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.
