REM Sleep - Neojettero - 05-24-2019
Does OSCAR provide information on REM sleep? Basically, does it show how long I'm in deep REM sleep?
Thank you,
Rob

Sorry no. OSCAR reports data from CPAP and Pulse Oximeters. It has no signals from which to determine sleep state.

Thanks for the reply. Do you know of anything that I can use?

Some use a sleep tracker like FitBit and other brands. Google it!
They are usually worn on your wrist while sleeping. You pair the tracker with an app, and it can show a graph with the different sleep stages.
These are not compatible with OSCAR, and not really sure of the accuracy of these devices.
Mabye someone else here uses one.

I have occasionally compared the sleep stages reported by my FitBit Charge HR with the Minute Ventilation reported by OSCAR, and I see some correlation with a very ragged spiky MV. I'm not sure how reliable that might be, though.

REM sleep is difficult to accurately detect, even with a sleep EEG. That is why a PSG should always involve EOG electrodes for eye movement. Brain waves during REM are very similar to those when awake and breathing and heart rates are irregular since they depend on the dream's content.
I have an under mattress sensor that regularly detects REM phases when I know I was half awake and dreaming consciously. So any non-PSG REM detection has to be taken with a grain of salt. But data from devices that try to detect sleep architecture from limb movements alone (FitBit or other bracelets) should probably be taken with a rock of salt.
Also, CPAP therapy might modulate the signals that these devices were engineered to use (i.e. breathing patterns).There are EEG sleep trackers and some even claim to track eye movement. For a while I was interested in the Dreem headband. There is a clinical study comparing it to PSG but then there is also one for my sleep tracker ...

Hi, You can use Oura ring for sleep tracking, it is pretty cool, somewhat pricey. There is an app for your phone. Here is a link to Oura data vs polysomnography data from a sleep study.

I have been a biofeedback enthusiast for many years and I have been watching the industry as it matures. The only means of determining REM sleep reliably that I am aware of is by direct measurement of the brainwave state. All others are indirect methods that measure body movement, heart rate, respiration and others, and then assume by circumstantial evidence a person is asleep. OK don't get me wrong a number of these devices do work fairly well for what they are. But, Getting good brainwave information up until recently has been a task best achieved in the lab under controlled conditions.
Not any more, check out Dreem 2 Just Google it and it will pop right up, and yes that is the right spelling.
Basically I am on the waiting list for this one, its available in France where it was developed and will be available in the US soon. I will be using this one in conjunction with my CPAP machine. If I can get more than two and a half hours of sleep in a night I am willing to try just about anything, at least once!

I was looking at the Fitbit as a cheap possibility to detect some sleep patterns like deep sleep times and maybe light sleep. The literature that is in the Fitbit ads sounds very professional.

Q: Do you have any experience with the Fitbit products and would you say they are capable of doing any type of sleep tracking?
Q: Just for a laugh, what's the price tag on the Dreem 2. Looks like in the thousands???

Hay 3rdMarDiv, Thanks for your comments!
It got me interested in checking out the Fitbit Smart Watch technology again. I can't say that I have personal experience with Fitbit, but if you do 2 searches it will answer your questions.
First search the biggest on line retailer you can think of for ( Fitbit Versa Smart Watch ) just copy and paste without the brackets and read the Customer Reviews, this is not an endorsement of a particular retailer but instead a resource to get informational reviews directly from the end user who have used the device.
Look for one that has 5,000 or more reviews, note the ratios of satisfied customers to not so satisfied, and why! Pay particular attention to the not so satisfied, that alone reveals a lot!
The other search to do is ( Fitbit wiki ) this is another resource that is quite illuminating!
I haven't been able to confirm the actual price of the Dreem 2 but I have heard rumors that it is under $500.
The ( Dreem 2 ) is only used as a sleep aid by directly monitoring your brain wave state. Do A Google search and take a look.
