Mechanical and Advanced Ventilatory Support Practice Test

An intubated patient is on a transport ventilator. You note the following pressures: Peak Inspiratory Pressure (PIP) is 55 cmH2O, and Plateau Pressure (Pplat), measured during an inspiratory pause, is 25 cmH2O.

You are transporting a 72-year-old female on a ventilator for pneumonia. Her settings are Vt 400 mL, RR 18, PEEP 8, FiO2 50%. The patient, who was previously calm, suddenly becomes agitated, and her respiratory efforts are out of sync with the ventilator's delivered breaths. The high-pressure alarm sounds intermittently.
