'It's not fancy, but it works': Mississippi doctor uses garden hose, lamp timer and electronic valve to create makeshift ventilators
Dr. Charles Robertson, a UMMC pediatric anesthesiologist and the mastermind behind the idea, said he set out to make the "absolute simplest ventilator we can build with parts available in any city, you don't need special tools to put together and can be done quickly as the need arises."
Made with "primarily a garden hose, a lamp timer and electronic valve," the ventilator, named the Robertson Ventilator, for less than $100, can be assembled in approximately 20 to 30 minutes, meaning a dedicated team of four to five could produce nearly 100 in a day if needed, he said.
Demonstrating the functionality of the machine at a news conference Tuesday afternoon, Robertson turned on a ventilator hooked up to a mannequin. The mannequin's chest began to rise and fall.

U.S. coronavirus death projection lowered but official warns of 'second wave'
NEW YORK, April 8 (Reuters) - An influential university model on the U.S. coronavirus pandemic on Wednesday scaled back its projected death toll by 26% to 60,000 but a federal health official warned of a second wave of infections if Americans relax "social distancing" practices.
The downward revision in the death toll in the University of Washington model - often cited by U.S. and state policymakers - coincides with comments by some political leaders that caseloads may have reached a plateau in certain areas.
