Negative room pressure Wikipedia

Negative room pressure is an isolation technique used in hospitals and medical centers to prevent crosscontamination from room to room. It includes a ventilation that generates "negative pressure" (pressure lower than of the surroundings) to allow air to flow into the isolation room but not escape from the room, as air will naturally flow from areas with higher pressure to areas with lower
