Review on EMAY Sleep Oxygen Monitor: Track Blood Oxygen Saturation & Heart Rate with App for iPhone & Android, Professional Report & 40-hour Memory by Adam Radford

Emay Sleep Oxygen Monitor - Great Price! This is the first oxygen meter I've ever bought and I was specifically looking for one that not only reads information but also records it throughout the night along with my heart rate. This fit the bill and was reasonably priced. The monitor was very easy to set up after downloading the app. I love the fact that I can just wirelessly sync it straight to my phone in the morning for easy viewing, and you can even personalize your oxygen thresholds and heart rates. Viewing the data only requires a few taps on my phone to transfer it and from there I can download it straight to my laptop or email it to my cardiologist if needed. I like that it records constantly, not just at regular intervals, so you can always see the correlation between heart rate oxygen readings. At first I was worried because I have very thin fingers so I wasn't sure if it would stay. There was no need for my apprehensions as he holds tight but gently all night. The hinge can also easily be extended for thumbs so even my husband could use it if needed. While I'm mostly sleeping, it's also handy during the day to check my oxygen levels and heart rate if needed. The fact that he writes it down means I don't have to try to memorize the numbers or stop to write them down somewhere. It's all saved for me. The monitor came with batteries and they lasted about 3-4 nights. I plan to switch to rechargeable batteries for more permanent use.
