The SleepCube was a private purchase, as way back then my local sleep clinic assessed patients by filming them overnight, whilst wearing an oximeter, and only issued CPAP machines without humidifiers. There was no remote monitoring and…"

Noisy machine in the middle of the night.
Just a quick question for my more experienced fellow hose heads :)
I am waking up in the middle of the night with the machine working very powerfully and noisily. It seems mostly silent when I first go to bed. I am assuming this is the machine working well during periods of apnoea - is this right? I end up usually taking the mask off at this point if it has been on for a minimum of 4 hours but want to get through the entire night with it ideally.

Hi Amanda, do you have a humidifier? If you have then it could be water in the pipe thats condensed. A hose lift stops that problem by letting it drain back into the machine. plus a hose cover.
If not I will leave it to Kaths better wisdom.

It could be what David said, but it also could be if you have an APAP machine (the automatic CPAP which increases pressure to treat your apnoeas? I'm guessing that with you being so new to the world of OSA you're being titrated on APAP to check the pressure you actually need. Are you due to go back to the sleep clinic soon?

Yes am going back next week....to pick up a humidifer as I am waking with a very dry mouth. Am also going to see if they will let me trial any other masks to see what feels best.

Amanda, it may also be that you are still getting used to the slight noise most machines make. Perhaps previously you snored or there was no noise at all so you need to get used to a new noise. When we go to bed we are normally tired and don't hear it as much, then in the middle of the night when it is quiet, we are more alert to it even though we are asleep but maybe going through the light stage of a sleep cycle. After a year I still wake up but now can usually go back to sleep. What I do is leave my mask on and turn the machine off for a couple of seconds and my ramp is set for 30 mins so it basically starts again like it would at the beginning of the night. Not sure if your machine has the ramps feature or whether you can adjust it.

That's good to hear. 4 hours treatment's better than no treatment, but hopefully when they sort out your settings you'll have good CPAP therapy for all your apnoeas. The humidifier will make a big difference, but you may need a Hose Cover to ensure you don't get any rainout. There's nothing worse than an unwelcome face shower in the night LOL. People say it also cuts down on the noise of the machine, and did you see that comment on Facebook Amanda, where one of the customers had bought one to stop the noise of his hose banging on the side of the caravan :-D ?

Hi Amanda, I will throw in my two penneth for what it is worth. Sometimes I wake at night and my machine seems to be making more noise than usual - the most annoying is the whistle which only happens occasionally but once you hear it, it is difficult to switch off from it.
I don't really have an answer to the why.... but tend to agree with Terry's theory about noises appearing louder in the night. If I have to reset my mask for any reason in the night I always start from the beginning, i.e. putting the ramp on to allow me time to get over before the full pressure kicks in - no point in making life more difficult than it has to be.
You should find the humidifier a big help - and the hose cover is a must - not only does it stop rain-out it reduces some of the 'air' noise - it also makes the experience more comfortable as you can't feel the hard hose against your skin.
I hope you get sorted soon, the benefits are worth the effort in getting it right :)

Diane, I'm wondering if you have the Sleep Cube, as the humidifier has an annoying habit of making a lot of noise if you haven't fully shut the drawer to it. I used to make sure I gave it a good push to make sure it was in place properly.

Solved it! I am waking when the pressure is at it's max. Have played around with the mask and also discovered the ramp feature. Last night I slept from midnight to 6.00 with the mask in place - no middle of the night wakings.
If I didn't have this cough and cold I would feel fab but as it is I am just experiencing viral exhaustion. Hopefully once it's gone I will get the full benefit of it.

I thought it would be that Amanda, as your minimum and maximum pressures will be set wide apart from each other whilst they're titrating you for the correct one. Mention this when you go back, but am sure they'll naturally be changing the pressures for you to suit. Often people are taken off the APAP's and sent home again with a CPAP (meaning the pressure doesn't change at all, except on the ramp setting). It depends what machines your clinic supplies people with.
