Apstrakt

Uloga personalizovane ventilacije u zaštiti od mogućih bolesti koje se prenose vazduhom, ispitivana je korišćenjem kapljica od kašlja koju ispušta mašina za simuliranje kašlja, simulirajući ljudski kašalj na različitim udaljenostima (1 m, 1,75 m i 3 m) od korisnika personalizovane ventilacije. Primenjen je model doze i reakcije za neujednačenu, nepotpuno pomešanu sredinu, kako bi se odredilo smanjenje rizika zaraze dvema čestim bolestima koje se prenose putem vazduha. Personalizovanom ventilacijom mogli su se smanjiti vršni nivoi koncentracije aerosola i skratiti vreme izloženosti na svim ispitivanim udaljenostima od ubrizgavanja kapljica. Personalizovana ventilacija bi mogla da smanji rizik od infekcije dvema bolestima, gripom tipa A i tuberkilozom, i to za 27– 65%. Rezultati ove studije prikazuju mogućnost desktop personalizovane ventilacije da smanji rizik od infekcije bolestima koje se prenose putem vazduha.
