Assess the Following Data Obtained from the Spontaneous Breathing Trials

Assess the following data obtained from the spontaneous breathing trials of four patients.Which patient is most likely to be weaned successfully at this time?

A) Spontaneous rate = 32 breaths/min,V_T = 375 mL,PaO₂ = 98 mm Hg,F_IO₂ = 0.4
B) Spontaneous rate = 15 breaths/min,V_T = 450 mL,PaO₂ = 87 mm Hg,F_IO₂ = 0.6
C) Spontaneous rate = 15 breaths/min,V_T = 650 mL,PaO₂ = 91 mm Hg,F_IO₂ = 0.28
D) Spontaneous rate = 12 breaths/min,V_T = 680 mL,PaO₂ = 79 mm Hg,F_IO₂ = 0.5
