Can't find any detailed AHI, AI & HI data from Bipap S/T

dsm · Post by **dsm** » Sat Apr 29, 2006 4:19 pm

2nd day of using Bipap S/T & now am having some odd issues re trying to read the data off the machine.

I am assuming that the Bipap S/T does provide detailed data on AHI,SI & HI.

When I down load the nights data the results are not what I expect ...

1) When I request a detailed interactive report 'Type of Report = Full Details'
I get 7 pages of data telling me every thing but the AHI, AI & HI.

Page 1 shows general compliance data
Page 2 shows a small graph called 'Patters of Use'
Page 3 is called Ventilator Long Term Trend & shows simple line graphs ...
- Average Pressure
- Breaths per Minute
- Tidal Volume
- Patient Triggered Breaths
- Peak Flow
- Leak
- Apnea Count (this line is averaging 61 ?)
Page 4 Ventilator Daily Details ( same as above but min by min)
- The Apnea count part of the above graph isn't present in this page
Page 5 is a continuation of the graphs from page 4
Page 6 Ventilator Statistics by Day
- This is just a summary of the averages from page 4

No detailed min by min/ hour by hour AHI/AI/HI

****************

So next I tried running My Encore to see what Derek's software might show.
But when I try to select the patient - I have created 3 patients named after the machines being used ...
1) Remstar AUTO
2) Remstar Bipap Pro 2
3) Remstar Bipap S/T

Derek's software shows old data from 1 & 2 but when I select 3 I get an Error ...

"Failed to load resources from resource file" This error implies that the data from a Bipap S/T isn't compatible ?.

The initial conclusion I have come to is that there isn't any of the detailed data that shows with the AUTO I am not sure about the Bipap pro 2 (due to a separate problem re its date), but as for the Bipap S/T it seems it provides the bare minimum of apnea info - just the average apnea index & no detail ?

I am wondering if anyone else has a Bipap either S/T or Pro 2 or BipapAUTO,

What data are you able to get from your machines in relation to AHI AI HI through a particular night.

DSM

##PS Encore Pro is at version 1.5.82 (1.5)
##My Encore is at 1.5B7

Here's a detailed report from the BiPAP-auto. It includes all the usual stuff, AHI, AI, HI, SI, FLI & NR seen with the Remstar-auto. It also works just fine with MyEncore.

I concluded after a little digging some time back that the Synchrony S/T did not record any of the apnea parameters you mention, DSM. Just thinking about it I wondered why that would be since the Synchrony was such an expensive machine, and concluded that the mechanism to detect apneas didn't need to be included for the S/T functions. Even detecting apneas on these machines would seem to require a different algorithm altogether.

Your S/T machine seems to be in a different class than the BiPAP-auto. At least it appears that way to me.

Bill

Bill,

I think you are right.

Ahh well, back to the PB330. Main reson I bought the Bipap S/T was to get both the S/T function and detailed nightly data on events.

Thanks

Doug

Pssst! anyone want a cheap Bipap S/T

DSM, yup, you have discovered the sad fact about the Pipap S/T. My DMe went to Respironics Rep and was told the machine is classified as a ventilator and doesnt have the reports we desired! I just had a 3rd sleep study at University of Minnesota and informed I dont have Central apnea as the first 2 studies showed, so no longer need a backup rate! I'm getting a series M auto as soon as available !I was glad to learn from your post the MyEncore failed for you as well as me on S/T. I kept getting same error message! Wonder if Derrek will update to encore Pro 1.6 ??? Dan

Thanks DSM for all of this testing. I have the Synchrony Bipap and have to run it in the S/T mode. I was really hoping to get information about my central apneas. Aside from being curious by nature , since my AHI is so high (128), I wanted to know what was going on when I slept. I can see from your results that I will get some information, but sadly not too much. There is another user here, Laurabel who ran into the same problem viewtopic.php?t=8126&

I still haven't even opened the software. Do you think the information available from the Synchrony makes it worthwhile installing?

To be honest, no.

I have switched back to my PB330.

The data from the Bipap S/T isn't what I was looking for. I assume it may be useful to a sleep clinic who may be more interested in the patterns of someone's breathing, especially if they have severe centrals, but I really want the AHI, AI & HI etc: data.

Seems that for some machines, being more expensive doesn't mean more sophisticated in data provision.

I will double check if the VPAP III S/T machines provide this data if so then I guess I will be looking at one.

Cheers

DSM

The S/T is a different class of device and the information provided is different.

Possibly but the Bipap S/T is designed for Sleep Apnea and thus someone's AHI and nightly pattern of AI HI is just as important as any other xPAP.

BiLevels with S/T have extra features to provided relief for people with experiencing 'centrals' - it seems perfectly reasonable to assume that the machine has as big a role with mixed apnea as with centrals only.

It really makes no difference to the desire to know AHI, HI and AI data.

I use the S/T because I have severe central sleep apnea. Essentially, I want to know everything that is happening when I'm sleeping, especially how often I am having centrals. Why wouldn't the S/T be able to provide this information? Since it can function as a CPAP as well, wouldn't the ability be built into it so that those users can get detailed information? And if it is there for the CPAP mode, why wouldn't the function be available for S/T?

Not a techie, just a disappointed user.

Sounds like another contributor for the Respironics users group, DSM.

You bet. I don't know how much I'd be able to help as I have no where near the knowledge and experience you guys have, but I can certainly support you on this. My sleep doctor was pretty pleased that I showed such interest in tracking the data. No reluctance there.

Bella,
If I understand correctly, the problem of central apnea is that you don't initiate breathing in a timely manner.

I once looked at the disppointing reports of a pb425 timed bipap - it reported breathing patterns.

Now, doesn't the Synchrony give you info about spontaneous vs. machine-initiated breathing? Wouldn't that be informative for you?

I might be all wrong - and will be very greatful if you could explain it.

Thanks,
O.

Ozij, as I mentioned earlier, I haven't installed the software yet. I do recall though a while back you mentioning that it should give me the information that I need. I think you even pulled up the information from the Synchrony machine posting at cpap.com. Looking back at what DSM has posted about the information that he got, I think that you are right. One of the items listed is the "patient triggered breaths", and another item is the "apnea count". If I have the patient triggered breaths and breaths per minute etc., I should be able to work out what I want, as you say spontaneous vs. machine breathing.

I think that the only way I'll find out is to get off my duff and install the software and hook up the machine.

Ozij & Bella,

The Bipap S/T data doesn't give the min by min (nor even hour by hour) Apnea events.

It merely has a graph with a straight line giving an 'average' apnea count - the line in this graph is dead straight so ids the average for the entire night.

The next page does give detailed min by min info on breaths etc: but the apnea data is left off this page.

I believe what Bella and I were expecting and hoping for was that there would be data in the card indicating at least when apneas were being detected.

The other problem with the av apnea data is that the figures it had for me showed an av of 72 which exceeds my 2 sleep studies which averaged 40.

The problem here is that the figure shown is meaningless as there isn't enough additional data to extrapolate any more detailed info.

I admit that I made the assumption that this machine would provide data similar to other types of xPAP machine. I know S/T models have the added feature of breath control.

The fact is I can't get any better data from my PB330. As for VPAP III - I have no idea if they offer any better data.

What I have learned re accessing detailed data is never to make an assumption about what a particular machine may report.

This has been a learning experience.

Cheers

DSM

AFTER READING YOUR POST I SPOKE TO MY PHYSICIAN, AND HE TOLD ME THAT THE CARD WILL ONLY PRODUCE COMPLIANCE DATA. NO EVENT LOG

Can't find any detailed AHI, AI & HI data from Bipap S/T
