New home sleep study diagnostic equipment

Postby picklish » Tue Jan 10, 2017 11:09 am

Anyone have any experience with BresoDx? I've just got a leaflet about it, and the prof wants us to test it on a willing patient.

https://bresotec.com/what-is-bresodx/

Apparently using acoustics of breathing to record apnoeas - I'm unsure about how it would determine centrals, but maybe one of you guys have some idea of it?

Does it feel like the automation of scoring sleep is getting closer? Certainly no software I've used (respironics/resmed/xltek/visi etc) have ever had particularly accurate automated scoring for home respiratory studies, never mind PSG, but perhaps that's about to change?

Sounds like Rockwell's latest.

j/k

Almost getting to audio sleep scoring, though there used to be audio scoring via hi-speed playback of Oxford Medilog recorders back in the day. SWS sounded like a train, and REM were birds(?). Not sure, as I never did it, just heard about it.

I had also heard about the audio scoring of ye olde past, and have wanted to make a concept album about sleep disorders by converting the .edf files into .wav files. Sadly, i've never understood how to.

So, off the bat, sounds like total rubbish to you?

No, was just amazed at the size of the thing. It records "snoring". Same can be done with Android app for free.

Was just joshing.

Would like to hear back from you on how this EDF to Wav project worked out, and tweaks/settings to get functional sounds from the software. Would be cool.

A company who I do some work with has started using this device and direct me to https://bresotec.com/research-publications/ when i query it's reliability

I looked at an example and made the comments on the attached image. I'm concerned by the lack of ability to see the raw actigraphy data, which they are using to score sleep/wake. The sleep latency/night time awakenings was not similar to the patient self report. Any other issues with this thing that you can think of?

Regards
Stevie

How did your EDF to Wav project turn out?
I agree with your feelings about the above tracing.

He said he never understood how to convert them.

Thanks Ray, but the last post prior to picklish's last post is this:

I had provided links to EDF to Wav tranforming software and was inquiring as to how the project turned out.

Did you read the thread?

I did figure it out, but have left it for ages then forgot about it. I'll get back on it and let you know
