Introduction: Assessing of biological quality of air in hospital environments is of particular interest because patients can be a source of pathogenic bacteria for hospital staff, visitors and other patients. It is relevant in specialized care of chronic diseases like cancer, AIDS and organ transplant patients or severe health complications, which require massive intervention for treatment in the operating room and/or intensive care units. To evaluate the influence of environmental factors and intensive care unit occupancy in the concentration of aerobacteria in intensive care units of Fernando Troconis Universitary Hospital. Materials and Methods: Triplicate samples were collected with selective agar for Staphylococcus spp. and Pseudomonas spp. using two-stage cascade impactor located 1.5 m high and constant flow (28.3l/min) for five minutes, locating two stations in each of the three ICU; the collected samples were incubated at 37°C for 48 hours. Environmental factors were recorded with anemometer Kestrel 4500 and occupancy of the unit by manually recording the number of patients and health care personnel of the unit. Results: Maximum concentration was 979.9±31.3CFU/m3 and maximum average 315.6±59.7CFU/m3. Staphylococcus spp. exceeded the concentration of Pseudomonas spp. Maximum intensive care unit occupancy was in adult ICU, higher temperature in pediatric ICU and lower humidity in adult ICU. Discussion and Conclusions: Aerobacteria concentration exceeded values reported by other aerobiological studies in hospital also has little relationship with temperature and little or no with intensive care unit occupancy
