A patient with a tracheostomy tube is receiving positive-pressure ventilation through a volume ventilator. Over the past 5 min, the peak inspiratory pressure has risen, and the pressure limit alarm is now sounding. On quick examination, you notice a generalized decreased in breath sounds. Which of the following problems is most likely?

Question

Quizplus · Accepted Answer

A spontaneously breathing patient with partial airway obstruction will exhibit decreased breath sounds and decreased airflow through the tube. If the patient is receiving volume-controlled ventilation, peak inspiratory pressures will rise, often causing the high-pressure alarm to sound; during pressure-controlled ventilation, delivered tidal volumes will fall.
