Haven't read this.
The Actore: Cool
b1-67er (P.E. in CA): That's a good idea because all the parts touching the patients air already meet FDA requirements.
TA: Interesting that they lifted liability for machines dealing with this virus. I think that's a really good idea for now
67: Absolutely. No company in their right mind should touch it otherwise.
TA: Did you see that there's a video game controller in the picture?
67: Good idea on the controller. They are pretty bulletproof. Trouble is there will instantly be a controller shortage.
TA: Yeah, But they are literally in just about every home. And I think people will happily volunteer one if they know it will help a relative in need
Although their kids will fight them on it because they won't know what the heck to do with their time😂
67: That's not $100 worth of stuff. Maybe $800 or so plus labor.
TA: I was thinking the same thing about the cost. Controllers alone I think are worth $60-$100. However 800 still sounds a hell of a lot better than $30,000
67: True. It's plugged into a white sheet metal box sort of hidden under the laptop. I wonder what that is.
Plus I'm sure it lacks a lot of bells and whistles and reliability testing.
Still useful.
Great in a "I'll take any ventilator I can get" world.
TA: Yeah, you would know very well that dynamic. I'm also wondering about the sensors and feedback system because each patient has different volumes of air and requirements that they will need which will have to vary throughout their treatment.
Another thing I have to worry about is can those ambo bags last for up to four weeks? I think they were meant to only last for a short time until they can hook a person up to a ventilator according to the article. There's a huge difference between an hour's worth of use <and?> four weeks which could literally be 4 million cycles if their million cycle per week number is accurate
67: Likely you would wear them out. But even if you get a week, you could swap them out. Sensors may well be the bottleneck to quick production. The controller on the left end of the plywood is probably doing that decision making.
The red/green/yellow object on the end of the bag is some kind of visual pressure sensor. It looks like a bypass sensor from a hydraulic filter.
You may adjust the pressure manually.
TA: Agreed.
Very cool. Although if it <has> to be adjusted manually... does that require a person to be there 24 seven?
