The chest radiograph of an adult patient just placed on HFOV shows the diaphragm at the level of the seventh rib. Which of the following parameters should be adjusted?

A patient with ALI is being ventilated using APRV with the following settings: Phigh = 30 cm H2O; Plow = 2 cm H2O; Thigh = 6 seconds; Tlow = 0.8 sec; FIO2 = 0.4. The patient’s spontaneous rate is 12 breaths/min. The current ABG values are: PaO2 = 61 mm Hg; PaCO2 = 43 mm Hg. What change should the respiratory therapist recommend for this patient?

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 510 mL. The ABG results on this setting are: pH 7.35, PaCO2 45 mm Hg, and HCO3- 23 mEq/L. Forty-eight hours later on the same settings, the ABG results are: pH 7.54, PaCO2 27 mm Hg, and HCO3- 21 mEq/L with an exhaled VT of 900 mL. The most appropriate action at this time is which of the following?

Which of the following is the most appropriate PEEP level for the patient whose information is in the table below?

You are caring for a patient with an IBW of 50kg on the following settings, SIMV/VC, tidal volume 475ml, RR 15bpm, PEEP 5cmH2O, FIO2 0.50. You obtain a blood gas with the following results: ph 7.29, PaCO2 56, PaO2 70, HCO3 26. The physician asks you to make one single change, if needed. What would you do?

Thirty minutes after intubation and initiation of mechanical ventilation, a patient’s PaO2 = 55 mm Hg and the FIO2 = 0.5. To what should the FIO2 be set to obtain to best get a PaO2 of 80 mm Hg?

A 28-year-old female (55-kg IBW) is being mechanically ventilated with VC-CMV, f = 14/min, VT = 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?
