A patient with ARDS has the slow pressure–volume loop shown below. Based on this loop, at what level should PEEP be set?

What is the optimal PEEP level given the following information? Time 0700 0710 0720 0735 0740 0755 PEEP 0 5 8 10 12 15 P(a-et)CO2 11 10 6 13 15 15 Compliance 26 28 34 30 27 25 BP 138/90 128/93 120/86 100/70 100/70 105/75

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?

A patient with an IBW of 68 kg is intubated and being mechanically ventilated with VC-CMV, f = 12/min, and VT = 470 mL. The patient has a combined respiratory rate of 25/min. The ABG results are: pH 7.56, PaCO2 26 mm Hg, and  HCO 22 mEq/L. The most appropriate action is to do which of the following?
