Calculate and determine the weanability of patients with this data: CD = 25 mL/cm H2O, PImax = 28 cm H2O, PaO2 = 93 mm Hg, PAO2 = 158 mm Hg, and f = 22 breaths/min.

a. 2not weanable
b. 19weanable

Answer to Question 1

ANS: B
Use the CROP formula: CROP = (CD PImax PaO2/PAO2)/f.

Answer to Question 2

ANS: A
The inspiratory drive to breathe is established by measuring the airway occlusion pressure (P0.1 or P100).
