Which of the following is the approximate total flow that would be delivered from a 28% venturi mask operating at 12 L/min?

You are caring for a mechanically ventilated patient. Flow is 80, Peak Pressure 40, Pplat 20, VT 500, PEEP 5. The patient is orally intubated with a number 8.0 ET tube and is currently ventilated in PRVC mode. Calculate STATIC compliance:

The “water seal” of a chest drainage system: I. works only when suction is used   II. acts as a one-way valve preventing re-entry of air into the pleural space   III. is only necessary if an “air-leak” is present   IV. presents a resistance to exhalation

Which of the following ABG values would be considered normal in a patient with known severe COPD? All values are pH, PCO2, PO2, and HCO3.

24. Calculate the PAO2. Given: FIO2  = 40%      PB = 760      PaO2 = 80          PaCO2 = 78      SaO2 = 95% PvO2 = 40      Hb = 10    PECO2 = 42    VT = 800 ml    f = 12 breaths/min 

Which of the following would you recommend for the above patient?

Before plugging in a fenestrated tracheostomy tube: I. the inner cannula must be installed  II. the cuff must be inflated  III. the cuff must be deflated 

A physician asks you to evaluate a 34-year old male post-operative patient for consideration of IPPB therapy. The clinical goal is to promote deep breathing. Which of the following data would be of most value in determining is IPPB therapy is needed?

24. Calculate the PAO2. Given: FIO2  = 40%      PB = 760      PaO2 = 80          PaCO2 = 78      SaO2 = 95% PvO2 = 40      Hb = 10    PECO2 = 42    VT = 800 ml    f = 12 breaths/min
