Negative pressure rooms are an essential part of many medical and research environments, as they help maintain clean conditions and prevent the spread of contagious diseases. In these rooms, air is pumped out of the treatment zone, creating a space with negative pressure. This means that when the door is opened, potentially contaminated air or other dangerous particles from inside the room will not flow to uncontaminated areas. Positive pressure rooms, on the other hand, maintain a higher pressure within the treated area than that of the surrounding environment.
This means that air can leave the room without recirculating. The air that is pumped out of the affected space passes through a series of three filters, which end in a HEPA (special high-efficiency air) filter, providing the same degree of filtration as an N95 mask. In order to ensure that a negative pressure room is functioning properly, a smoke capsule or tissue is placed near the bottom of the door; if smoke or tissue passes under the door, the room is negatively pressurized. Additionally, it is important to check for negative pressure daily while being used to isolate tuberculosis patients and once a month if not used for these types of patients.
When constructing negative pressure rooms, it is important to consider the overall integrity of the room and ensure that the negative pressure to corridor ratio is maintained. Highly sensitive mechanical devices, electronic devices, or pressure gauges must be used to ensure accurate measurements. Efficiently installed positive and negative pressure rooms make the difference between a healthy environment for hospital patients and one compromised by infectious pathogens. It is essential to understand how these rooms work in order to keep patients safe from infections and diseases. Negative pressure rooms are an invaluable tool in medical and research settings.
