- G'day, everyone,
Nick here, from CPAP Reviews.
Welcome to part two of my series on the new Luna G3,
where today I'm gonna be showing you
how to change the clinical settings,
which are those settings like changing your pressure
and things like that, which are really important,
changing the mode of the machine from CPAP to automatic.
So I'll be going through that in detail,
so let's jump straight to it.
Okay, cheers.
Okay, so in order to get in the clinical settings,
each machine has a little trick,
and this trick is to rotate the data settings,
and then you're holding the click dial
and the home button simultaneously,
keep holding them in for about five seconds,
and then boom, we're in.
So on the top here, you can see three tabs,
Therapy, Comfort and Maintenance,
and we can rotate between the three of them.
To access a sub menu, we just click it in
and now we can go between
the different clinical settings,
and I'll run through them with you now.
So the top one's Mode, so the operating mode of the machine.
If we click in there, click dial,
you can see, we can change it between AutoCPAP
and CPAP
or fixed mode, most people will have it in automatic mode,
which means the machine will monitor your breathing
through the night and adjust the pressure accordingly
between the minimum auto, or the Min APAP,
and the max auto, Max APAP.
So the machine's determining the pressure
every minute of every night.
If we switch to fixed mode
it means we're setting the pressure,
the machine is just gonna do what we tell it to do,
it's fixed.
So if we click fixed,
we can set then our treatment pressure, which is whatever,
it'll just stay at that level all night.
So seven, it's currently set to.
Some people prefer that, but majority of these,
my patients and clients these days are on automatic mode.
So we'll leave it in auto.
Initial P is the initial pressure or the starting pressure.
So as it stands, it's at four.
This means the machine will start at four
and over whatever the ramp period is,
whatever the ramp time is, say the ramp time's 30 minutes,
it will gradually increase from four to seven
over that ramp time, over 30 minutes.
Once that 30 minutes is up,
the machine will then monitor your breathing
and adjust the pressure between the Min and the Max.
So currently set seven and 13.
We can change these values,
so that's quite a narrow range, seven and 13.
I'm just moving that down to five,
and then I might increase this a little bit to 15.
So I've just increased the range there.
If your finding that the pressure's getting too high
over nighttime and it keeps waking you up
and it's causing your mask to leak
and you're having a horrible time,
we can decrease this max auto,
so this is what we call capping the pressure,
which means the machine won't be able to go above
whatever level we set that at.
The downside of this is that if we cap it too low,
the machine won't be able to effectively
control our sleep apnea because it can't,
it might wanna go high than that, but it can't.
So we just need to keep a little eye
on our sleep apnea data,
in particular our AHI, apnea hypopnea index,
which is how many times per hour
we're having sleep apnea, apnea events.
If it's getting too high, if it's getting above 10,
you probably kept this level too low,
you might have to increase it a bit.
Okay, but I'll keep going.
SmartA, or smart auto, looks at the data
from the last five nights,
and it uses that as a reference
as to where to start the therapy.
I would always recommend starting with that off,
however if you are struggling
to get your apnea hypopnea index down,
you might wanna switch that on.
Sensitivity, that's the sensitivity of the auto algorithms,
so how the machine actually determines
how sensitive it is to your sleep apnea events.
If you go too high, if you go up to five,
I think it changes the pressure too frequently,
and it's not very smooth,
so you're probably gonna notice it a lot more.
I think the best to keep it between three and four,
if you go too low,
you're probably not gonna get fast enough action
with a CPAP therap to treat your apnea.
And Leak Alert means that if you turn that on,
it will beep at you,
if you've got too much leak with your mask,
so if you're getting, if it's not tight enough
or you've taken it off during the night,
the machine will start beeping at you.
I'd leave that off, to be honest.
If we click home now,
it'll take us back so we can move between these three tabs,
and I'll rotate across to Comfort.
Here, we can sit the Max Ramp Time,
I think it's 45 is the max it can go up to.
Wait, it goes more,
so you can have a 60 minute ramp with this one.
Reslex is the pressure relief function,
so we can turn this,
it should be on Patient, hopefully, when you get it,
but if it's not switched to Patient,
which means that you can determine it
just from the normal settings,
you don't have to go in the clinical settings
every time you wanna change that.
But it's pressure relief, so when you're breathing out,
the machine will reduce the pressure between a value.
So the more you go up, if we go to three,
we're getting more pressure relief.
The machine's gonna drop that pressure
as we're breathing out,
to make it easier for us to breathe against that pressure.
Just have a play with this,
you know, see, most people would probably have it on three,
they probably like it dropping the pressure.
But if you're an experienced user,
you probably don't need it,
and you might even find that that drop in the pressure,
throws your breathing a little bit.
So just have a play with the different numbers here,
one, two and three, and see which one
you find most comfortable.
I'm gonna leave this on Patient for now.
Auto On and Auto Off, pretty self explanatory.
Auto On means you can put your mask on, start breathing,
and you don't even have to touch the buttons,
the machine will just kick on and start delivering pressure.
Same with Auto Off, take your mask off,
the machine will stop.
And that's the bottom of that one.
And then home, and then we've got Maintenance,
which is, you know, shows how many hours
you've been using it for.
You can run a Mask Test if you want,
which will run the machine between different pressures
to make sure that your mask is sealing well.
And you can Restore Defaults
if you wanna just restore the machine
back to a factory setting,
Erase Data, and do some other bits and pieces.
But you don't have to stuff around too much in that.
So we'll just press home
and then home again to go back to the main screen,
and we're good to go.
And then it'll show us just the basics here.
So we've got our Min, our Max,
and the Reslex's currently off.
So if I wanna change that Reslex,
I just go to settings,
and then I can just rotate this down to Reslex here,
click it in, and now I can change that.
Zero, one, two and three, I'll put it at three.
And away we go, back to home.
Cool.
So this machine here,
I'll just check what the Ramp Time is there.
you've got ramp,
Ramp Time's currently 10 minutes.
So let's put that up to say 30 minutes.
So as it stands, this machine had an initial pressure
of four from the clinical setting,
so over 30 minutes, it will go from four to five,
which is the Min value.
And then once that 30 minutes is up,
it will then adjust the therapy between five and 12
for the rest of the night,
with quite a good amount of pressure relief
as we're breathing.
I hope that's helpful to you.
What we can do, and we'll just go into this
'cause it's pretty cool.
What we can do is if we go to Report here,
and we go to Usage Summary, click that in,
we can rotate the dial to seven days,
so just rotate the click dial to seven days,
'cause you wanna use an average, the last seven days.
You can use
this value here, the P95
as a guide for your max auto limit
of where to cap the pressure,
okay?
'Cause P95 means,
in order to control 95% of your sleep apnea,
you need that value or less.
So an example of 10, P95 of 10,
in order to control 95% of your sleep apnea,
you need a pressure of 10 or less.
So if we set our max at 10,
we know we're controlling 95% of our sleep apnea.
Hope that helps.
But yeah, that's it.
It's good to be able to change these values
because, especially if you're finding
the pressure's too high, that's the main thing.
If you're finding the pressure's too high,
it's causing you to wake up
and get really disturbed sleep, you need to cap that max,
all right?
Also, if you're finding it hard to breathe in the beginning,
you're feeling suffocating,
you might wanna increase that value
because it means you're gonna be getting more air
through the mask.
So you can play around with these settings,
it's not gonna hurt ya,
find what's comfortable,
but then just use your Report
to check your apnea hypopnea index,
or as you used, seven days, so an average of seven days
or more, never just use one day.
You can check your apnea hypopnea index,
you want that ideally less than five,
but less than 10 is still fine.
And then you can also check your P95 as well.
Cool.
