Q: Supplemental oxygen should be turned off for a few seconds while electric cardioversion is performed?
A) Yes
B) No
Answer: A
Supplemental oxygen is a fire hazard! Turning off supplemental oxygen for a few seconds usually doesn't harm the patients as they already have enough reserve oxygen in dead space (denitrogenation). This mostly applies to patients with a nasal cannula, face mask, BiPAP, etc. Although the risk is very low in intubated patients where oxygen is supplied in a closed tubing, it is recommended to pause the ventilators for a few seconds. Risk is higher when oxygen concentration is equivalent or above 50% or is within 30 cm of applied pads.
