0:00.8	Hello, med students.
0:02.5	My name is Zach Olson, and thank you for downloading this week's episode of the EM Clerkship Podcast.
0:11.4	Vents are really intimidating, right?
0:14.8	They're all glowy and beepy and buttony, super intimidating.
0:19.4	But they're actually super easy, so, so easy. It's only going to take
0:24.0	a few minutes today, and you're going to understand how to set up a vent. What you need to know today
0:29.3	are five things, only five things. First, intubated patients in the ED are going to be sedated, vast majority of the time.
0:39.5	And this means that you only need to know one mode of ventilation at first.
0:44.5	One mode, assist control volume.
0:49.7	Now, maybe there is some variation on this globally, and I've seen ICUs put patients on other

1:22.9	But if they over-breathe, it will give them another full volume, assist control volume. It's the most basic
1:29.7	fundamental mode of ventilation, assist control volume, a set volume at a set rate, and if they
1:38.3	over breathe, they get that volume again. It's very, very basic, assist control volume. The second thing that you need to know,
1:48.0	very easy. Venting a patient is like breathing, pushing oxygen in and letting that lung that CO2
1:56.0	vent out. In and out. In and out. you're trying to get that oxygen in with a goal of
2:04.1	92ish percent pulse ox and you are letting that CO2 vent out with a goal on capnography or your
