Has anyone used this steam-breathing device -- wello2

[runcyclexcski]

Just came a cross a recent research paper on this Finnish steam-breathing device. It looks like a glorified teapot, but it also comes with a nasal mask which is kinda cute. The paper also has a conflict of interest, becasue the lead authors is the CTO with Wello2. Oh well, at least they declared it. They also wrote that they excluded people whose asthma gets bad in the sauna (this is Finland) -- I wonder how common this is.

Here is the paper. The PDF opens free on my device (i.e. the authors must have paid $2-3K for free access, gotta have good publicity for their teapots! ).

Looks as though it's modelled on the old china netti pot I've known singers to use

Reminds me of the nelson's inhaler my grandmother had!

I bet it's a highly innovative PATENTED design though :). The way IP protection works is beyond me.

This was brought up not long since,maybe a month or 2 ago if u want to do a search x

Patk1, thank you for letting me know. I tried to search for this keyword -- wellO2, -- did not find anything. Maybe a more generic term was used in one of the previous posts.

I went ahead and rigged an analogous device myself, and hooked it up to my breathing machine. Took me about 1 hr . Humidification does work quite well, although the act of boiling water in the chamber generates a lot of microscopic aerosol water droplets (about 1-micron in size) which could potentially be a trigger for some folks. These were not "fog" per se -- these were rather aerosol droplets released by bursting of bubbles on the surface (or so I beleive).The authors of the well O2 research paper excluded those for whom saunas were a trigger, and I know many people on this forum get unwell while taking a shower. So.... I think humidification should be done in a more controlled manner, w/o brining the water to the boiling point. That, I believe, requires a bigger/more sophisticated device, not a glorified cooking pot.

At least you've tried.you shld be a development engineer!

[runcyclexcski in reply to Patk1]

You are too kind, Patk1. I am unemployable as such, there are proper engineers. But they are working on other problems, I guess.

Here is an old paper on ultrasonic-generated distilled water droplets inducing a bronchoconstriction in asthmatics. About 50% of tested asthmatics had this reaction, whereas all of them reacted to metacholine. So, it is a thing, and it's consistent with some folks on this forum and myself getting worse while showering. I get no bronchoconstriction when I breathe humid (80%), but aerosol-free, air.

I'll read up on ths later,thanku x
