[Sanitary chemical research on the atmosphere in wards for cardiac patients]

Man passes a greater part of the day-and-night in closed premises. The pollutants of the inside air, in quantity and quality are more various than that of the atmospheric air, which is due to the additional sources of pollution. The investigation performed is part of a complex study and hygienic assessment of the environment in the hospital rooms of two cardiological wards in view of the prevailing contingent of patients with heart diseases and their specific sensitivity to its qualities. The chemical state of the aerial environment was traced according to several basic indices: concentration of CO2, ammonia, total content of organic substances (oxidizable) and some pollutants, migrating from the polymeric materials, used for furnishing of the hospital rooms. The results received show the necessity for strictly following the regime of ventilation, ensuring the indispensable area for each patient and high light for the rooms. In view of economy of time, labour and means it is recommended the determination of oxidizability and content of ammonia in the air to be carried out one daily. It is also recommended to use synthetic polymer materials in the hospital premises subject to enforced sanitary protection, as little as possible.
