Hi! Welcome to our video on
We're gonna talk about the types of medications
that make it easier for your patients to breath.
Now let's do a quick review of kinda
how the respiratory system works.
Obviously, oxygen enters through
your nose and your mouth.
So before we even get started, stop
and take a deep breath.
You know that's never a bad
idea when you're studying.
It's always a good idea to come and
take that deep breath and to relax.
If you are able to take a good, deep
breath, don't take that for granted.
Because we're gonna learn today how we
use medications to take care of patients
who can't do that for various reasons.
But let's talk, start from your nose and
your mouth, it travels down the bronchi,
down to the bronchioles and exchanges CO2,
which is a waste product in the body,
exchanges CO2 for O2 at
the alveolar capillaries.
Now those capillaries are pretty fragile because
that's where really cool exchange happens.
When that exchange is compromised, that's
when we need the respiratory medications.
So we've got the smooth muscle, it's found in
the walls of the bronchi and the bronchioles.
So that smooth muscle is part
of what gets us into trouble.
If that smooth muscle constricts, it's like
someone put their hands around your throat.
So I want you to keep in mind that part of
what we're getting use with medications
that open up airways is you want
to relax that smooth muscle.
Because bronchial spasms are when the smooth
muscle just clamps down on those airways
and the patients are
unable to get a breath in.
So that's just a quick review
of the respiratory system.
None of that should be
new content for you.
But first of all, I don't want you to ever take for
granted the ability to take a big, slow, deep breath.
Because that's what our patients with respiratory
problems are desperate to be able to do.
Remember the key players
that you see in the slide.
You've got the airways, you've got the alveolar
capillaries where the CO2/O2 exchange happens.
Because remember, even if a patient is not breathing,
if I was to put my hand over someone's mouth,
prevent them from breathing, CO2 would
still be building up in the body.
So that exchange, CO2 and O2 is
obviously, critically important.
