Device to Reduce Surgery Site Contamination

Reduction of Airborne Particulate in the Surgical Field Using Directed Local Airflow

The objective of this study is to determine whether the Air Barrier System device reduces airborne particulate and airborne colony forming units present at a surgery site.

The Air Barrier System is a device that uses localized clean air flow to shield a surgery site from ambient airborne contamination. This study examines the hypothesis that the Air Barrier System can reduce the presence of airborne colony-forming units (e.g. bacteria colonies) and particulate at the surgery site.
