The study is aimed at investigation of respiratory gases propagation in snow. The study involves volunteers breathing into the snow whereas concentrations of gases are measured at various positions in the snow.
The study is aimed at investigation of respiratory gases (oxygen and carbon dioxide) propagation in the simulated avalanche snow. The study involves volunteers breathing into the snow whereas concentrations of gases are measured at various positions in the snow. A special apparatus was created for sampling and measurement of gas concentrations and to assure stable geometry of the experiment required for data evaluation.

The length of breathing
Time to termination of the breathing experiment due to the decision of the tested subject, or determined by high end-tidal carbon dioxide value or by the order by the clinician assessing the health status of the subjects.
Time frame: Continuously within up to 20 minute interval from the beginning of the breathing experiment
