You have just intubated a 65 year old woman with sudden respiratory failure. On arrival, she had a pulse but cool extremities. She was obtunded and agonal with SpO2 was in the high 70′s. After pre-oxygenating with BVM to 100%, the intubation went smoothly. You had a clear view of the cords and passed a cuffed 8-0 through easily with qualitative capnography and bilateral breath sounds. Now, post-intubation, her SpO2 is 86% and steadily dropping.
Your attending doubts your skills and wants to have a peek at your tube.
