Abstract Introduction Some guidelines to prevent ventilator-associated pneumonia VAP do not establish a recommendation for the preferential use of either heat and moisture exchangers HMEs or heated humidifiers HHs while other guidelines clearly advocate the use of HMEs. The aim of this study was to determine the incidence of VAP associated with HHs or HMEs. Methods A randomized study was conducted in the intensive care unit of a university hospital involving patients expected to require mechanical ventilation for 5 days. Patients were assigned to two groups one group received HH and the other group received HME. Tracheal aspirate samples were obtained on endotracheal intubation then twice a week and finally on extubation in order to diagnose VAP. Throat swabs were taken on admission to the intensive care unit then twice a week and finally at
