What is an indication for increasing PEEP? 

Which ventilator setting adjustment would increase mean airway pressure (Pmean)? 

In what mode of ventilation are all the breaths cycled by flow?   

If a patient is being ventilated with a mode in PC-CMV-CT, but they can’t trigger a breath due to a trigger set too insensitively, how will breaths be triggered? 

Regarding humidification in mechanical ventilation, for which patient population would a heat moisture exchanger (HME) probably be contraindicated? 

A patient with an opiate drug overdose is unconscious and has the following ABG results on room air: pH 7.20; PaCO2 88 mm Hg; PaO2 42 mm Hg; HCO 25 mEq/L. What is the cause of this patient’s respiratory failure? 

A patient on VC-CMV-CT has a set tidal volume of 700 mL and a set rate of 12 breaths/min.  However, she is triggering an additional 3 breaths/min. for a total rate of 15 breaths/min.  What is her minute ventilation? Show your work.  Note: The limit variable (volume)  is not important in this question.  The answer would be the same if the patient is on PC-CMV-CT and getting consistent tidal volumes of 700. 

What is the most appropriate I:E for a patient with highly compliant lungs and increased expiratory airway resistance?

What happens to the isothermic saturation boundary (ISB) when a patient is intubated? 

What is the name of respiratory failure due to inadequate ventilation resulting in elevated carbon dioxide?
