This is the case of a 35-year-old man
0:03
who is complaining of chest pain.
0:06
What I like to do when I encounter chest X-rays, which you'll see lots
0:09
of in the emergency room, is to create a checklist of doing the same
0:13
thing every single time, in every single instance.
0:17
How you do it may differ from
0:18
how I do it, but what I encourage you to do is to find a way and stick to it.
0:23
In that way, you don't forget anything.
0:25
So what I like to do is first to take a look at the lung fields.
0:29
I'm looking for any sorts of nodules.
0:31
Any sorts of plural effusions, airspace consolidation, masses, pneumothoraces.
0:37
I'll take a look at the heart and the mediastinum,
0:40
paying attention to the airway as well.
0:43
We'll look at the bones and the
0:44
soft tissues as we move kind of
0:47
out of the periphery of the examination.
0:50
So in this exam, when I look
0:51
at the left lung field,
0:53
normal lung markings, and everything here looks normal, well expanded.
0:57
There's no focal consolidation, pleural effusion.
1:00
When I come to the right side, and it's a little difficult to see,
1:05
but when you magnify, you can see really nicely, the pleural line that's sitting here.
1:13
Not at the edge of the thorax, but this is a pneumothorax.
1:18
What I like to do with pneumothoraces
1:21
is to give clinicians information that they can use.
1:23
And so what that involves is measuring the air gap.
1:28
And so we'll measure here an apical
1:30
air gap, which is approximately 6cm.
1:34
I'll also provide a lateral air gap,
1:38
which is about 3.4cm. And so, we also want to make sure that with pneumothoraces,
1:45
we're giving clinicians additional information that they can work with.
1:49
And so the big thing we want
1:50
to mention is, is there any evidence of tension?
1:53
And so for tension,
1:54
we're looking for shift of the mediastinum structure, so the airway or the heart
1:59
and mediastinum, away from or in the opposite side of where the pneumothorax is.
2:04
So for a right sided pneumothorax,
2:06
we would expect to see things shifting to the left if there was tension.
2:11
And here we can see that the airway is
2:12
still pretty well aligned with the midline spinal structures.
2:16
We also can look at the distance
2:18
between the ribs and there they look
2:20
pretty symmetric on both sides.
2:22
There is no evidence of tension.
2:24
However, we do have a large right sided pneumothorax.
