Using a Bipap Auto SV and using a Vpap Adapt SV

dsm · Post by **dsm** » Sat Jun 28, 2008 3:12 pm

Danmc,

If you can get ...

1) A machine that provides detailed nightly data (such as the Bipap SV)

2) An SpO2 / pulse machine (pulse oximeter)

3) A device that detects abdominal effort (breathing effort)

4) A device that wen place at the mouth/nose detects the minutest airflow

These are a rudimentary sleep lab. You could add a video camera to record visually what the pulseox and machine are seeing.

3 & 4 are not complicated devices & made from simple principles.

Cheers DSM

This is really off topic in this thread, except perhaps a tangential relation -- I think M seried Auto is over counting Hs too. I have great respect for the very active people in this discussion. Would you kindly take a look at my relatively new post below and provide your valuable opinion? Thank you!

DSM,

Thanks for the reply in the other thread.

I would be looking forward to your write up. I have not studied in details other machines and algorithms than CPAP Auto. I am into algorithms, I have been doing sw for >40 yrs, and have designed my own Visual Evoked Potenatial instrument and got FDA approval (detected with scalp electrodes, almost 2 orders of smaller magnitude signals than REM)

That sure sounds interesting, feeling_better!

Is your VEP device used for diagnostics, biometric identification, or...?

For diagnosing visual acuity objectively -- that is, without the patient having to answer any questions. I had done some research on this while I was teaching in a Univ in the early 70s. Later when my son developed a condition (at age 6 mo) that needed testing, I decided to develop a home-brew system, using a PC for the first time for such an instrument -- just before home computer became a PC, which grew into a company. I had two systems being tested in big name hospitals in this area. My company was eventually sold to a National med instrumentation company, which after some major reorganization resold an arm of the company which included that part, and the second company dropped my product area silently. Such is life

What an interesting and cool project!

1. I haven't decided on machines yet (hiring resmed apaps)- I really am new. I kind of got sidelined somehow by the local sleep lab (asked too many questions?) so titration was not completed. I took over myself. I assume that I will need some experience with and possibly ongoing access to machines that assist titration by virtue of being auto, though I am not sure yet. Anyhow, my general plan is buy a vpap auto then progress to the bipap sv if it still seems likely to offer better quality.
2.Ordered reslink and oximeter. Debating buying wristox plus software as well for various reasons.
3. Abdominal effort - no idea here yet. Doubt it will be difficult to source or mimic standard gear.
4. Nasal canula type thingy - debating the merits of the resmed device. Havent spent much time on this equipment either.

What is your opinion of the eeg/ecg being worthwhile DSM? The sleep lab here wired me up like an Xmas tree. I have to admit that I like the idea of neural feedback games as much as I want them for sleep studies.

Microphone as well? As simple as video so why not.

I have poked around trying to find out if I can hire or buy anything like the bipap sv locally. Local suppliers get funny looks on their face when I even mention bilevels. Seems unlikley that I will have much luck. Do you mind if I ask where you sourced your machine (s)?

I hope experienced users like yourself do not mind my interjecting when it is obvious that I have little experience - I really opened my mouth because I do find extra hardware and software well worth spending the cash on - it's likely that I will buy a lot of gear. So I'm keen to find people who have a similar outlook. Many people apparently see extra hardware beyond cpap unneccessary so it's difficult to subtract economic considerations from real info about the machines I am interested in.

Danmc

I was half joking about the home sleep lab - I must admit I am comfortable with just an SpO2/pulse recorder and the nightly data plus feedback from my wife and the data from 2 sleep studies done at the Royal North Shore Hospital sleep clinic.

Are you in Oz ? - if yes then the Respironics gear is for sale here - Mayo Heathcare are their Australian agents.

I have come to regard the Bipap SV as a remarkably versatile machine that can be used in many ways - but must be careful what I say, the 'Cpap Nazis' are now among us (forgive me Jerry Sienfeld)

Danmc, I have no clue about costs or specifics. But there are various "turnkey" home-diagnostic systems that include multiple data channels and scoring software.

Soup->soap->cpap .... pretty close it looks to me

Aha, so all those years I was getting that New York accent wrong.
I used to wonder how they got their therapy out of a paper cup

The machine has a "maximum pressure support" of 16. The default" number for the p.s. is 15." Is there any reason why they co. did not must make the two numbers the same, ie 16? They are so close. I increased the p.s. to 16 myself just because I figured it was there and would let the machine use it it if felt necessary. You people are certainly well versed in this machine. Any info you have apprecd.

I can't think of any reason why other than the latest version of the Vpap SV goes higher that the current one. Banned can confirm but I think that the MaxPS now goes to 20 but the default remains the same.
