A 28-year-old female (55-kg IBW)is being mechanically ventilated with VC-CMV,f = 14/min,V_T = 700 mL.The patient has no history of pulmonary disease.The resulting ABG values are: pH 7.55,PaCO₂ 27 mm Hg,HCO₃^- 23 mEq/L.The most appropriate action to take is which of the following?

The original volume setting exceeded the maximum V_T for this patient.The V_T should be set between 275 mL and 440 mL to achieve 5 to 8 mL/kg IBW.Therefore,the V_T must be reduced to avoid overdistention.Using the formula: Desired V_T = 11ea68f7_d69e_2346_b0a4_cbb443a63eff_TB1877_11 Desired V_T = 473 mL The V_T of 450 mL is closest to the desired V_T and is more in line with the acceptable range.
