airway pressure release ventilation

This is more of a kind of an advanced topic, um, and probably outside the scope of this video, uh, but there's different modes of mechanical ventilation.

There's volume control, there's pressure control, there's SIMV, there's APRV.

There's all these different types of, uh, mechanical ventilation where you can deliver breaths differently.

Um, and peak pressure is really a discussion, uh, in this context for volume control, which is the most common modality of mechanical ventilation.

We tried some different things on the vent.

Initially it was on bivent, which is like an APRV setting, and then went to the oscillator.

It was on some low dose fennel to support blood pressure.

Eventually went back to the bivent vent settings.

It is often the go-to mode when compliance is terrible and you are trying to prevent further iatrogenic lung injury.

Speaking of complex pressure modes, the review spends time on APRV airway pressure release ventilation.

The mechanics of this mode are fascinating and honestly a bit backward from conventional thinking.

Very backward, yeah.

The difference between P-high and P-low constitutes the driving pressure.

And a key benefit is that the patient can breathe spontaneously at any point in the cycle, though they do it mostly at P-high, since that is where they spend 90% of their time.

The literature specifically notes a highly technical point for managing APRV.

You have to monitor the flow time waveform closely.
