How would you address what is being demonstrated on this flow-volume loop for a mechanically ventilated patient?

A patient is receiving mechanical ventilation with the following settings: SIMV mode, mechanical ventilatory rate = 10 breaths/minute, tidal volume = 450 mL, FiO2 = 60%, PEEP = 3 cm H20. Her PaO2 is 44 torr. What is the most appropriate recommendation?

A decreased urinary output is a hazard of pressure support ventilation.

What is the normal range of mixed venous oxygen pressure (PvO2)?

What is most likely occurring due to these waveforms?

Which of the following is an example of when a respiratory therapist may trigger a manual breath for the mechanically ventilated patient?

A patient is being mechanically ventilated in the SIMV mode with: Mechanical tidal volume of 520 mL Spontaneous tidal volume of 240 mL Mechanical frequency of 4 breaths per minute Spontaneous frequency of 32 breaths/minute Pressure support of 5 cm H20 PEEP of 5 cm H20 100% oxygen Which of the following ventilator adjustments might be most appropriate?  

A doctor asks the respiratory therapist what change could be made with the iron lung in order to increase a patient’s exhaled minute ventilation. Which answer is most accurate?
