The pulmonologist has asked the respiratory therapist to evaluate a patient for extubation. The patient has the following values recorded:PaO2 of 80 torr on 0.30 FiO2SaO2 of 94%positive gag reflexpositive leak testraises head off pillow upon commandsensorium: alertcoughs deeply when suctionedMEP: 70 cmH2OBased on these findings, what should the RT recommend?

A patient in the MICU who suffered a near-drowning incident is on pressure support ventilation at 20 cmH2O with a tidal volume delivery of 10 mL/kg. The patient has been on this mode for the last 48 hour. When you enter his room, you notice that the patient suddenly exhibits refractory hypoxemia, decrease in lung compliance and tachypnea. A STAT CXR reveals pulmonary infiltrates in all lung fields. Which of the following modes of mechanical ventilation would be appropriate at this time?
