A positive pressure room is designed to maintain a higher pressure than the adjacent spaces, which helps to prevent the ingress of contaminants from those areas. This is particularly important in settings such as hospitals, where sterile environments are crucial for patient safety and infection control. The positive pressure is achieved by ensuring that the air flow into the room is greater than the air flow out, thus pushing potential contaminants away from the room and preventing them from entering.

This setup is essential in surgical suites, isolation rooms for immunocompromised patients, and other environments where minimizing the risk of infection is a priority. In contrast, a negative pressure room, for instance, is intended to contain and prevent the escape of airborne contaminants, making it suitable for isolation of patients with transmissible diseases. Understanding the purpose and application of each type of room is crucial for effective infection control and environmental safety in healthcare settings.
