A patient, who is nasally intubated, due to facial surgery, has been successful on her spontaneous breathing trial.
She currently has moderate hypoxemia, despite a fractional inspired oxygen (FIO2) of 40 and positive end-expiratory pressure (PEEP) of 5 cm H2O while on volume-controlled continuous mandatory ventilation (VC-CMV). The most appropriate ventilator mode for this patient is which of the following?
a. Airway pressure release ventilation (APRV)
b. Continuous positive airway pressure (CPAP)
c. Pressure support ventilation (PSV) with positive end-expiratory pressure (PEEP)
d. Intermittent mandatory ventilation (IMV) with pressure support ventilation (PSV) and positive end-expiratory pressure (PEEP)
Question 2
A dual control mode provides pressure-limited ventilation with volume delivery targeted for every breath. If the desired volume is not met the ventilator will volume cycle. This describes which of the following ventilator modes?
a. Airway pressure release ventilation (APRV)
b. Pressure augmentation (Paug)
c. MMV
d. Pressure-regulated volume control (PRVC)
