Summary

THE OPERATION AND EFFECTIVENESS OF A VENTILATING SYSTEM BASED ON A LAMINAR AIR FLOW INTAKE CEILING WERE TESTED IN A MODEL HOSPITAL OPERATING ROOM. THREE SEPARATE SETS OF MEA-SUREMENTS OF GERM AND PARTICLE DISTRIBUTION TAKEN UNDER SIMULATED NORMAL WORKING CONDITIONS SHOWED THAT IT WAS POSSIBLE TO MAINTAIN A PROTECTED SECURE AREA WITH A LEVEL OF GERM DENSITY AS LOW AS ZERO. THE RESULTS CLEARLY SHOW A SIGNIFICANT DIFFERENCE FROM THOSE OBTAINED WITH CONVENTIONAL TURBULENCE-CAUSING INTAKE CEILINGS WITH PERFORATED GRILLES. AN ATTEMPT WAS MADE TO SIMPLIFY TEST PROCEDURES PRESCRIBED IN THE GERMAN STANDARD DIN 4799 FOR VENTILATING SYSTEMS BY CONDUCTING THE TESTS IN THE PRESENCE OF AN ACTUAL SURGICAL TEAM.
