So the point is, how do I look at the patient independent of just my eyes? And this is where the stethoscope-Ultrasound and hemodynamic monitoring come in.

And the advantage of hemodynamic monitoring is it's continuous.

The mantra should always be continuous, metabolic, non-invasive.

To the extent that we can do all three of those things, there is less complications and more chance to pick up things early on.

We often can't get away with the non-invasive because certain things can't be measured otherwise.

For example, pulmonary hypertension, right heart failure, ARDS, oftentimes you're really stuck.

Yes.
