A 52-year-old woman undergoes facial surgery during general endotracheal anesthesia. The ventilator is set to deliver a tidal volume of 600 ml and a respiratory rate of 10/min at an FiO2 of 1.0. SpO2 is 100%, peak inspiratory pressure is 18 cmH2O, and PetCO2 is 40 mmHg. The surgeon flexes the patient's head so the chin touches the chest. Which of the following findings indicates that endobronchial intubation has NOT occurred?
(A) Fluctuating capnographic waveform
(B) Greater expiratory volume than inspiratory volume
(C) Unchanged SpO2
(D) Unchanged PetCO2
(E) Unchanged peak inspiratory pressure
