Can low-cost, open-source ventilator designs help save lives? – MIT Technology Review

“MIT researchers hope to publish open-source designs for a low-cost respirator that could potentially help Covid-19 patients struggling with critical respiratory problems.

The motorized device automatically compresses widely available bag valve masks, the sort of manual resuscitator used by ambulance crews to assist patients with breathing problems. The designs could arrive as a growing number of engineers, medical students, and hobbyists attempt to build or share specifications for makeshift respirators—of unknown quality and safety—amid rising fears of widespread shortages as the coronavirus epidemic escalates….”
