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? 

The care team and family have decided to transition her to home mechanical ventilation. What strategies would you use to ensure her quality of life while on long-term ventilation (list at least 3 additional parts to your care plan)? 

At 0800 a patient on mechanical ventilation has a peak inspiratory pressure of 26 cmH2O and a plateau pressure of 22 cmH2O. At 1000 the same patient has a peak inspiratory pressure of 31 cm H2O and a plateau pressure of 23 cm H2O. What three things might this indicate, and what corrective actions/interventions could you take for each? What additional waveforms might be useful in helping you diagnose which issue this data presents?
