The amount of pressure ventilators are exerting on injured lungs leaves little room for error, doctors said." Since sedation is required for using a vetilator and the mortality is 85% anyway perhaps they should be used only when success is likely. CPAP BiPAP do not require sedation so if they fail the patient will not be so likely to die. After the 1995 Chicago heat wave the mortality of the aged was lower than normal the next year, so there was little net change. So not everyone may not need heroic efforts to survive. The grassroots efforts should be directed toward sewing face masks with nonwoven inserts, makeing face shield head bands with 3d printing, and converting shipping containers so that the Batttelle design can be implemented by every welding shop. Drycleaners and anyone with a vacuum desiccator and a supply of hydrogen peroxide or other appropriate gas should be able to decomtaminate disposable PPE money and other articles in short supply. https://theweek.com/speedreads/906406/ ventilators-donated-by-elon-musk-cant-used-coronavirus-patients-health-officials-say BiPAP machines made by ResMed ••••••••••••••••••••••••••••••••••••••••••••••••••• www.washingtonpost.com/world/the_americas the university started mass production in July https://www.the-scientist.com/news-opinion/colombian-engineers-ventilators-to-be-tested-in-covid-patients-67696 COLUMBIA Omar Ramirez, La Sabana University Los Andres University and the University Hospital of the Pontifical Xavierian University https://ebom.com/covid-19-ventilator-crisis/ COVID-19: We Have The Ventilator Blueprint! https://www.bbc.com/news/technology-52251286 Coronavirus: Raspberry Pi-powered ventilator to be tested in Colombia human trials at the beginning of May timeline reflects the urgency with which Colombia's authorities are treating the matter https://interestingengineering.com/this-coronavirus-ventilator-runs-on-raspberry-pi-but-must-pass-tests-in-colombia-before-use https://www.usnews.com/news/health-news/articles/2020-04-16/colombia-rushes-to-make-cheap-ventilators-for-covid-patients https://www.hackster.io/news/an-open-source-ventilator-powered-by-raspberry-pi-and-arduino-goes-into-testing-in-colombia-6c3f04b1ca94 ••••••••••••••••••••••••••••••••••••••••••••••••••• https://f1000research.com/articles/9-218 Apr 30, 2020 A review of open source ventilators for COVID-19 and future pandemics ChicagoTribune 2020May6 s1p7 Fermilab ventilator DavidHeinzmann Stephen Brice, physicist, Fermilab Christiano Galbiati, physicist, Italy Italians found out that pressure control was critical Mechanical Ventilator Milano component cost <$1,000 https://www.bbc.com/news/technology-52251286 Coronavirus: Raspberry Pi-powered ventilator to be tested in Colombia human trials at the beginning of May timeline reflects the urgency with which Colombia's authorities are treating the matter https://www.bbc.com/news/technology-52251286 Marco Mascorro, a robotics engineer https://www.newsbreak.com/news/1545916169435/coronavirus-raspberry-pi-powered-ventilator-to-be-tested-in-colombia https://www.newsbreak.com/channels/computer-code https://www.newsbreak.com/news/1546239047221/raspberry-pi-boards-are-being-used-to-build-ventilators https://cacm.acm.org/news/244347-raspberry-pi-powered-ventilator-to-be-tested-in-colombia/fulltext Columbia's University Hospital of the Pontifical Xavierian University and Los Andes University https://www.reddit.com/r/CoronavirusUS/comments/g0im0s/ventilator_ran_on_raspberry_pi_and_common_parts/ https://patient-innovation.com/post/3425 https://www.hackster.io/news/an-open-source-ventilator-powered-by-raspberry-pi-and-arduino-goes-into-testing-in-colombia-6c3f04b1ca94 https://hackster.imgix.net/uploads/attachments/1100341/image_W9JzJa1B9S.png?auto=compress%2Cformat&w=740&h=555&fit=max https://github.com/Mascobot/pandemic-ventilator-2.0 https://www.youtube.com/watch?v=ZqtTlJ4bQYw&feature=youtu.be https://hothardware.com/news/raspberry-pi-ventilator https://www.neowin.net/news/a-raspberry-pi-powered-ventilator-will-soon-be-tested-in-colombia/ https://science.slashdot.org/story/20/04/13/166218/raspberry-pi-powered-ventilator-to-be-tested-in-colombia uses only easy-to-find parts https://www.sciencedaily.com/releases/2020/06/200624100041.htm June 24, 2020 Source: University of California - San Diego built around a ventilator bag usually found in ambulances http://friend.ucsd.edu/madvent/ minimal susceptibility to supply chain disruptions https://www.wired.com/story/plaintext-for-open-source-ventilators-making-them-is-the-easy-part/ https://www.discovermagazine.com/technology/how-to-build-a-mechanical-ventilator-for-a-few-hundred-euros https://www.propublica.org/article/taxpayers-paid-millions-to-design-a-low-cost-ventilator-for-a-pandemic-instead-the-company-is-selling-versions-of-it-overseas- https://www.bbc.com/news/uk-scotland-north-east-orkney-shetland-52343759 Aberdeen University space team develops ventilator fully working prototype quick and cheap enough to build for nations with underdeveloped healthcare system ATMO-Vent (Atmospheric Mixture Optimization Ventilator).
