NanoGuided Airflow™( Nano GAF™)  is  the latest addition to Johnson Medical family of innovative products in the surgical and critical care field of providing better  environment for patients and care giver. Aiming at reducing contaminants at the surgical field above the operating table and below the operating light, Nano GAF™effectively reduces the contaminants.

InFrance, SSI  contributes to over 10.5% of total Hospital Acquired Infection (HAI),. Similar result were reflected in an Australian survey, where HAI is the main cause of  hospital operating cost going higher and higher.

Contaminants such as dust particle  from the air, skin shedding from surgical team as well as patients, are the media on which bacterial are carried. Such bacterial carrying particles contaminants will flow with air movement.

Guidelines for operating  theatre airflow over the operating table should be unidirectional and not more than 0.3 m/s (60 ft per minute) to prevent drying up patients wound and discomfort to surgical team over the period of the procedure but at the same time it should be effective in blowing  the "particles(e.g. dust, skin sheddings) away from the surgical field."

Computerised Fluid Dynamic is the advance study of  Laws of Fluid Dynamics to model the airflow, and simulate the distribution of temperature, velocity, particles.

Studies by Southerland(1993) showed the probability of post operative septsis is directly related to the number of  airbourne bacteria that is in the vicinity of the wound. Treating post operative complication can be  very costly, the payback period of  an airflow systems that can control the airflow and reduces infection risk can be short and rewarding in patient care, as concluded by Rosengarten(2001).
