This one uses manometers and graduated receptacles to control tidal volume, PEEP, peak and plateau pressures. It uses a flow control and 555 timer chips for mandatory breathing and I:E ratio.

    I remember this video 10 months ago. I watched it and decided that I needed to change fields as I figured medical device repair would be in high demand. I left the oil and gas industry and now repair ventilator and anesthesia machines for hospitals. Thanks AVE.

    You can't fake this sorta gestural, irreverent grace. We laugh, and we end up smarter for it. This is why I watch this channel. Oh wait, that's right – there's about 555 reasons I watch this channel. Loosely related… in Thai, the number "five" is said as a high-toned "ha!". It's a texting slang for laughing, therefore "555" = "hahaha!" So when I read this title, I impulsively tried to puzzle out what's so funny about the timer. Maybe it's the meter that gives the measure of the man, maybe it's the mandatory breathing. Still, "555" and here's to fluid dynamics, breathing and tactical pants.

    Do not go on a ventilator, the minute you do, you're 50/50 of coming off it

    I started off working with the Bird ventilators! Worked with just about everything else since then. Did critical care and trauma and rescue. Cardiopulmonary Practitioner at your service!
