Hello, this is the podcast Surgery I see rounds. My name is Dr. Jeffrey Guy.

I'm an associate professor of surgery and director of the Burns Center at the Vanderbilt University School of Medicine in Nashville, Tennessee.

Over the past several years, namely since the results of the ARDSNet study, there's been a large emphasis placed on the value of peak

inspiratory pressure, which we often will say PIP in the ICUs.

And what the data the ARDS net study showed was that by maintaining an adequate peak

insipatory pressure that we're able to reduce mortality

in the management of ARDS.

And I don't really want to get in this

podcast as to what

the findings of the ARDS net

are, but I really want to focus on that one

particular value and it's peak

statutory pressure. For those residents that I have, they know that I'm

kind of a nut about physiology and I love equations and part of the

reason why I enjoy physiology and the equations that are helped us to

derive some of these numbers from both cardiovascular physiology and

pulmonary physiology is they give us a better understanding

of what is the result of that number

and how the patient's pathophysiology, their disease,

impacts that number, and what can we do clinically

to manage the patient to get us to a more desirable location,

whether it's managing the stroke volume or their pulmonary capillary wedge pressure,
