Nonspecific prevention of nosocomial infections

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

Theoretical part of the lesson Introductory remarks

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

Hygienic fundamentals of ventilation

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

Sanitary value of carbon dioxide in indoor air

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,

Microbial aerosol phases and their epidemiological significance

Microorganisms are in the air as a microbial aerosol. An aerosol is a system consisting of liquid or solid particles (dispersed phase) suspended in a gaseous (dispersion) medium. In a microbial aerosol, the dispersed phase is liquid

Determination of indoor air exchange

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
