A 190-lb (86-kg), 68-year-old man (IBW = 80 kg) is admitted to the hospital. He is placed on mechanical ventilation for acute respiratory failure compounded by metabolic acidosis. It is determined that he has a renal disorder. The physician orders peritoneal dialysis. In the interim, the physician asks the respiratory therapist to target a pH of 7.35 with assisted ventilation. Initial assessment of the patient resulted in the following ABG: pH = 7.22, PaCO2 = 38 mm Hg, HCO3− = 15 mEq/L, PaO2 = 98 mm Hg on FIO2 = 0.25.The ventilator settings are VC-CMV, f = 24 breaths/min, VT = 600 mL, FIO2 = 0.25.ABG results on this new setting are pH = 7.37, PaCO2 mm Hg = 23, HCO3− = 13.5 mEq/L, PaO2 = 115 mm Hg. A flow-time graphic shows the following: What is the problem, and what would you suggest to correct this problem and still help the patient?
When PaCO2 is elevated (>45 mm Hg) and pH is decreased (

A male patient (83-kg IBW) is intubated and ventilated with PC-CMV, f = 12/min, set PIP = 28 cm H2O, resulting in a VT of 430 mL. The ABG results on this setting are: pH 7.35, PaCO2 45 mm Hg, and HCO 23 mEq/L. Forty-eight hours later on the same settings, the ABG results are: pH 7.54, PaCO2 27 mm Hg, and HCO 21 mEq/L with an exhaled VT of 800 mL. The most appropriate action at this time is which of the following?

A female patient (59-kg IBW) with no history of pulmonary disease is being invasively ventilated with VC-CMV, f = 12/min, VT = 470 mL, PEEP = 5 cm H2O, FIO2 = 0.5. ABG results with these settings are: pH 7.31, PaCO2 54 mm Hg, PaO2 92 mm Hg, SaO2 90%, HCO 24 mEq/L. The most appropriate action for the respiratory therapist to take is which of the following?
