Laminar flow ventilation comprises a continuous flow of highly filtered ultraclean air (UCA) of less than 10 colony-forming units per metre cubed (cfu/m3) of bacteria which is re-circulated under positive pressure into the operating field, with air contaminants generated during surgery being removed.

Ultraclean air ventilation systems produce a vertically directed flow of filtered ultraclean air from the ceiling to the sterile operating area, also known as laminar airflow.
The ultraclean air ventilation system in the operating room consists of a ceiling outlet (2 m x 2.4 m) equipped with a high-efficiency particle air filter (HEPA H14).
On December 11, 2014, a laser counter (Handilaz Mini; Particle Measuring Systems Inc., Boulder, CO, USA) was placed at the usual location of the open chest surgical field 2 m below the ultraclean air ventilation system ceiling outlet with the sampling opening pointing upwards.
Our goal was to substantiate the recently hypothesized transmission pathway of potential pathogens (1,6) from a heater-cooler unit to the surgical field by an airborne route in a cardiac surgical operating room equipped with an ultraclean air ventilation system.
The association of ultraclean air ventilation systems with increased rates of surgical site infections in an epidemiologic evaluation (9) has sparked a debate on the benefit of such systems to prevent surgical site infection in a range of settings for which it has been shown to be effective (8,21-23).
