An MIT team hopes to publish open-source designs for a low-cost ventilator

MIT Technology Review  March 24, 2020
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. They have submitted the device to the FDA for rapid review under an “Emergency Use Authorization.” The team intends to test the devices on pigs in recent days. The MIT E-Vent is anticipated to have utility in helping free up existing supply or in life-or-death situations when there is no other option. About a decade ago a team of students developed a proof of principle version of the machine mainly as a tool for rural areas in developing nations, which have high levels of chronic respiratory issues but limited access to mechanical ventilators. Estimated coast at that time was $100.00. The current team referenced those original designs but made additional efforts to ensure it would be easier for others to reliably make and use the device…read more. TECHNICAL ARTICLE
