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?

Question

Quizplus · Accepted Answer

The patient is ready to wean and can be placed on synchronized intermittent mandatory ventilation (SIMV)to allow some ventilator breaths but also allow the patient to breath spontaneously.The pressure support will help to overcome the increased airway resistance of the small endotracheal tube,due to the nasal intubation.The positive-end-expiratory pressure (PEEP)will maintain oxygenation and keep the alveoli open.
