A patient receiving mechanical ventilation via pressure-regulated volume control (PRVC) has a set target volume of 500 mL with an upper pressure limit setting of 35 cm H2O

The respiratory therapist should do which of the following? a. Switch the patient to pressure support ventilation (PSV). b. No action should be taken. c. The set volume should be reduced. d. The upper pressure limit should be re-duced.
