Abstract:
The quality of compressed medical air which is used in the apparatus (SCBA)1, but in diving apparatus (SCUBA)2 as well, is regulated by the European standard EN 120213. These requirements relate primarily to: permissible concentrations of oxygen, carbon dioxide, carbon monoxide, humidity, odours, and particles of dust and oil vapour. Compressed medical air must meet certain criteria - not to have any flavour or odour. When filling breathing apparatus it should be taken into account that vehicle exhaust gases, vapors of hazardous liquids, smoke and other harmful substances are not in the vicinity of the suction pipe because they may occur inside the bottle/cylinder of SCBA and with their presence disrupt the microclimate (strictly defined parameters of medical air) and directly endanger the user. The breathing process depends on the percentage of moisture in the air (regulates physical stress) and on condensation and freezing during the use and storage as well. Particular attention should be paid to the maintenance and regular servicing of compressors and breathing apparatus, which eliminate the sudden appearance of a system failure.

Key words:
medical compressed air (KMA),breathing apparatus,permissible concentrations,microclimate,physical stress,system failure.
