What is the main goal of using positive pressure in operating rooms?

The primary goal of using positive pressure in operating rooms is to prevent contamination. This technique involves maintaining a higher air pressure inside the operating room compared to the surrounding areas. By doing so, the airflow is directed outward, effectively inhibiting the ingress of dust, microbes, and other potential contaminants from outside the room. This is critical in a surgical environment, where maintaining a sterile field is essential for patient safety and the success of surgical procedures.

Through this method, positive pressure also assists in minimizing the risk of surgical site infections, which are a significant consideration in healthcare facilities. It ensures that the air quality remains as pure as possible to protect patients from potential pathogens during invasive procedures.

While maintaining temperature, improving ventilation, and ensuring patient comfort are important aspects of operating room design and function, the primary purpose of establishing positive pressure is focused specifically on contamination control. This rationale is aligned with established standards and practices within the healthcare construction and operational guidelines.
