okay, I am curious now… I have a sleep study in 2 months. While I struggle with daytime urgency and enuresis at night how in the world would they be able to tell if I am voiding while I am asleep versus when I am awake? I do have some control and there are many mornings where I will wake up and use my diaper so I don’t have to get right out of bed. While this is not always the case as most nights I am voiding while I am asleep and awake to an empty bladder I would hate to think that they could tell that I intentionally wet my diaper the morning of my study once I am awake. I will sometimes also use my diaper as I am falling asleep if the urgency hits me and I don’t think I’ll be able to make it if I get out of bed. Enlighten me please and thank you!
There are a myriad of sensors all over your head and body to detect brain waves, heart rate and respiration, and arm and leg movement. There is also a video camera recording you while you sleep. There are many "tells" when one voids; change in heart rate, change in respiration, and muscle contractions.
If you wet while falling asleep, it would likely be ignored as just you trying to get comfortable with all the wiring attached to you.
If you wet while asleep, it is during a NVREM (non REM) interval, and the normal tells of voiding are not there.
If you wake during the night, there will be a temporary change in brain waves, heart rate, respiration, and possibly muscle contractions if you adjust your position. If you choose to wet during this awake time, the above changes will be more marked, causing the technician to be notified, who will now be closely watching you over video and ask over the intercom if you are okay. You may think that all it takes is to relax to void, but in reality there is a lot going on.
Most sleep labs finish the study and wake you at 5AM to 6AM. The technicians want to get out of there, so they wake you up, ask if you need the restroom or if you can hold it while they remove the sensors. If you happen to wake up before the normal wake time, but enough time has passed for the study, they will ask you over the intercom if you are finished sleeping. If you say yes, they will be in momentarily to remove sensors. Either way, if you intentionally wet upon waking in the morning, the technician will be pulling out wires run through your sleep clothes past a freshly wet and warm diaper.
I've always worn a diaper during sleep studies (had at least 8). I've been dry several times and made it to the restroom in the morning. I think twice I was dry when they woke me up, but wet as I stood up to make my way the restroom. The rest of the times I woke up wet.
If you need bedtime protection, then wear it. If you need to void during the night and getting up to use the restroom will seriously interfere with your sleep, then do what you need to do to get the best sleep possible. If they wake you in the morning, you should probably try and make it to the restroom if possible.
The real issue is, you're having a sleep study because of some sort of health issue. You don't mention what that is... doesn't matter. The technician may wake you up during the night to fit you with a CPAP mask because of apnea, or for another reason. The point is, they are trying to determine why you are having a sleep issue and what can be done to help. Feel free to void during the times they are interfering with your sleep, if it will help you sleep better afterwards.
