And I was out there as a volunteer.

That's a completely volunteer run chamber.

So, yeah, I'm actually happy to give that a shout out because they do run on donations.

But I was out there volunteering to treat diving accidents.

And we had a diver that came to us because he had...

Either accidentally or something happened during the ascent, but he had an air embolism, which is what happens when you don't exhale properly.

And the air expands as you go up and it can rupture your lungs and travel into your body.

A lot of the times these can be fatal.

If they're not properly treated and quickly, they can have very serious negative consequences.

And this gentleman was a man who had experienced an air embolism.

He was brought to our chamber and we repressurized him.

And once he got under pressure, he just kind of woke up.

He had gone in blue.

And I'm not exaggerating.

This was not a human skin color.

And I will always remember how he looked.

It was this deep bluish purple.

And he went in and the bubble shrank under pressure and he returned to normal.

And by the time he left, he was not only walking and talking, but perhaps more importantly, breathing in with a heartbeat.

The most important similarity is the difficulty of the environment, not just on the human body, but on any instrumentation you want to bring in when you're doing research.
