You have a 70 kg male patient on the surgical floor. He is currently using 50 LPM at 50% high-flow nasal cannula. The patient is in respiratory distress and requires support. The physician asks for your recommendations for the initial ventilator settings.

Calculate the static compliance given the following information: Ppeak 42 cm H2O, Pplat 37 cm H2O, VT 550 mL, PEEP +10 cm H2O, FIO2 1.0, rate 22. 

ABG Interpretations: pH  7.33 PaCO2 66 HCO3  35

In hemodynamic monitoring, catheters may be placed directly in all of the following locations except

Calculate the stroke index using the following data: cardiac output = 4.7 L/min, heart rate = 90 beats/min, and body surface area = 1.7 m2.
