Assessing the outcome of PEEP at levels set above 15-20 cm H2O is best done using which of the following?

b. Pressure-volume loop graphics
c. Pulmonary artery occlusion pressure
d. Central venous pressure measurements
ANS: C
At pressures above 15-20 cm H2O, the compliance measurement is not a good indicator of cardi-ovascular function, and monitoring of the pulmonary artery pressure may be indicated.
