Which of the following quantitative, bacteriological methods of obtaining cultures has demonstrated a significant improvement in the diagnosis and appropriate treatment of VAP?

Using the optimal PEEP study below, determine the most appropriate level of PEEP.  Picture7.png 

For questions 36-39, refer to the following ventilator waveforms generated during PC-CMV: Picture4.1(1).pngPicture4.2(1).png   Approximately, what is the PEF?

Based on the below ventilator graphics, what is this mode? Picture8.png 

A patient has a respiratory rate of 30 breaths per minute and a tidal volume of 300 mL. Calculate the RSBI and determine if the patient is ready for weaning from mechanical ventilation. You must have the correct unit of measurement to get full points.

For questions 36-39, refer to the following ventilator waveforms generated during PC-CMV: Picture4.1(3).pngPicture4.2(3).png What is the most likely interpreation of these scalers?

Refer to the following ventilator waveforms for questions 40-44: Picture5.png What is the VTE?

A patient is on VC-CMV with a set VT of 450 mL. At 1000, you respond to the ventilator alarming. The VTe is 350 mL. While adding the air to the cuff, you hear a hissing sound coming from the pilot line. The most appropriate action to take at this time is to:

A patient has late-onset VAP. Which of the following is correct?

Use the following P-V loop to answer questions 30-33. Picture1(2).png Which of the following is the most accurate estimate of the UIPd?
