COPD Animation Lecture (nursing care for COPD patient)

Okay, so COPD stands for Chronic Obstructive
Pulmonary Disease. It’s something that you’ re gonna see very often and it s something,
it s a very interesting condition, and we re gonna talk about it. We re gonna tell you
some things that isn t really taught to you in nursing school and isn t talked to you
as a nurse. And unfortunately, because of this, we fail as nurses to provide the best
care that our patients need and we actually put our patients in a very unsafe positions
because we don t fully understand COPD. So, what s COPD is, it s an obstruction of air
flow oftentimes due to emphysema and chronic bronchitis. Okay, so, what happens is, we
have this obstruction of airflow, and most common cause of that is emphysema and chronic
bronchitis. So, what is emphysema? Emphysema is the destruction of the alveoli due to chronic
inflammation and decrease surface area for gas exchange. A common cause of this is smoking.
Okay, so, our alveoli become just destructed or ruined and of course, gas exchange occurs
in the alveoli. So, if alveoli are ruined, we re unable to have that gas exchange, okay.
And then, chronic bronchitis is chronic airway inflammation with a productive cough and excessive
sputum production. So, if, first of all, we have this destroyed alveoli, so, we re not
exchanging gas appropriately, and then we also have this excessive sputum production
and airway inflammation, so, it becomes very difficult for these patients to breathe. Okay, so, let s look at this picture really
quick. Really quickly, so this will be a normal alveoli, here s our bronchiole leading to
our alveoli, and you can see in our normal alveoli, we have plenty of space for air to
exchange. What happens in emphysema, is these alveoli become disrupted and airway or gas
exchange does not happen as it should in a healthy individual. So, the patient is not
able to swap CO2 for O2. And, obviously, because of this, they re going to have higher levels
of CO2, okay? So, what would happen in here? Normally is we have all these CO2 from our
blood, right? And so, the CO2 is gonna pass through here, and what s gonna happen is,
we re gonna push O2 into our bloodstream and we re gonna take the CO2 out and of course,
CO2 is gonna go out as we expire. But, what happens with emphysema, is because they have
these destroyed alveoli, the gas exchange is not happening as it should. And so, CO2
is remaining in the blood stream whereas, you know, an O2 is not being moved into the
blood. So, because of that, the patient has elevated CO2 levels, and what happens is,
is they become accommodated to that elevated CO2. Okay, they have this mismatch of oxygen
or the oxygen isn t perfusing this much. Mismatch isn t gonna be cute, right? And so, we re
gonna get into that a bunch later. But then, what happens with bronchitis here is you can
see this inflammation occurs, and then what happens is, we also have all these excessive
mucus production. So, already, they re not able to exchange gas as they should, but they
also have this excessive mucus production, which makes them even harder for them to breathe. Hey, guys, it s Jon from Thanks
for stopping by and checking out our youtube channel. Be sure to subscribe to find out
all of our new videos as they come out. Listen, nursing school does not have to be so hard,
that s why I created When I was in nursing school, I became so frustrated
with administration that just didn t seem to care, professors that didn t know the content
or just read the powerpoints and so many other problems. So, NRSNG was created to give you
the tools, the support, and the guidance and the community that you need as a nursing student
to accomplish your goal of becoming a nurse. Nursing is awesome. In my time as a nurse,
I worked as a charged nurse, a preceptor, I m an RN, a CCRN, and I ve done so much with
my career. And I wanna give back to you guys. So, be sure to subscribe, check out the free
book down below, 140 must know meds and be sure to check our the other videos that other
students have found very helpful. You guys, thank you so much for stopping by. You can
do this. Nursing is an awesome career, and I hope to see you around.
