➡️ Question
A 50-year-old male patient is intubated with a size 8 endotracheal tube and is receiving volume-controlled A/C ventilation. Upon assessment, you note that the patient’s cuff pressure is measured at 38 cmH2O. Which of the following would you recommend?
A. Withdraw the tube 1–2 cm and reassess the patient’s breath sounds
B. Recommend reintubation with a smaller endotracheal tube
C. Lower the cuff pressure to less than 30 cmH2O
D. Recommend ventilation via a tracheostomy

To get this one correct, you needed to know the normal values for cuff pressure. And in this case, you needed to recognize that 38 cmH2O is way too high and could potentially be dangerous for the patient. Therefore, your first action should be to lower the cuff pressure to less than 30 cmH2O and then check to ensure there are no leaks. For the TMC Exam, you must remember that the normal range for cuff pressure is between 20–30 cmH2O. In this case, there is no indication to withdraw the tube, and using a smaller tube would only cause the patient’s peak pressure to increase, which is something that we do not want. Furthermore, there is nothing in the question that suggests a tracheostomy is indicated, so we can rule that one out as well.
