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.
