The high pressure alarm is sounding on a home ventilator. As your partner prepares the bag-valve mask, you quickly determine that no problem exists with the machine itself. As positive pressure ventilation is initiated, you note high resistance to the ventilations and have a difficult time adequately squeezing the bag. Your next action would be to:

A) Set the ventilator rate faster with a greater tidal volume and initiate transport B) Remove the ventilator, apply oxygen via a nonrebreather mask placed over the tracheostomy tube, continue care, and transport the patient C) Not change the ventilator or settings, but rather summon ALS for on-scene backup or en route intercept D) Replace the ventilator circuit with a new one and try using the home ventilator again
