Latest User's Manual to SleepyHead

Post by VPAP » Mon Mar 02, 2015 4:50 am

Hello. I have a question about SleepyHead. I use the latest version. This version I found out has the Unclassified Label. The other user's manual does not discuss stuff like the Unclassified Apnea. Is there a user's manual of the very latest version where they discuss the Unclassified Apnea? I want the latest User's manual. Thank you very much.

Manual? For SleepyHead? The closest thing I know of is a search on this forum, or brain picking on some of the really smart forum members.

I assume you mean unknown apnea. I wasn't aware of SleepyHead calling something unclassified.
SleepyHead is just reporting what the machine is reporting and you would get the same "unknown" category flag if using ResScan.
Did I send you the ResScan Guide? If not, here it is
http://www.apneaboard.com/ResScan_Inter ... -Guide.pdf
What SleepyHead shows is what ResScan would show with one minor exception if you were using the S9 Adapt which you aren't.

Unknown apnea is simply the machine not knowing what type of event it senses...it can't decide if it is obstructive or central in nature. Most of the time when we see "unknown" flagging it is associated with large leaks. Leaks not bad enough so that the machine can't sense anything but bad enough that it doesn't know what it is sensing.

On occasion the machine may simply not have a good idea about what it is sensing and the leak isn't bad. We don't know why.
Unless you are seeing a lot of them we don't worry about them.
But the names that things are called in SleepyHead are the same as what you would see them called in ResScan because it is the machine doing the naming.

The exception would be if someone messed with the customization feature for changing user flagging parameters so you can get some flags with SleepyHead that wouldn't be found on the brand name software. I don't recommend that users use this feature in SleepyHead until they are very experienced in what their software is showing and have a really good understanding of what they are looking for.

There is a glossary of terms that are commonly found in SleepyHead. It is nothing more than definitions taken from ResScan or Encore because the terms that are found in SleepyHead are the same terms that are found if you were to use name brand software and in your case since you use a ResMed machine...ResScan.

Thank you so much. Yeah, on SleepyHead, it doesn't label as Unknown. On Sleepyhead that I am using, it labels it as Unclassified. I looked around, and it appears that this would happen if there were large leaks, but I had looked where my Unclassified apneas were, and there were not really any sort of leaks. Thank you very much for the guide. I think that I am going to download ResScan today and see what I can do with it.

SleepyHead used to call Unclassified apneas as Unknown apneas...or at least I think it did.
Perhaps with this latest version Mark decided to use "unclassified" vs "unknown" or maybe I am just dreaming up what I think it used to be.
I haven't seen an unknown apnea in so long I can't remember what it was called or with which version of Sleepyhead I am using.
I am using the latest version though..

So...it doesn't really matter what it is called...unclassified or unknown...they are the same thing and it's the machine that is doing the name calling...not Sleepyhead. SleepyHead just reports what the machine is reporting and doesn't really do any analyzing until we get into the customization stuff with user defined parameters and I don't advise doing that.

Ohhhhhhhhhhhhhhhhhh. OK. I see. I understand. So whatever is happening, its what the MACHINE is calling it. So, I understand now. the Machine is ultimately what decides to call these events. It is not with SleepyHead. Its the MACHINE that is labeling these events. WOW! All right. Thank you very very much.

Correct....SleepyHead is just the reporter of things...it's the cpap machine who does the name calling.
You can use ResScan and pretty much see the same things except some numbers varying slightly due to rounding up or down because SleepyHead goes to 2 decimal points and ResScan goes to 1 decimal point.

That is so amazing. I love my VPAP S9 auto. You know, the old PAP therapy machines used a card known as Encorepro and you had to have a card reader, so you could not just put it into your computer. I am sooooooooooooooooooooooooooooooooooooooooooooooooooooooo glad I do not have one of those anymore. That sucked. Now, I have the wonderful blessing of being able to see my data. I love being able to see the waveforms like Minute Ventilation, and also being able to see my tidal volumes. Its really nice. I am also glad that I can see the flow waveforms, and the Pressure waveforms. i was fooling around with my VPAP and put it into a straight CPAP mode, and was playing with the EPR function. One thing for sure. In a way, EPR defeats the purpose of CPAP. If EPR is turned on,and set to 3, then,if yourCPAP pressure is set at 10cmH2O and it is what is required to treat the Obstructive Events, well, if the EPR is set on 3, the pressure is decreased to 7cmH2O and that is in a way, NOT GOOD, for some patients! If you require CPAP of 10, and its going down to 7 when you exhale that can be a problem, and can make Apneas come back.

Did you know that?

I'm glad that I am using BiLEVEL support! Of course, they putme on CPAP in the Sleep Lab, but they could not get my Apneas to stop in the Sleep lab with CPAP, so they switched me over to the BiLevel mode.

Yes, I knew that about EPR. It can sometimes allow apnea events to happen during that drop upon exhale for some people. Not all people though and even for those that it does happen there is a way to remedy the situation if they find that they like/need EPR to be more comfortable. All that needs to be done is a slight pressure adjustment upwards so that the drop in exhale doesn't allow the airway to collapse. It's an easy fix and the comfort of EPR will usually offset any initial difficulties someone might experience with starting out with a slightly higher pressure.
The same thing is true with your VPAP S because even though you don't see EPR by name...your Pressure Support (the difference between inhale and exhale) is pretty much EPR by a different name. Your EPAP pressure is essentially what someone who is using EPR would see upon exhale and your IPAP pressure is what they would see on inhale. The main difference between using cpap with EPR and bilevel with pressure support is that EPR is limited to a 3 cm maximum drop and your Pressure Support doesn't have that limitation.

Your VPAP S set to bilevel mode is really nothing more than CPAP with EPR that can go higher than 3 cm. There might be some tiny timing differences but on a whole bilevel is nothing more than cpap with more flexibility in exhale relief.
Now that's how it is with the Non ASV bilevel machines....once we get to the upper end bilevel machines there are more differences but for the "plain" bilevel machines it is just cpap/apap with more available pressure support or reduction during exhale.

I have always thought that whatever it takes for someone to sleep comfortably is what a person should do. Some people look upon any exhale relief as some sort of crutch that is to be looked down upon but I don't feel that way. I think that anything that allows someone to be more comfortable will translate into sleeping better and good sleep is the name of the game with all this cpap/apap/bilevel therapy. Of course we have to deal with the apnea events but we also have to be comfortable with how we are dealing with them because if we can't sleep...the best therapy in the world is useless.

I totally must agree with you. Essentially BiLevel is a wider EPR. So if a patient is on CPAP, and they need PER, then, you could slightly increase the CPAP pressure above the Point where apneas and other Sleep Related breathing events are stopped, and then initiate EPR so that the exhalation is essentially set to allow the pressure to decrease dto the Apnea relief pressure. EPR is just a nnarrower BiLevel hince if you were looking at EPR on SleepyHead, you would actually be able to see the IPAP and EPAP level, because essentially, IPAP is the set CPAP and EPAP is the EPR RELIEF SETTING! Thank you for pointing that out. I think that whatever can be done to help patients sleep with PAP therapy, SHOULD BE DONE. Because otherwise, patients have a higher risk of being Noncompliant, and when a patient just puts the PAP therapy machine in the closet and never uses the PAP therapy machine, IT DOES NNOT HELP THEM.So EPR if it helps to increase compliance, its a VERY GOOD THING. PAP therapy sadly has a LARGE Noncompliance percentage, and that's SAD, because Sleep Apnea CAN KILL is not treated. It can lead to such serious health problems like Strokes, Diabetes, OBESITY, heart attack, also known as Myocardial Infarctions, etc. It MUST be treated.
