OstreaVent I and II (Screenshot from DOSTv Facebook Page) DOST Secretary Fortunato “Boy” T. de la Peña said OstreaVent II was developed by the agency’s Metals Industry Research and Development Center (MIRDC) in partnership with the Breath of Life Foundation Inc. “It can be used by both infant and adult; it is both pressure- and volume-controlled; it measures tidal volume, and it has bacterial and viral filters,” he said during his weekly report on Friday. He noted that the clinical trial for the OstreaVent II “will start as soon.” OstreaVent II used the technology of its predecessor, the OstreaVent I, which is for infant use only, he said.
