A 67 year old male is admitted to the intensive care unit secondary to a COPD exacerbation, requiring Bipap support. As the AGACNP, on afternoon rounds you notice the patient is more lethargic than this morning. An ABG is ordered. ABG Results: pH 7.20, CO2 88, O2 56, HCO3 23. You decide that intubation and mechanical ventilation is the most appropriate next step. After intubation a chest x-ray is ordered to confirm placement of the endotracheal (ET) tube. Where is the correct anatomical position of the ET tube?
