Cheyne Stokes Respiration ...

Well I forgot to put my SD Card back in.. but I had AHI of 4.8 is that ok? I’ll look again tomorrow.

Not really its classed as treated (treated is any AHI less than 5) we aim for less than 2

Yes.. an ahi of 4.8 is like someone poking you in the ribs ever 13 or so minutes... Hard to get good rest like that.

Well it looks like I had quite a rotten night last night the second night at 9 with a ramp of 6-9 in 10 minutes. The last hour or so I was probably awake. No CSR event which was I suppose the only plus. I noticed that I had hardly any obstructive events only CA ... how do I get rid of these?

Were you actually asleep when those centrals/CAs were flagged?

You might want to take a crash course in figuring out asleep flagged events from awake/arousal related flagged events.

It is possible that the hyponeas created a sleep disturbance/arousal and the centrals are a by product of the hyponeas.
They do sort of all cluster around each other. More pressure is needed for hyponeas......if you were asleep for sure when they were flagged. You can have false positive flags of hyponeas, centrals and OAs. It's not limited to centrals.

If the centrals are real and you are asleep for sure when flagged then more pressure isn't the fix for centrals though.
You can't fix them with this machine.

So the first thing to determine is sleep status....were you really asleep when all this stuff was flagged?

Hi,all a real newbie here,diagnosed properly last month, but my wife has known for years!

Got my Resmed Airsense 10,with a climateline air hose,I started with a full mask but switched successfully to the Reasmed n30i and chin strap.
Having starting out with an AHI of 59, my first proper night was a satisfying drop to 3.90 ,as the week rolled by and I got more use to my future sleeping accessories .I spent time on this forum getting my head around all the acronyms,software etc,I'm on a steep learning curve.


Having had 3 Myocardial infractions (while asleep)since 2004 and 7 stents over 3 visits to hospital on 3 continents.I was disappointed to see 5.79% Cheyne Stokes Respiration show up on last nights stats and a AHI 6.70.
Obviously I'll monitor myself over the next few days,but do CSR's happen regularly or randomly and are there instances that can cause false positives.



Thanks for the support
Oscar shows Climate control is manual but the machine is set to Auto

Ignore. Known bug in the settings data area.

Were you by chance awake or semi awake when all that CSR stuff got flagged?

Thanks for the speedy reply.

I think I was semi awake,as the nasal cushion had move and was leaking a bit.

I think that there is a good chance that the CSR stuff is related to being awake or semi awake. The breathing prior to all those flags looks a bit like arousal or post arousal breathing to me and if you can confirm a good chance you were awake....then we ignore any awake or semi awake flagged stuff. You have to be asleep for anything flagged to matter.

Just watch more nights...most of the time when people have real CSR stuff they have it every night and more frequently during the night than your just once or so.

Set it on the back burner for now and try not to worry about it unless you start seeing a lot more of it and especially if you know for sure you were asleep.

Awake/semi awake breathing is very irregular when compared to asleep breathing. These machines can only measure air flow and they don't have a clue if you are awake or asleep. They can and will flag awake breathing irregularities by mistake.
So just keep one eye on things but at this point...try not to worry about it.

If you want to learn how to zoom in and figure out awake vs asleep breathing the videos here will help.

I also get CSR's but quite regularly. If I increase my cpap pressure the CA's increase quite dramatically. I have found that by keeping the pressure lower (cpap 6 ) and increaseing the EPR to max (3) I can keep the CA's to a resonable level. Yes the min pressure that can be achieved is 4, but if I increase the EPR to 2 my CA's increase ( placebo??? ).

I have contacted my sleep clinic and they are not worried about it, last week saw my cardiologist and he said that many things can cause the CSR's and if they are not consistent throughout the night but in fits and spurts not to worry.

So yes it is disconcerting to see them on Oscar but as long as they don't happen all night long I am going to put my head in the sand and ignore them for now.
