Negative pressure is how we are built to breath. I am looking at his as a DIY project for personal emergency use. Why do you not feel that this is viable for COVID-19? A proper protective mask on the patient would reduce their spreading the virus. Additionally if you add a valve and use the pressure side of your pump you end up with a Biphasic Cuirass Ventilator. There is research showing excellent performance as compared to pressure ventilators as well as some key benefits like clearing phlegm easily. When I looked back at the iron lungs and the history I found the Popular Mechanix article and prints for the wooden lung. This BCV seems like an excellent field expedient hack. It could be rock stupid with a manual bellows to start and everything else is a plus..Anonymoushttps://www.blogger.com/profile/12107411525122848158noreply@blogger.comtag:blogger.com,1999:blog-2217393939875576576.post-1169646480461622452020-03-17T19:34:21.062-04:002020-03-17T19:34:21.062-04:00Thanks, Yes That will work.

Not useful for people with COVID symptoms but can be used for other people in the hospital that will be triaged and competing for remaining ventilators. This is what you mean. https://www.youtube.com/watch?v=pvrUQCMa3a8 It is the same principle, Called a Cuirass ventilator. Uses much less space. Issues with CO2 retention in these patients though.<br /><br />Cuirass Ventilator the DIY way<br />I made a proof of concept of a negative pressure Curiass ventilator. The principle is to lower the pressure over the chest to make you breath in, then you breath out naturally, with a bit of help from the wetsuit squeezing you. I used a 12 litre box and a 12v airbed fan - using the deflate port to create negative pressure. The fan is powered by ...<br />www.youtube.com<br /><br />I am talking to this guyDreamerhttps://www.blogger.com/profile/13701195188549081875noreply@blogger.comtag:blogger.com,1999:blog-2217393939875576576.post-39607277507716993332020-03-17T16:58:56.686-04:002020-03-17T16:58:56.686-04:00positive pressure ventilators have to be more prec...positive pressure ventilators have to be more precise then negative pressure ventilators. how quickly can we build an old wooden iron lung?Anonymoushttps://www.blogger.com/profile/09545230206736385625noreply@blogger.comtag:blogger.com,1999:blog-2217393939875576576.post-54155051689985913062020-03-15T09:23:43.059-04:002020-03-15T09:23:43.059-04:00I am working on this project right now at this sit...I am working on this project right now at this site, with the help of many engineers.<br />https://app.jogl.io/project/121<br />You can join there.

I can help with some of the design/manufacture of some of the components.. we just need something to start withPaulhttps://www.blogger.com/profile/15693214643436271717noreply@blogger.com
