OxyKnight® Watch Lite | Adult | Smart Sleep Oximeter

It is accurate for the test now. But I'm still trying to get it to work on overnight test. I am doing somthing wrong but I haven't figured it out yet. I think your instructions need a little more detail. I will try a few more nights to get it right before I give up.

The app and watch don't work. We tried several times it will only stay on for around 20 min. We tried different phone and charing it several times. Now it reads that my pulse is 400000 beats per minute. I think its broken.

The large, bulky finger probe catches on linens. I was doing a continuous monitoring and the “feed” was lost for a couple hours during the night, so lost the data for the middle sleep hours, until I repositioned the probe.
