Welcome back to the Internet Book of Critical Care Podcast.

I'm here with Adam Thomas and we're going to talk about pulmonary vasulitis and diffuse

alveolar hemorrhage.

This one's going to be a nice little treat coming from the farcass because he trained

in this background.

I learned a lot for this and it's not going to be a long format.

So today we're going to cover

the definition diagnosis, straight up give you the treatment algorithm, and then some pitfalls

and pearls, as always. So Josh, let's get straight into it. Let's overview pulmonary vasculitis

in the ICU. It's either a problem or not a problem. It's hard or it's simple.

This podcast might be a little confusing because we're going to toggle back and forth

a little bit between talking about pulmonary vasculitis and what we're really talking about

predominantly as angovascularitis, which is the most common.

And then other times you're going to be talking about diffuse alveohemorrhmerage in general

and we'll try to be clear about what we're talking about. So we're going to start out with pulmonary vasculitis, predominantly ancavascular So in the ICU, this can present a couple different ways. The most traditional and classic

presentation would be diffuse alveo hemorrhage, folks who are coughing up blood. Unfortunately,

some patients may have diffuse alveo hemorrhage without coughing up blood. They can present simply

with respiratory failure. Another reason that folks may end up in the ICU would be renal failure requirement for emergent hemorrhabilis, and then patients can have a pulmonary renal syndrome where they

have both of these things.

So I'm going to think about organ failure, but the blood vessel is getting in trouble.

Diffuse how velvary hemorrhage, you said.

So a primary pulmonary manifestation, a primary renal manifestation or both together.
