➡️ Question
A 70-year-old male patient is intubated and receiving mechanical ventilation in the volume-controlled A/C mode. After performing endotracheal suctioning, which of the following would indicate the effective clearance of retained secretions?
A. An increased tidal volume
B. A decreased inspiratory time
C. A decreased plateau pressure
D. A decreased peak pressure

In general, you should remember that retained secretions will increase the patient’s airway resistance and peak airway pressure during volume-controlled ventilation. So, taking that into consideration, if you were to clear the secretions via suctioning, that should decrease the patient’s peak airway pressure. On the other hand, if the patient had been receiving pressure-controlled ventilation, you would expect an increase in delivered volume once the secretions were cleared. That is the key tidbit that you needed to recognize in order to answer this question correctly. In other words, you needed to understand the difference between volume and pressure-controlled ventilation.
