A 56-year-old man presents to the emergency department with a
three-day history of fever, shaking chills, cough, and sputum
production. He was previously in good health and takes only
amlodipine for a history of hypertension. In the emergency
department, his heart rate is 130 beats/min, respiratory rate
32breaths/min, blood pressure 80/40 mm Hg, temperature 38.8°C
(102°F), and oxygen saturation 92% on 6 liters of oxygen by
nasal cannula. Pulmonary examination demonstrates crackles
and bronchial breath sounds in both lower lobes. A chest
radiograph shows multilobar consolidations. Although awake and
alert, he appears visibly distressed and has marked accessory
muscle use. Apart from antibiotics and resuscitation for sepsis,

A 56-year-old man is admitted to the ICU for pneumonia. He is
intubated, with the following settings: assist control, tidal volume
550 mL, respiratory rate 12 breaths/min, positive end-expiratory
pressure 5 cm H2O, FIO2 1.0. Vital signs are: temperature 38.7°C
(101.6°F), heart rate 122 beats/min, respiratory rate 20
breaths/min, blood pressure (BP) 88/46 mmHg, SpO2 97%. A
central venous line and arterial line have been placed. He has
been started on broad-spectrum antibiotics. Which of the following
