Fresh Air
The High Pressure Experiments That Made D-Day

The hyperbaric chamber is essentially a gas pressure vessel.

Fresh Air
The High Pressure Experiments That Made D-Day

So you're basically inside a scuba tank.

Fresh Air

Now, our scuba tanks at Duke are very fancy.

Fresh Air

We have seven of them all connected together.

So it is like being inside of a little hamster tube village.

And ours can go to either high pressure or low pressure.

But in that process, you have tons of air and gases moving through the piping.

So that's my biggest impression is you're in this enclosed space.

Fresh Air
The High Pressure Experiments That Made D-Day

They're always either circular, spherical, or cylindrical because that's a stronger shape.

And then you constantly have noises.

Fresh Air

You constantly have gas flow as you're pressurizing.

Fresh Air
The High Pressure Experiments That Made D-Day

It gets really hot really quickly.

Fresh Air

As you ascend the other direction, it gets really cold really quickly.

And then you have people on the outside who are monitoring the gas composition in there when you're in an enclosed space to make sure you're breathing safe levels.

So, yes, the biggest sensory takeaway from a hybrid chamber for me is probably the noise.

Fresh Air
The High Pressure Experiments That Made D-Day

Pretty much.

Fresh Air
The High Pressure Experiments That Made D-Day

We have one atmosphere that we breathe.

Fresh Air
The High Pressure Experiments That Made D-Day

That atmosphere of gas we forget about pretty often, but it does sit on top of us all the time.

Fresh Air
The High Pressure Experiments That Made D-Day

Once we go under the water, we have additional atmospheres that essentially get piled on.

Fresh Air

So every 33 feet or 10 meters of your metric is equal to another atmosphere of pressure.
