Tech in Surgery Prep / Unit 9 TSC 203 short lesson, about 20 seconds
Oxidizers and the Oxygen-Rich Zone
Captions available
The idea
Supplemental oxygen and nitrous oxide make the area around the patient's face and upper body an oxygen-enriched zone.
In practice
The FDA advises the minimum oxygen the patient needs, closed delivery where possible, and clearing oxygen from the field before an ignition source is used.
Where people slip
Risk is highest when an ignition source is used near the oxygen, at the head, neck or upper chest.
