It has become clear that many critical care clinicians are unaware of a common and
important variety of patient-ventilator asynchrony. This phenomenon has no name and
is not described in textbooks, but might be denoted “peak pressure apnea.” All modern
ICU ventilators have the ability to set an alarm for high peak inspiratory pressures,
which can provide useful feedback in the event of circuit occlusions, mucus plugging,
et cetera. However, on the majority of ventilators, this threshold functions not only
as a passive alarm, but as a hard limit: once this number (or a value close to it)
is reached, inspiratory flow will actually cease.
