The patient with which of the following assessment findings meets the criteria for beginning weaning from PEEP?
A) PₐCO₂ = 85 mm Hg; FɪO₂ = 0.6; Cₛ = 20 mL/cm H₂O; PEEP = 12 cm H₂O
B) PₐCO₂ = 100 mm Hg; FɪO₂ = 0.9; Cₛ = 22 mL/cm H₂O; PEEP = 10 cm H₂O
C) PₐCO₂ = 150 mm Hg; FɪO₂ = 0.7; Cₛ = 25 mL/cm H₂O; PEEP = 12 cm H₂O
D) PₐCO₂ = 95 mm Hg; FɪO₂ = 0.3; Cₛ = 30 mL/cm H₂O; PEEP = 15 cm H₂O

The criteria for initiation of weaning from PEEP include: (1)an acceptable PₐO₂ (90 mm Hg)on an FɪO₂ 0.4; (2)hemodynamic stability; (3)absence of sepsis; (4)improved CL (e.g.,CS > 25 mL/cm H₂O); and (5)PₐO₂/FɪO₂ ratio > 250 to 300.Choice "A" does not meet the minimum PₐO₂ or the minimum FɪO₂ and has a low Cₛ.Choice "B" has the appropriate PₐO₂,but the FɪO₂ is high and the Cₛ is low.Choice "C" has a high PₐO₂,but the FɪO₂ is 0.7,the calculated PₐO₂/FɪO₂ ratio is 214,and the compliance is just at the acceptable level.Choice "D" has all acceptable criteria,including a calculated PₐO₂/FɪO₂ ratio of 317.
