most consistent results and records all data up to 72 hours. The graphs created by the phone app are very informative and it is easy to access heart rate and blood oxygen values. The app prepares an excellent summary which can be sent to your doctor. Battery life is good as well. It is simple to delete data sets, turn recording on and off, and synch the unit to the app.
