Advanced Vent Modes - PRVC, APRV, HFOV and MORE!

In this lesson we advance our discussion talking about ventilators as we talk about some of the more advanced vent modes that we have out there. This lesson is meant as a quick overview of these different modes, as future lessons specifically looking at each of these individually will have much more information.

We start off circling back to our understanding of volume control versus pressure control. I talk about the compliance equation and how each of our variables, volume and pressure play in to this equation. Understanding this equation and the difference between these types of ventilation is key really understanding these advanced vent modes.

From there I talk a little about Pressure Regulated Volume Control (PRVC) and how this dual mode ventilation actually works. Next I move on to talk about Airway Pressure Release Ventilation (APRV) a very common and effective mode of ventilation for alveoli recruitment and improved gas exchange. Finally I talk about High Frequency Oscillatory Ventilation (HFOV) or the oscillator. While very common in the NICU with babies, this is still something that we can see used in our adult patients.

Hopefully by the end of this lesson you will have a basic understanding of these various types of advanced vent modes, how they are different from one another, and how it is that they achieve their benefit with our patients.

I’ve been an RT for 29 years, great explanations

[RespiratoryCoach]

Sharing this resource with all of my students! Great, simple break down of these "advanced" modes of mechanical ventilation. Strong work, Eddie! Appreciate the shout out.

[hannahthompson]

Thank you for these! I'm a couple weeks into orientation in the CVICU. I have been totally unable to grasp the concepts behind the various modes of mechanical ventilation despite other nurses' attempts to explain it to me. These videos have literally saved me. It's so understandable if explained well. Now I'm going to go watch your drip videos...

[kyleessex]

I love our videos, I do. I do need to mention for many who may be watching this that it is an important distinction regarding compliance as the the ability to expand and that the force acting to contract is elastance. This is a concept that I have even seen many Physiology PhD's mix up.

So compliance force to expand, and it acts in opposition (Inverse relationship) to elastance or recoil.

This plays a factor in ventilation, perhaps most easily explained with COPD patients. Barrel chesting is associated with an increased compliance with the associated decrease in elastance.

JUST WANT TO SAY THANK YOU FOR THESE VIDEOS AND THE GOOD INFORMATION YOU HAVE PROVIDED I AM THINKING OF GETTING INTO RESPITORY THERAPY AND THESE VIDEOS ARE GREAT INFORMATION TO BE ABLE TO WATCH AND GET EDUCATED. I HAVE WATCHED LIKE 7/8 VIDEOS JUST FOR THE GREAT INFORMATION THAT YOU PROVIDE

[conniera]

I'm an RT student and that was an excellent to the point explanation of those modes. Subscribed. Thank you!

[wa]

Thank you!!! You helped break it down in simple terms, something I haven’t been able to get from anyone yet (including my professors). Thank you!!!

[maddiegirlx]

Thank you so much! I am brand new nurse starting on an ICU floor!

[moritzwolle]

Hello, learned a lot while working on covid icu. It really helped to daily see different stages for ARDS for months... :)

[christinemjs]

I have just started in ICU and I am finding all of your videos very very helpful!! Thank you!

[Lishaaaaaaa]

Oh, you absolute star. This is excellent revision material, especially for someone like me who's a bit poorly atm, so information retention is a struggle.

[MrKir]

You sir are God sent. Extremely helpful for my ICU rotation

[arshadhussain]

Kindly make more videos on ventilators like more advanced modes, ventilator graphics and protocols followed in ICU...these videos are really helpful ! Thanks👍

[gingingsisangag]

Hi! Thank you for this Eddie. Could you pls add a video regarding mech vent alarms

[RossAngeloNegrillo]

Great videos! Would like to ask if you have videos for troubleshooting patient ventilator dyssynchronies? Thank you so much!

[Reyalegro]

Thanks, these videos are really helping me study for my FCCS course!

[akashmaheshwari]

Nice work...the way you have explained the entire ventilator series is amazing 🙌🙌
I have only one Doubt!!.. The PRVC should be volume control as we set the target volume which is needed to be achieved by the the ventilator by adjusting the pressure?
You have mentioned it as pressure control@ 10:08

[karawelch]

Thank you for your AWESOME videos!!! I am and RN starting in ICU this month and am very excited; your videos are easing my nerves. I have a suggestion for a video to make: transvenous pacing. Thank you :)

[laurenguhr]

We use BiLevel alot - sounds similar to APRV

[arseniohardrick]

Thank you Eddie, please keep pumping out the content.
