An intubated patient with no known history of congestive heart failure is in the ICU
The patient is comatose and currently receiving mechanical ventilation via volume-controlled continuous mandatory ventilation (VC-CMV), set rate 12 breaths/min, set tidal volume (VT) 400 mL, positive end-expiratory pressure (PEEP) 18 cm H2O, fractional inspired oxygen (FIO2) 0.35, and the patient is not assisting. Hemodynamic measurements show the following: central venous pressure (CVP) 5 mm Hg, pulmonary artery pressure (PAP) 33/20 mm Hg, and pulmonary artery occlusion pressure (PAOP) 16 mm Hg. Arterial blood gas (ABG) results are: pH 7.43, arterial partial pressure of carbon dioxide (PaCO2) 38 mm Hg, arterial partial pressure of oxygen (PaO2) 90 mm Hg. The physician asks for recommendations to improve this patient's hemodynamics. The most appropriate recommendation for this patient is which of the following? a. Initiate pressure support ventilation (PSV) 10 cm H2O with CPAP 10 cm H2O, and check cardiac output. b. Decrease the PEEP incrementally and re-check hemodynamic measurements. c. Change to volume-controlled synchro-nized intermittent mandatory ventilation (VC-SIMV) with the same settings, and recheck hemodynamic measurements. d. Change to pressure-controlled continuous mandatory ventilation (PC-CMV), peak inspiratory pressure (PIP) 25 cm H2O, PEEP 18 cm H2O, FIO2 0.35, and check PAP.
