IMDK Finger Pulse Oximeter

The IMDK finger pulse oximeter uses the latest oxygen sensor technology to accurately determine the level of oxygen in blood (SpO2) in 8 seconds. The measurement range is 70% - 99% with ±2% accuracy and ±1% of resolution. IMDK finger pulse oximeter fits all finger sizes and provides 6,000 spot checks. It is easy to operate with only one button and comes with a lanyard for easy carrying. An alarm beeps to indicate oxygen level and heart rate. To save power, it automatically powers off after 8 seconds.

Sleep Monitor

Perfusion Index (PI) will improve the reliability of the readings dramatically. The PI conveniently informs you of the strength of your pulse. The sleep monitoring function can keep the data record for 8 hours and it will start analyze after monitoring for more than 2 hours.

I used one of these that a friend had and it worked OK. The one I bought consistently says "finger out" when my finger is inserted. I can't find a way to make it read my finger. The directions are very minimal and there seem to be many settings that one could change if we knew how. Manufactured in china and there are some problems with translation into English.

We are sorry this did not work for you. It sounds like you may have a defective item. Please contact us so we can rectify this for you!

This device works as described, though I do not know how it could be used for sleep monitoring. It beeps when oxygen is lower than 93%. For me, with hands that are usually cold, it takes a while for it to register that my oxygen is actually above 93%. I think the beep notification can be turned off, but I tried following the minimal documentation that comes with the device and couldn't get the beeping to stop. If you don't have issues with circulation in your hands as I do, this might be fine for you.
