- Abstract
- The indoor air deterioration of health clinics and hospitals has increased by the presence of microorganisms (MO), which are generated by the presence of chemical contaminants in the air and dust particles that are suspended in the air for long periods of time. This causes worsening health of patients and affects people working and visiting their sick relatives. The use of antibacterial filters (AF) has decreased the percentage of MO in these types of environments and has managed to maintain and improve the health of patients, workers and visitors to these hospitals. With the use of AF in the public health clinic and hospitals was reduced the generation of respiratory infections (RI). These filters are exposed to physical agents (dust), chemical (air pollutants, primarily sulfur and nitrogen oxides in Mexicali, where the study was conducted) and microbiological (bacteria and viruses). These contaminants reduce the operational capacity of these filters and generate aggressive environments that infect the main areas where patients are hospitalized, affecting their health. This research study was conducted from 2010 to 2011, and developed in two stages: (1) analysis techniques with scanning electron microscopy (SEM) and Auger electron spectroscopy (AES) to determine the effect of air pollutants that have a greater effect on the deterioration of electrical connections antibacterial filters, which causes operational efficiency declines; and (2) the development of a design and development of an automated system (AS) which detects electronic malfunction filters and indicates the period in which it was necessary to change the filter. With the AS, improved cleanliness levels of the air and rate of RI are decreased in the public health and hospitals and hospitals in this city. The stations with higher rates of corrosion and corrosivity levels (CL) were in summer and winter.
