The CDC guidelines state that operating rooms should have 20-25 air exchanges per hour with at least 20% fresh outside air. This helps ensure that airborne pathogens are effectively removed from the OR and the air is constantly refreshed. Using recirculated air without adequate fresh air intake could potentially increase the risk of infections.
