## Description

EMAY Sleep Pulse Oximeter with Built-in Recording Capability | Record Continuous Blood Oxygen Levels & Pulse Rate Overnight | Provides Sleep Report & Raw Data : desertcart.co.uk: Health & Personal Care

Review: Accurate, cheap and very easy to use. - Initially cynical about this gadgets accuracy and precision I was pleasantly very surprised at both. I used it for 4 nights initially to find out if it was likely I had sleep apnoea sleeping on my front. Recording both my oxygen levels and my heart rate throughout the night. A low heart rate whilst asleep was a question that also needed answering so it also solved that issue. Clear concise instructions, very easy to use, 2 sets of batteries and ability to transfer data to the app on your phone or laptop for summary reading and transference to print if needed. The unit comfortably stayed on my finger all night. All in all a great little unit and very happy with my purchase. Would highly recommend.
Review: can do the job - I wore this on one hand and an NHS take-home sleep study oximeter on the other (£1000 device). While the nhs did not give me the full data, the headline ODI and low SP02 point was very similar enough to feel like it can do the job. The device is easy to use and data summary very useful for showing you what is going on and talking to a GP / respiratory nurse. I also found it useful to experiment with diet and sleeping position effects on sleep breathing. The low SP02 alarm is effective and reassuring if to avoid scary 02 drops if things are difficult. The app and printout summaries are very useful. It works with normal AAA rechargeable batteries which I always prefer compared to more expensive models. I am a 3xl and find it comfortable enough to wear every night with just the clip and no strapping. Serves as a useful torch. Screen rotation is also nice feature. Price is good compared to others. It is also regularly put on offer. Review is for deal price <£40.

## Questions & Answers

**Q: How do I clear the memory once it is full?  I have uploaded the data to my phone already.**
A: Once downloaded there is a "dustbin" symbol in the top right of your phone screen to delete the data from the Oximeter

**Q: Can results be put on laptop? I have no mobile phone. Also can it be used as a one off for quick oxygen test?**
A: No, as per the information in the description, it's only compatible with Android or iPhone. As for a "quick oxygen test" why would you do that? You would want a fair bit of data over time to average out the readings, because your SPO2 does fluctuate. A quick reading might give unnecessary concern, if it's dipped to say 92% briefly but gone back up to say 98% - this info was relayed to me by NHS 111. You can just as easily buy a cheap oximeter and get the readings from the actual device then write them down. Always work with your healthcare professional. Hope this helps.

**Q: How well does this attach to your finger during sleep?**
A: It has rubber inside and fits and stays on finger during sleep. It stays very well and doesn't hurt.

**Q: Only getting 6 hours recording on one set of batteries, 8 hours on another set. Says 24 hr Continuous recording? I must have a faulty unit.**
A: I managed to get three 8 hour recordings from one set of batteries.

### ⭐⭐⭐⭐⭐ Excellent pulse oximeter at an affordable price.
*by C***A on 29 December 2025*

This is a brilliant piece of kit for monitoring blood oxygen saturation and pulse rate during sleep. In essential combination with the app I am able to provide health professionals with different data formats including summary sheets in PDF format and to which you can add your own relevant remarks. I now understand why some days I feel so tired and others are fine. This is necessary monitoring and very cost effective. The device is very affordable and I am pleased at last I can do what the NHS can't. Thanks to EMAY! My best purchase this year.
