Thermoregulatory Reactions of Medical Workers Who Use Personal Protective Equipment From Biological Hazards

Study Overview
=================
Brief Summary
-----------------
This research will provide data on thermal condition, functional status and working conditions of medical workers who use personal protective equipment from biological hazards. Acquired data will be used to define acceptable period of use for these protective costumes.

Detailed Description
-----------------
This research will recruit 14-20 volunteers. During 8 hours each subject will perform their work using protective costume. Heart rate, electrocardiogram, oxygenation, skin and air temperature under costume and hygrometric data will be registered. Also there will be questionnaires for volunteers for subjective assessment of thermal and moisture sensations and assessment of working conditions.
