What is the recommended minimum number of air exchanges per hour in the operating room?

10x/hr
15x/hr with 3 exchanges of fresh air
20x/hr
25x/hr with 5 exchanges of fresh air

The correct answer is: 15x/hr with 3 exchanges of fresh air

The recommended minimum number of air exchanges in the operating room is based on maintaining a safe and sterile environment for surgical procedures. The correct choice emphasizes the importance of having at least 15 air exchanges per hour, which is crucial in diluting airborne contaminants, controlling temperature, and humidity. Furthermore, the specification of having 3 exchanges of fresh air is significant in ensuring that the air remains well-ventilated and consists of a proper balance of fresh oxygen, thereby reducing the concentration of potentially harmful particles or fumes in the surgical atmosphere. This ventilation standard helps in minimizing the risk of infection and enhancing surgeon and patient safety. Choosing a standard that suggests either fewer air exchanges or a lesser emphasis on fresh air circulation could compromise these critical aspects of a surgical environment, leading to potential risks during operations. Therefore, the outlined requirement of 15 air exchanges per hour, supplemented by fresh air exchanges, is integral to upholding the quality of air in the operating room and safeguarding health outcomes during surgical procedures.
