Now we're gonna look at the difference
between acute and chronic respiratory failure.
00:06
Now acute means right now, in the moment.
00:09
Chronic means wow, you've had
this problem for a very long time.
00:13
So the body can respond to
acute or chronic more quickly?
Well here's the deal, pretty much no
matter what it is, if it's been a chronic problem,
the body kind of adjust to it
and comes on somewhat slower.
00:28
If it's an acute problem, there's
usually a lot more stress on the body.
00:33
Same thing with respiratory.
00:34
Now acute respiratory failure depending on what the underlying
cause is, might be something that's just short term.
00:41
If we can fix that underlying cause, they'll be okay.
00:44
It usually develops pretty quickly, you need
emergency treatment and other critical care
but hopefully we can resolve an
episode of acute respiratory failure.
00:54
Chronic respiratory failure's ongoing.
00:57
So if I took somebody who has no history of COPD
and they come in and they're in respiratory failure,
I'd expect them to respond pretty quickly but not
to normally have an elevated carbon dioxide level.
01:11
Somebody who's in chronic
respiratory failure, it's ongoing.
01:16
They may live with a higher CO2,
and a lower oxygen level everyday
than the average person
if they have chronic COPD.
01:26
Develops over a longer period of time,
they deal with these issues on a daily basis
and we probably could treat this
patient in a little less intense setting,
maybe a long term care or as an outpatient.
01:39
Now even a chronic respiratory failure
can have some type of exacerbation
and be in acute respiratory failure,
but those are the general differences.
01:48
Acute respiratory failure, it's episodic,
it's short term, develops relatively quickly.
01:53
Chronic respiratory failure's someone who
all the time is dealing with respiratory issues,
ongoing and develops over a longer period of time,
but they do tend to tolerate lower levels of oxygen
and higher levels of carbon dioxide than
someone who's not used to that type of level.
