english: We looked at rooms that were naturally ventilated, where the hospital let us turn off the mechanical ventilation in a wing of the building and pry open the windows that were no longer operable, but they made them operable for our study.
non_english: Analizirali smo sobe koje su imale prirodan protok vazduha, u kojima nam je boničko osoblje dozvolilo da isključimo mehaničke ventilacione sisteme u krilima zgrada i silom otvorimo prozore koji nisu bili više u upotrebi, ali su ih oni učinili dostupnim za naše istraživanje.
