Heliox

Ketamine can be used also if you're going to, as an induction agent, and as a sedative and as an analgesic if you're going to intubate a patient with asthma and probably would be the first line of choice for that maneuver.

And then finally, Heliox.

Heliox is a mixture of 80% helium, 20% oxygen.

It has, because of the smaller This is my really rudimentary understanding of chemistry, but because of the smaller molecular structure of heliox, it has better laminar flow through the small obstructed airways of the lower lungs, and so you can more effectively perform gas exchange, whereas normal room air or even 100% oxygen has more tendency for turbulent flow and you'd be increased air trapping with that.

Aminophylline is something that has been used in the past, but it's no longer recommended as either a first line or a second line.

... b- I'm breathing ...

Actually, I'm sorry, I'm actually breathing heliox right now.

Heliox? Wh-

Heliox, it's a helium-nitrogen oxygen blend, 'cause we're at, I'm a sat- I'm in saturation right now.

So how long, um, I, obviously we gotta dive ...
