This case involves a middle-aged woman who passed out during a marathon. EMTs responded and intubated the patient before transporting her to a nearby hospital. After arrival at the hospital, it was determined that the patient had been intubated into the esophagus. The tube was then removed and the patient’s oxygen saturation began to rise, however she had suffered significant hypoxic brain injuries. It was later determined that the patient would likely have recovered without significant medical intervention by EMTs.
