Which of the following are required to have a positive pressure relationship with respect to the corridor?

The positive pressure relationship in certain healthcare settings is crucial for maintaining infection control and ensuring patient safety. The correct choice highlights areas where it is essential to create a positive pressure environment to protect occupants and maintain sterile conditions.

Operating rooms (OR), C-section rooms, and Protective Environments are designed to safeguard patients from airborne contaminants. In an OR, ensuring that the air pressure is higher than adjacent corridors prevents outside contaminants from entering the sterile space. This is particularly critical during surgical procedures where even minor infections can lead to significant complications.

The C-section room similarly requires a positive pressure to reduce the risk of infection for both the mother and newborn during delivery. In Protective Environments, typically used for immunocompromised patients, maintaining a higher air pressure helps keep harmful pathogens from infiltrating the space, providing an extra layer of protection against potential infection sources.

In contrast, other options include rooms that may not necessarily require a positive pressure environment, as their primary function might involve containment, such as isolation rooms or areas meant to manage infectious diseases rather than to maintain sterility. Therefore, focusing on facilities that actively need to prevent contamination from external sources validates why the selected answer is the most appropriate regarding positive pressure requirements.
