The operation room is the clean room with the highest cleanliness and hygiene criteria in a medical facility. The biggest threat to the patient when in the operation room is an infection he/she may contract during operation (according to the Lidwell Study from 1980 that inspected more than 7500 operations in 19 hospitals). At the end this factor can profoundly affect his/her rehabilitation process after the surgical procedure.
In general we define two different types of operation rooms: first is for less demanding operations and the second for high-risk operations. The two types differentiate on the size, type and quantity of air feed to the operation room.
When taking into consideration all the hygiene standards and rules regarding medical tools, equipment and staff it is usually the staff, who conduct the operation, who are the most likely possible source for an infection of the patient. This is prevented by installing an effective ventilation system that ensures a so-called 'clean zone' in which all the staff and the instruments are located during the operation itself. The ventilation system creates an air-shower-like-effect, removing away any impurities generated during the operational procedure.
Since some analyses show that an additional factor that effects the possibility of a patient's contraction are the suits worn by the surgical team staff, the latest trends in the field of operation room solutions include compliance with the CFU – Colony Forming Unit regulations.
