Fevers can be scary—and sudden. But don’t fear: Hosts Dr. Alok Patel and Bethany Van Delft, with the help of Mia the Doll, are here to illustrate how best to …
– Rectal temperature?
– Yeah, they're usually like,
– Let's do it mum.
– No. No.
(playful music)
– Did you know Bethany,
that the most accurate way to
check your baby's temperature
is with a rectal thermometer
which goes in the rectum.
– Yes. I did know, but
do you have any tips,
like the best way to take
a temperature rectally?
Because maybe this is like
exclusive to my children.
None of my babies were ever like,
"Yeah sure. Put that up
there, I'll cooperate."
– They weren't like,
rectal temperature …
– Yeah, they're usually like
– Let's do it mom.
– No. No.
– Just maniac in place.
– Yeah.
– So what's baby's name?
– This is Mia.
This' Mia Baby.
– Mia, Mia Baby.
– Mia Baby
– Mia Baby
– It's Mia Baby.
– Now with one hand, spread the buttocks,
you know where it goes.
You wanna cover that silver
tip at the end of it.
– Okay.
(upbeat music)
– This is what we usually consider
to be the most accurate
way to take a temperature,
especially in young kids
under the age of three months
where a fever could be
potentially serious.
– Beep.
– Beep. Baby doesn't have a fever
'cause she's made of cloth.
And in young, young, young babies,
we strongly advise using a
rectal unless you don't have one.
– If your baby doesn't have a rectum?
– If your baby doesn't have a rectum.
– Then you could use.
– We've got some other
problems to discuss.
So next you said your babies sometimes
don't like to get rectal temperatures.
You can do an armpit temperature,
an axillary temperature.
There you go. Now make
sure you have a good seal.
You're gonna get a beep on this one also.
Now one thing to take note of,
is an axillary or an armpit temperature
is going to run slightly cooler.
– Okay.
– Than the rectal temperature.
And that same thermometer
after you clean it,
can also be used as an
oral temperature as well.
This is obviously harder to do
in younger babies who
aren't gonna cooperate.
Do your kids cooperate
with oral temperatures?
– With nothing.
– [Both] Nothing.
– Nothing on earth.
(laughing)
– But with the kids that do,
make sure your kid bites down.
I'm sorry. Does not bite down.
– Does not bite down.
– But closes his or her
mouth down on thermometer.
– When I was little,
thermometers were glass
with mercury in them.
– Were you little in the 30s'?
– I was little in 1919.
(laughing)
– Bethany.
(laughing)
– She probably doesn't have a fever,
because we've established the
fact that she's not human.
Mia you're human. Shh.
But let's talk about
the second most accurate
way to check a temperature
and that's with a temporal thermometer.
– Okay.
– So ditch that old school oral one.
Temporal.
You're gonna go right in the
middle of Mia's forehead.
She doesn't care. Push the skin button.
You're gonna move along
the middle of the forehead
towards the top of the ear,
stop right at the hairline.
– That's like the easiest.
I can just stick with this,
– A lot of parents do like it.
– All the time.
Now let's say Mia is now six months old,
you can start checking her ear.
– Can we do your ear temperature?
– How do your kids,
– Sure
– Deal with your temps?
– They love this.
They like pushing the buttons
and doing it themselves.
Like they love this.
– They actually love it?
– They love it.
(laughs)
– They're super weird.
– Playtime is take my
temperature in the ear mom.
– Take my temperature in my ear.
– Then you're a pro at this.
You wanna make sure you have a good seal
so you're using the
proper ear thermometer.
What does it say?
– No fever 'cause she's still a doll.
– There's a lot of variation.
You know, children are warmer than adults.
Some people run warmer than
others or circadian rhythms.
There's a weather outside.
That's what your kids was wearing.
What I would again worry about,
is if your kid looks sick,
is acting weird
or if the thermometer is
kinda reading something higher
than 100 range,
check out with your doctor.
– Some people just hot, right?
– Some people just hot.
– Some people just hot.
– Maybe not fever high but like, warm.
– All right.
– There's so many different
types of thermometers
and I know you're all really fascinated
about the physics behind these
little engineering marvels.
I hear you.
So let's run through them,
what they can be used
for and how they work.
First off, the regular
digital thermometer.
Now this uses an electronic heat sensor
to basically measure body temperature.
It can be used in the mouth, armpits
and you guessed it, the rectum.
There's a few pros.
It's fast and it's easy.
It's pretty accurate.
However, if you're trying
to get an oral reading,
it's not as accurate if
somebody has to breathe
through their mouth.
You need to get that good seal.
They also are battery
operated and they can die.
Kinda like this one.
You also have to absolutely make sure
you're keeping them
clean for obvious reasons
when you think about where they go.
You wanna make sure you are using
at least a 60% alcohol based solution.
You can use a dilution of bleach also.
Make sure you're not only
cleaning and disinfecting the tip,
but also the entire
body of the thermometer.
Next up is the exhilarating fascinating
digital ear thermometer.
To accurately measure temperature
inside of an ear canal.
Which is why it's also called
a tympanic thermometer.
Here's how it works.
Every object gives off a little
bit of infrared radiation.
The infrared radiation
coming off the ear canal,
goes back to this thermometer.
It hits something called the thermopile.
That infrared radiation then
gets transferred into heat,
the heat then goes through
an electronic sensor
and you get a temperature reading.
Now there's a few pros of this.
It's quick and it's comfortable.
It's also really cool too.
But a few cons.
It can't be used in really young children,
in their tiny little ear canals
and ear wax can also interfere with you
trying to get an accurate measurement.
Also as always,
you do wanna make sure you
are keeping this thing clean,
and what you wanna do is just
use a little bit of alcohol
or a disinfectant solution
with a cotton ball or a Q-tip
and clean that tip.
But your child is three months old
and you wanna use this really
cool infrared technology.
Huh, you're in luck
because now you have a
temporal artery thermometer.
This is like a forehead thermometer
a lot of people have seen.
It uses infrared technology
to basically take thousands of readings
from the temporal artery,
and it uses all those readings
to give you an accurate measurement.
Obviously this is fast,
it's accurate
and it's really easy to use.
And you can use it on children
as young as three months.
One of the biggest cons however,
is it's pretty expensive.
And as always,
make sure you're keeping
the thermometer clean.
You don't wanna be
using on multiple people
and spreading germs from one
infrared obsessed child to another.
Next step, we have the
alcohol thermometer.
You have to make sure you're
using an alcohol thermometer
designed for humans.
This one is made for a freezer.
Your child is not a freezer.
Now alcohol thermometers basically work
because alcohol expands
when it gets really hot.
You can actually get a measurement
based on the expansion.
Now one downside to it,
which may not affect you,
is that it doesn't give
you an accurate reading
past 172 degrees Fahrenheit.
If any human out there has lived
with a temperature of
172 degrees Fahrenheit,
you're not a human.
(playful music)
– Then there's mercury thermometers,
which are a relic of the past
and now they're like cool
vintage medical tools.
So mercury thermometer
works similar to an alcohol thermometer.
Basically when the mercury
is warm or hot, it expands,
it rises on the tube
and it gives you a
temperature measurement.
Now you should not be using this anymore.
This I should not even be
holding and playing with
because they can break,
the mercury can spill out
and it's toxic.
So in the end, don't take
thermometers for granted.
Not only are they
crucial tools to help you
or a healthcare provider
monitor your child's health,
check for fever,
they're also fascinating
engineering marvels.
And now anytime you go
out, you can talk to people
about how much you know about the physics
of these little fever monitoring devices
and watch yourself get a standing ovation.
But let's say you still
wanna get an accurate reading
using this very cool
infrared technology, voila.
(playful music)
Why aren't you going on? All right cool.
Oh you're in luck.
What the
(beeping)
But you're in luck.
(soft music)
