A physician orders 2 L/min O2 through a simple mask to a 33-year-old postoperative woman with moderate hypoxemia breathing room air (PaO2 = 52 mm Hg). What would be the correct action at this time?

a. Carry out the physician's prescription ex-actly as written. b. Recommend that the mask be changed to a cannula at 2 L/min. c. Recommend a flow of at least 5 L/min to washout carbon dioxide (CO2). d. Do not apply the O2 until the medical di-rector has been contacted.

A patient being ventilated with APRV has the following settings: Phigh = 24 cm H2O; Thigh = 5 sec; Plow = 4 cm H2O; Tlow = 1 second, FIO2 = 0.3

The patient's spontaneous respiratory rate is 10 breaths/min. The current arterial blood gas values are: PaO2 = 91 mm Hg; PaCO2 = 62 mm Hg. What should the respiratory therapist recommend for this patient? a. Increase the Plow to 5.5 cm H2O. b. Decrease the Tlow to 0.5 sec. c. Increase the Phigh to 40 cm H2O. d. Decrease the Plow to 0 cm H2O.
