A 3-D rendering of the Air Barrier System area of protection. The blue shaded part represents a 90 percent or greater reduction in airborne contamination over an area approximately 50.8 centimeters (20 inches) long by 15.24 cm (6 inches) wide. The grey zone represents the 80 percent or greater reduction area.

This short video depicts the Air Barrier System's (ABS) protective "cocoon" effect. The nozzle of the ABS is placed on a mannequin; water vapor (smoke) is delivered onto the simulated surgery area to represent airborne contamination; and a laser shining in a vertical plane is used to visualize a cross section of the ABS area of effect. When the ABS is activated, the viewer can clearly see how it creates a 5-centimeter (1.97-inch) thick clean air field that purges the water vapor. When the ABS is deactivated, the viewer can see how the smoke pours over the incision area.
