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.
Kami melihat ruangan dengan ventilasi alami di mana rumah sakit mengijinkan kami mematikan ventilasi mekanis di bagian sayap gedung dan membongkar jendela yang tidak digunakan lagi, namun ruangan ini digunakan dalam kajian kami.
