摘要：

The objective of this paper was to evaluate the air quality in three indoor hospital environments: a neonatal intensive care unit (ICU), an adult ICU and a surgical ward of a hospital in Florianopolis, Brazil. Carbon dioxide concentrations, exchange air flow rates as well as fungi and bacteria concentrations were measured in these rooms. Bioaerosol concentrations were evaluated throughout one-work day for each operating room. No relationship was observed between bioaerosol concentration and the period of use in the surgical ward. Average bioaerosol concentrations were of 231 UFC.m(-3) for filamentous fungi and 187 UFC.m(-3) for bacteria. All environments evaluated were, overall, in compliance with current legislations. Results allowed a critical review of the present regulations and suggestions for the establishment of a specific regulation for hospital environments in Brazil.
