Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

European Resuscitation Council 2021 Guidelines and Advanced Life Support Provider Courses teach that the oxygen supply must be removed from the patient during defibrillation to the distance of minimum of 1 meter. Scientific articles describe few incidents of fire during defibrillation in oxygen - enriched atmospheres.

The study aims to performed a series of measurement of the oxygen concentration in the environment around the patient with different airway management used and ventilation provided.
