Avaliação da qualidade do ar em ambientes interno hospitalar : ênfase ao centro cirúrgico de um hospital geral do Vale do Rio Pardo, RS.

Abstract

Air pollution is directly related to the evolutionary process, as well as ambient air quality is intrinsically linked to health. In the specific case of the health institutions, the air quality can exert direct influence on the recovery time of patients, the rate of absenteeism of workers and the occurrence of hospital infections. Since the main purpose of a hospital is the provision of quality, efficiency and effectiveness services, critical areas should receive special attention. The care provided in the operating room, given the degree of invisibility of surgical and anesthetic procedures and the consequent reduction of organic defenses, makes this moment main determinant for the occurrence of infection in following surgery procedures. Faced with this scenario, the study was developed in a general hospital, located in Vale do Rio Pardo in the state of Rio Grande do Sul, Brazil, in order to assess the air quality of the rooms of the operating room. An evaluation of comfort parameters, microbiological and chromatographic analysis of the filters constrained devices was carried out. For the analysis of the results was considered the activities performed in the operating room and the potential impacts on air quality.. It was found that the main aspects related to air quality in the hospital under study are met. However, there is the need for structural change in the system of air conditioning in operating rooms in order to reduce the possibility of contamination by atmospheric and the environment CO2 concentration.
