Evaluation of Gas Propagation in Snow During Breathing of Subjects Under Simulated Avalanche Snow
- Conditions
- Accident Caused by Snow Avalanche
- Registration Number
- NCT05262894
- Lead Sponsor
- Czech Technical University in Prague
- Brief Summary
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.
- Detailed Description
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.
