A mode that allows spontaneously breathing patients to breathe at a positive-pressure level, but drops briefly to a reduced pressure level for CO2 elimination during each breathing cycle is also known as:
a. intermittent mandatory ventilation.
b. airway pressure release ventilation.
c. continuous mandatory ventilation (CMV).
d. continuous spontaneous ventilation.

At this level of description, we can avoid the cumbersome verbal ad hoc definition for airway pressure release ventilation such as "a mode that allows spontaneously breathing patients to breathe at a positive-pressure level, but drops briefly to a reduced pressure level for CO2 elimina-tion during each breathing cycle."
