Still CPAPPing OK.

I’m persisting with a new CPAP mask I  bought from a hospital after a sleep lab night, where they said I needed 15 cmH2O pressure to control my sleep apnoea. Its a Fisher & Paykel nose and mouth mask, and feels quite different after 13 years of my old nose mask.

I’ve increased the pressure gradually from 9 cmH2O to 10 cmH2O, and it seems quite strong.

But I’m persisting, trying to find how best to seat the mask on my face. AND I’m drugging myself with 2 Temazepam nightly, or one Temazepam plus a Valium (Diazepam) as well.

The sedatives help to keep me asleep until I get used to it.

I cannot see any way that I could use 15 cmH2O pressure. It just blows out of the mask onto my face! Most unsatisfactory state of affairs.

Perhaps the pressure indicator on my old Remstar Plus is not  calibrated correctly. That means I traipse over to Brighton  to have it checked out. Worth while to do before I launch off into Tassie, I guess. I’ll phone them up.

Goodnight, sparse readers, if any at all!

Me and a rubber mask.

Last Monday night I did a Sleep Lab. That’s where you sleep overnight in a hospital suite, where you are wired up by dozens of wires  – especially from the skull – for the different patterns of brain waves during sleep- and also over the body, to pick up other muscle movement.  And you get monitored by a nurse in an observation room. They can see you by infrared light camera, plus via all of those wires. They go through the wall to a computer, and you are watched by nurse. They do this to a group of people, each in separate rooms.

That goes on all night. In a later appointment, the sleep specialist discusses the ways you went into various levels (4 levels) of sleep, plus REM sleep. As well, snoring is monitored, and the breathing pattern. They’re looking for the occasions where the soft palate collapses, blocking the airway and causing cessation of breathing – that’s sleep apnoea. As well, they monitor the level of oxygen in the blood.

All of this is in order to check my performance using the CPAP  (Continuous Positive Airways Pressure) device  that I’ve been using most of the time since 2004. Yes – that’s a long time!  I’ve been using a CPAP pump which delivers slightly pressurized air through my nose to my lungs when I sleep. It was set at 9 cmH2O, meaning the pressure of a column of water 9cm high. The current doctor, whom I met when a different illness put me into hospital, picked me up as a “likely customer”  when I was using the CPAP device in hospital. He does sleep labs. I hadn’t been checked for just 13 years!   So I did a sleep lab!

It was OK – I sleep well with my own mask, which covers only my nose, into which the pressurized air is delivered at 9 cmH2O.

BUT … they found that to prevent the collapse of my soft palate, they needed to increase the pressure from 9 cmH2O up to 15 cmH2O.

BUT again … they found that at that pressure, the air escapes from my mouth! That wasn’t happening previously, but is undesirable because it reduces the pressure applied to the soft palate .

HENCE .. they needed to use a different mask which cover my nose AND my mouth. That cost me the tidy sum of $280. The Sleep Lab itself cost me zilch – I suppose because I have a high level of private hospital cover. SO … they gave me a free sleep lab, with free supper and breakfast, and  close attendance of a nurse during the night.

Here’s the problem! They adjusted up the pump pressure of my own pump to 15 cm. —————–

BUT … when I tried on my expensive mask the first night at home, it was hopeless! The pressure was tending to blast it off my face, making farting sounds. I just couldn’t use it!! What to do???

I found that I didn’t have any instructions in my booklets with the REMSTAR Plus pump from 2004 which enabled me to reset the pressure back to 9 cmH2O, so that at least I could operate at a pressure I was used to. There had to be some trick that enabled the nurse to change the pressure of my own pump back and forth.

Google! That’s the trick. I soon found that I could get into the control settings ONLY IF I held the unplugged it, and held down all 3 of the buttons it has, then plugged it in again! BINGO!

So far, I’ve had a night where I’ve set it from 9 cm to 11 cm, but even that modest increase tends to cause my new mask to leak at the edges, with those “farting” noises! I could only sleep if I tied the mask down quite strongly against my face. So that was last night. not a lot of fun. I got to sleep about 1 am, woke up for the toilet at 2:30 am, then woke up again at 5 am, to a freezing house. I toileted again, and gave away the mask and pump for the night.

Not sure what I’ll do tonight. Might fiddle with the adjustments and loosen them up a bit to see if I can work out some position on my face that sits right without pressure escaping with those peculiar noises. You can’t sleep like that, and neither can my wife! These masks are sold all over the world – surely there’s some way of using them properly!

Perhaps I’ll Google onto a user’s group … good idea!

More to come.

 

Well, that was a bloody useless attempt at a new start, wasn’t it?

Almost 3 weeks have passed since I started a new train of blogs. And now I’ve just run out of energy and ideas. But I’ve been overwhelmed with all sorts of things to do around the house, and am plugging away at HTM/CSS code  towards the display of all sorts of good stuff from our trip from Melbourne to Cairns and back in 10 weeks.

But I’m getting there, and am sure it will be worth it. I’m looking forward to a month’s caravanning in Tasmania starting October 19th. Any tips about what to see? That would be much appreciated.
