8 | |||
9 | VentMon is Public Invention's attempt to build an inline tester and Critical Care Monitor for any Ventilator | ||
10 | |||
11 | This appears to be an oxygen mixer, not a ventilator, but someont should study: | ||

64 | |||
65 | Omar from Colombia | ||
66 | "has built a functional prototype of the Charlotte Valve, developed in Italy, but modified to be built with scuba gear." | ||
67 | |||
68 | |||
69 | Bozhana's group from Resonator.bg has build the Decathlon mask, with a modification for using it as PPE, and it should be tested in a Bulgarian hospital today or tomorrow. She needs visibility on the level of stock of CPAP or sleep apnea machines in Bulgaria to assess her next steps. | ||
