Okay, now is the chance to test your memory. What's the average percentage of oxygen in
room air? What do you got? Right. It's 21%. So hopefully you're in breathable room air right
now and you're breathing in about 21%. Now, how do you know how many liters of oxygen
your patient is receiving? I will never forget the first time they told me to put a patient on
4 liters of oxygen. I wasn't even exactly clear on how to do that. They did a research study
and they found out that several healthcare professionals were also unclear about exactly how
to do that. Now we're going to talk about the flow meter and the black ball. So see the flow
meter there, that's the entire piece of equipment you see in that graphic, but look down there
toward the bottom. There's a little black ball in there. Now when you turn on the oxygen,
there's a little knob usually on the front and you turn that knob and that little ball will start to
float higher and higher. So that will indicate to you how many liters of oxygen you're giving
the patient. So in there, a little black ball will float and on those lines are numbers. That
indicates the number of liters that's being delivered to the patient. Now the problem came with
the healthcare professionals. Some looked at the top of the ball, some looked at the bottom
of the ball, but actually the correct way to do this is at the middle of the ball. So use that
knob to adjust the number of liter flow so that the middle of the ball lines up with the
appropriate number ordered liters. Okay? So don't make the same mistakes other healthcare
professionals have made. Be clear, it's the middle of the floating black ball that indicates how
many liters your patient is on. Now let's talk about the ways we control the flow with these
flow meters. See, they can either be inserted directly into wall outlets or the meter might be
attached to a portable oxygen cylinder. Now what you see in the picture is actually a wall
outlet. We'll show you in a minute what a portable cylinder would look like. I want to point out
what a Christmas tree is. Yes, that is the actual name most of us call it. A Christmas tree is
usually green, but I guess it could be any color like the one you see in the picture, but usually
they're green. It's a tree-shaped connector. Now it goes at the bottom of the flow meter and
that's where the oxygen tubing is connected. So, at the top the widest part, that's the part
that we'll screw on to the oxygen meter. As the tree goes down to the point where we would
put the star or the angel that was a real Christmas tree, that's where you connect the
oxygen tubing. Now, a nasal cannula or a mask, all of these apparati will have tubing. So
that's where you would connect it. If I have the flow meter and no Christmas tree, I'm not
going to be able to connect them. So that's what a Christmas tree is used for. Again, I remember
when they asked me to go get a Christmas tree and I just looked at them like "whoaaahhh."
I didn't know what it was. You quickly don't forget that one once you see it. So when you're
making those connections, make sure that connections are tight. I want the Christmas tree on
their snug, don’t try it super clamp it down but make sure it's snug and when you connect the
oxygen tubing same thing. You don't want any leaking because we want to make sure that
we're delivering an accurate amount of liter flow to that patient. Now wall supply oxygen, you
can see the flow meter right there is plugged directly into a special outlet that supplies oxygen.

I want to kind of talk about those outlets. Make sure you read the labels carefully. A lot of
hospitals have them color coated, they're the same in every room, but you want to make sure
that you don't confuse the oxygen flow meter with a medical air outlet. Okay, that's not
going to be oxygen. Medical air is a clean supply of compressed air. We use it for some other
purposes, but we don't use it to oxygenate the patient. We use it in hospitals and healthcare
facilities to distribute other medical gases, but we don't want you to plug and think that you've
got an oxygen meter in a medical air. So just read the labels, you'll be fine. I promise that
will be very clearly labeled in the patient's room. Now, this is a graphic that represents a
portable oxygen tank. Hey this is serious stuff. This is a really scary thing because that oxygen
cylinder can be potentially explosive if it's not handled correctly. So don't ever get in a hurry
and set an oxygen tank down and just leave it there. If that gets knocked over, it could be a
really big problem for everyone. So, oxygen tanks should always be stored in a stand because
you don't want it to tip or to fall. If that happens, that's under extreme pressure. If that tank
is damaged, it becomes like a missile and it could shoot off at a high rate of speed. I mean like
going through a wall high rate of speed. So, you'll actually have to take safety training if
you're employed by a hospital and how to handle oxygen. Because I've never seen it happen,
but the potential is always there. Everyone knows. Never leave the tank free standing, always
have it in a cart, and handle with care. If you're trying to __ a patient and a tank and an
IV, don't do it, get help. Don't do things, you need more equipment than you have hands,
then you need someone to help you move that patient. Now humidifier is optional. You can
connect it to any flow meter and it will help provide some moisturizer to the oxygen. Even low
flow if the patient's wearing it long enough or if they had a high liter, sometimes it can really
dry out their nasal passages. Now, long-term oxygen, we use it if they have a high amount,
those are good recommendations. There are some kind of debate as if it really helps or not but
if it makes your patient feel better consider it. So use it on patients who get high-flow oxygen
or who are going to be on it for longer than 24 hours if they say they are going to feel
some discomfort up here because they're drying out. So small thing, it's not the difference
between life or death but it might make your patient feel much more comfortable.
