Which of the following therapeutic measures would be the most effective in treating hypoxemia in the presence of intrapulmonary shunting associated with ARDS?
a. Sedating the patient to blunt noxious stimuli
b. Increasing the FiO2 on the ventilator
c. Administering positive-end expiratory pressure (PEEP)
d. Restricting fluids to 500 mL per shift
C
The purpose of using positive-end expiratory pressure (PEEP) in a patient with acute respiratory distress syndrome is to improve oxygenation while reducing FiO2 to less toxic levels. PEEP has several positive effects on the lungs, including opening collapsed alveoli, stabilizing flooded alveoli, and increasing functional residual capacity. Thus, PEEP decreases intrapulmonary shunting and increases compliance.
