* Critical Care MCQ? A 50-year-old woman intubated 7 days for pneumonia and severe sepsis is being evaluated for weaning from mechanical ventilation. Current ventilator settings include volume-assist mode with a tidal volume of 450 mL, rate of 12/min, FIO2 of 0.35, and PEEP of 5 cm H2O. She has stable vital signs, off sedative or vasoactive drips and is awake and able to follow simple commands. Her hand grip is weak bilaterally, lungs are clear, and heart rate is regular with no murmurs or gallop. She received SBT with continuous positive airway pressure for 3 minutes, during which time her RR is 25/min with an average tidal volume of 350 mL, and a NIF measured at –30 cmH2O. An ABG study is pending. Q: Which of the following is the most appropriate action regarding this patient’s weaning from mechanical ventilation? A) Patient should not be extubated as she is likely to fail extubation. B) Patient should be placed on pressure support ventilation of 5 cmH2O for 120 minutes. C) Patient should be extubated at this point without further action. D) Patient should be extubated and placed on non-invasive ventilation. E) Patient should be extubated based on ABG results.
