Okay, we're going to be placing the regulator on an E-cylinder. I have a couple E-cylinders here. This is the standard one that you will be using in the hospital. It is typically color-coded green for oxygen, and you have a little dust cap on it.
here that is utilized to prevent any dust or anything getting in. I'm not going to open this one. I'm going to use the ones that I already have opened.
These were calibration gases off of our PFT machine. They... But the safety system the way they go on is exactly the same.
So I'm saving the tank for class But this is the type you will be utilizing This is called a post neck You will not have to remember the post neck but you do have to remember how to put the regulator on This is an aluminum tank. Does this mean it can go in the MRI? No, it cannot there's steel in here This will fly across the room and get sucked into the MRI. So you do not want to take this You only take MRI approved tanks into the MRI room. If you're unsure, ask the MRI tech.
So this is our typical E-cylinder. I would not suggest lifting with one hand. If you look at this...
See the holes? Those are in the 2 and 5 position. The big hole here is for the oxygen to come out, and you have a dimple on the back for your lock screw. This system utilizes what we call the pin index safety system. Here is the regulator.
You see the lock screw on this side? You screw it in to lock it on. If you look here, there are two pins. The hole for the oxygen is there, the two pins are here, and again you have your bordon gauge.
This is called the pin index safety system or the PISS. You have a fixed orifice, meaning they are preset flows. They go and they're just read them.
They go from 0.12 to 0.5 to 1 liter, 1.5, 2, 3, 4, 6, 8, and on up. You cannot adjust them in between. All you can do is adjust.
Whoop, there we go. 0.5, 1, 1.5, 2, 3, 4, 6, 8, 10, 12, and so on. Now, how do you get this on?
This one's not too bad. You've got to make sure you crack the tank and you again crack the tank. I've already taken this cover off that was on this one, the dust cap. I've already taken it off but I still want to crack the tank.
Okay, that one has a little bit of gas in it. Okay, so I've already cracked the tank. There's a little bit of gas and I want to line this up.
and it sits in. The two pins go into those two holes and then I screw this down. I'll screw it down finger tight and then I can take this and give it a little twist, not a lot, there.
And then I open it. As I can see there's about 200 psi in here. And there is no hissing so I know I have a good seal.
So what I'm going to do is I'm now going to turn this off. So I take this, turn it back off. I bleed the cylinder. It's now empty. And then I take it off.
It's on too tight. How do I get it off? Well, just like that.
This is an E-cylinder with the pin index safety system.
