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:

Not change the ventilator or settings, but rather summon ALS for on-scene backup or en route intercept

Explanation:

Based on the information provided within the question it can be said that the best next action to be taken would be to Not change the ventilator or settings, but rather summon ALS for on-scene backup or en route intercept. An ALS or Advanced Life Support, is a set of protocols and skills that are used to extend Basic Life Support in order to assist with an open airway and provide sufficient ventilation to an individual who is not breathing correctly, which is the case if the ventilator begins to fail.

the plates spread at mid-ocean ridges (they are divergent plate boundaries) which allows magma to rise through the weakness between the plates. the magma then emerges as lava from the boundary and cools, creating a new crust.
