00:00:00.625 --> 00:00:01.757
This is a peak flow meter.

00:00:01.977 --> 00:00:04.547
It measures your peak expiratory flow.

00:00:04.868 --> 00:00:09.861
So, seated is absolutely fine for
using your peak flow meter.

00:00:09.886 --> 00:00:14.180
You want to be seated upright,
legs uncrossed, feet flat on the floor,

00:00:14.205 --> 00:00:19.411
shoulders down,
just sort of tuck your shoulders down

00:00:19.436 --> 00:00:25.172
and hold it so your fingers aren't
obstructing the wee doodad [small gadget].

00:00:25.197 --> 00:00:27.150
Then you're going to take
a maximal breath in

00:00:27.175 --> 00:00:30.280
the biggest breath in
you can possibly take,

00:00:30.312 --> 00:00:32.616
pop it in your mouth and
then force it out.

00:00:32.641 --> 00:00:35.313
And what we're measuring is
that first punch out of air.

00:00:35.338 --> 00:00:37.776
We often say that to patients,
it sort of gives them

00:00:37.791 --> 00:00:41.746
a bit of a visual for working
out what to do.

00:00:43.808 --> 00:00:45.823
We'll just see what
my peak flow is.

00:00:49.262 --> 00:00:51.291
450, that's not so flash.

00:00:51.316 --> 00:00:54.076
So it's best of 3.

00:00:54.091 --> 00:00:56.028
The third one's seldom the best one

00:00:56.059 --> 00:00:58.669
because people are often a wee
bit fatigued by that point.

00:00:58.692 --> 00:01:01.760
But there's a bit of coaching required
when you're doing a good peak flow.

00:01:01.785 --> 00:01:03.570
You'll see the pea-shooter

00:01:04.897 --> 00:01:07.411
and you see that quite a lot.

00:01:07.436 --> 00:01:09.281
People think they'll get a better
reading,

00:01:09.306 --> 00:01:10.451
it's like a test,

00:01:10.476 --> 00:01:12.359
you'll get a better reading
if you do it like that.

00:01:12.384 --> 00:01:15.932
So the main things that you're
coaching is that maximal breath in

00:01:15.957 --> 00:01:19.512
and then just
absolutely honk it out. So...
