Hopefully it will come tomorrow

Been using for over a week and love it. I wear it on my little finger for comfort as it can otherwise uncomfortably squeeze my other fingers. I hit the power switch when I go to bed, and simply remove the sensor upon waking and it turns off after a few seconds. Use it to quantify my CPAP settings and it provides very helpful insights when used with OSCAR. No data gaps, pulls right in to OSCAR from O2 Insight Pro. I
like that it has a 4 day memory and measure once every two seconds, very detailed. Easy peazy. I highly recommend it.

I bought the Checkme O2 after noticing some drops during shorter recordings of night time SPO2 with another device (Oxyfit) . After corresponding with the manufacturer they suggested further investigation with the Checkme O2. After I received it, I used for over a week and was able to determine that I indeed suffered from sleep apnea, as there were many and very deep SPO2 drop event.

I went to see a renowned pneumologist who after seeing the Checkme O2 graphs on the excellent VHealth App and extensive report generated and emailed to him, prescribed an overnight test (polysomnography) at the hospital which came back with a a diagnosis of severe OSA (obstructive sleep apnea) . The number of events and other data recorded was nearly identical to the Checkme O2 Unit. As the events were so many (>25 per hour) and deep (SPO2 down to mid 70s) and after examining my throat, the doctor said other modes of treatment Mandibular Advance devices, surgery, etc) were not advised . Also, for this reason I could not use the otherwise excellent audio and vibrational alarm feature of the Checkme O2, so he concluded the best option in my case was getting a C/APAP.

After purchasing a C/APAP (as I travel got a very small/light unit) and seeing good results I still use the Checkme O2 to compare the recorded data of both devices. In addition, the software that is used with the Checkme O2 gives me long term information and graphs that is not available from the CPAP/APAP machine software. I find the Checkme 02 unit a perfect compliment to my travel CPAP for the additional information it gives me. The software on the phone displays historical information for very long periods and online backup is avilable as well but have not used. The finger sensor is working out fine for me as I slide it on/off from my index finger carefully. If it were to break I see there are replacements right here for a reasonable price. Very happy to have made this purchase and continue to use it daily.
