When the patient stabilizes on mechanical ventilation with a PEEP of 12 cm H2O and the FiO2 has been reduced to 0.40, how should the PEEP level reduce?
a. In increments of 2 cm H2O every 6 hr
b. In increments of 3 to 5 cm H2O every 2 hr
c. In increments of 3 to 5 cm H2O every 1 hr
d. In increments of 5 cm H2O every 2 hr
Question 2
When is the PEEP/CPAP level optimum?
a. O2 delivery to the tissues is maximized.
b. Pressures are maintained below 15 cm H2O.
c. CaO2-CvO2 is maximized.
d. The PaO2 is 60 to 100 mm Hg.
