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

The minimum recommended number of air exchanges per hour in the operating room is 15. This standard is crucial to maintaining a safe surgical environment. Adequate ventilation is necessary to dilute and remove airborne contaminants, including airborne bacteria and volatile anesthetic agents, which can be harmful to both patients and surgical teams.

The 15 air exchanges per hour allow for effective filtration and turnover of the air in the operating room, helping to reduce the risk of surgical site infections. It also ensures that the concentration of anesthetic agents is kept within acceptable limits, promoting a safer environment for the surgical team and the patient. This guideline is supported by various health and safety organizations to ensure optimal airflow and hygiene standards during surgical procedures.
