So I have this patient with respiratory failure who I am preoxygenating with nasal cannula prior to RSI. I took the cannula off and intubated the patient and he developed ventricular fibrillation immediately afterwards. Code was called and the nurse shocked him. Patient came back to sinus rhythm with the shock but bang at the same time the patient's bedsheets caught fire. Nurses frantically tried to extinguish the fire and then I who was at the head of the bed picked up the sheets and shook them until the fire was extinguished. Turns out the nasal cannula were still on the bed blowing oxygen on the patient and the defibrillator paddles sparked a fire . No harm was done but I was thinking both the patient and me at the head of the bed would have easily been turned into blackened Jamaican Jerk chicken. Beware of nasal cannulas during defibrillation .
