Infection control in critical care units

Abstract
Inhalation therapy equipment is a potential vector of gram-negative bacilli. Small-volume Venturi nebulizers have a potential but are infrequently implicated in the dissemination of bacteria. Large volume nebulizers of all designs are the major source for aerosolized bacteria. Ventilators and humidifiers have minimal potential. Any system of decontamination requires the meticulous application of a procedure at least once every 24 hours. The degree of contamination should not exceed that of hospital air.
