Anesthetic gaseous components are necessary to be evaluated in hospital facilities, especially in surgical pavilions. Exposure to anesthetic gases in the health sector, whether in the operating room, recovery room, or in the context of outpatient clinics, may entail a health risk for the personnel exposed. Although health care workers are exposed to much lower anesthetic concentrations than the patients, this exposure often extends over many years. Personnel often indicate fatigue and headaches, especially when occupational hygiene conditions are inadequate. The decisive factors as concerns, the adverse health effects of exposure to anesthetic gases, are mainly the type of gases used, the length of exposure, and the gas concentrations. This paper aims to describe an attempt (successful) to design a sensor control unit in order to improve photoacoustic instrumentation.
