An increase in the frequency of nosocomial infections is caused by a complex of reasons, the main of which are: 1. Creation of large multidisciplinary hospitals with a peculiar ecology, which is determined by: the

Relevance of the topic. Rational ventilation, that is, properly organized air exchange in buildings is one of the most important conditions for ensuring an adequate level of air quality. According to Erisman, “air is the most common

It includes four groups of events: architectural and planning; sanitary facilities; sanitary and anti-epidemic; disinfection and sterilization. Architectural and planning measures are aimed at preventing the spread of pathogens by distance or the so-called. “Black and white” separation of planning

The conditions of a person’s comfort during a long (more than 20-22 hours) stay in closed inhabited premises are largely determined by the air regime of the building. The building’s air mode is the general process

Their managers are responsible for ensuring the sanitary-epidemiological regime in hospital facilities. One of the most important, urgent tasks in modern hospitals is the prevention of nosocomial infections. For the occurrence of an infectious disease, including nosocomial infection, the

Ventilation (air exchange) refers to the change of polluted air in enclosed spaces by outside atmospheric air. For the first time, scientifically substantiated requirements for air exchange in residential premises were proposed at the end of the last century

Specific prophylaxis or immunization is aimed at increasing the resistance of patients and staff to nosocomial infections, it is divided into planned and emergency. Routine prophylaxis or vaccination (active immunization) begins with the newborn period – in

Carbon dioxide is colorless and odorless and therefore not organoleptically detected by humans; it is 1.5 times heavier than air and usually accumulates in its lower layers, including in the zone of human respiration; in significant concentrations,

Air exchange is characterized by ventilation volume and multiplicity. The volume of ventilation is the amount of air introduced (or supplied) into the room within one hour. It is possible to determine both the required ventilation

The epidemiological end of the bacterial dust phase is associated with those types of microorganisms that do not lose viability upon drying. The resistance of pathogenic microorganisms to drying is very different. It is known that in the coarse-grained
