IMDK Finger Pulse Oximeter

The IMDK finger pulse oximeter uses the latest oxygen sensor technology to accurately determine the level of oxygen in the 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

The 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 to analyze after monitoring for more than 2 hours.

Finger Pulse Oximeter
When my Mom was released from hospital with a prescription for oxygen therapy we were all a little overwhelmed. We had to get a 5l stationary home oxygen concentrator and tubing before she could be released. All we had was a prescription but no experience with oxygen at all. Our fears were put to rest when we called Cpapman. The respiratory therapist we spoke to was so kind and just full of information for us. We learned about the concentrator, the bubble bottle and the tubing. My Mom needed oxygen therapy for exertional activity. The tricky part was she really did not look like her oxygen levels were low when they were. Cpapman encouraged us to get a Finger Pulse Oximeter to help us understand Mom's oxygen levels better. This was the best advice. Everything has been great for Mom at home with her own oxygen equipment. Mom will put the oximeter on her finger when she is at sitting still in her favourite chair and see her SP02 levels are over 90. Then when she stands up the drop to 87 right away. With this knowledge, she knows to put on her oxygen before she stands up. This keeps her oxygen levels at 90. Mom is super confident now because of the finger pulse oximeter. Thank you Cpapman.

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.
Pls update me of 1000pcs of pulsoximetre
