Own the Oxylog 3000!

If you’re a doc or nurse in Australasia and you take care of critically ill patients chances are you’ll be familiar with the Oxylog 3000. This is the workhorse many of us use to ventilate transported patients, whether it be to the CT scanner and back, or half way across the continent.

You may be familiar with it, but can you ‘own’ it?

George Douros, an Emergency Physician from the Austin Hospital in Melbourne — and the excellent EDteaching.com — has created these useful charts (partly inspired by Scott Weingart’s ‘Dominating the Vent’ talks: part 1 and part 2) to help you ‘own the Oxylog® 3000’. They can easily be cut in half, stuck together and attached to the machine or be used as posters to jog your memory.

This is the guide for pressure controlled ventilation:

And this is for volume controlled ventilation:

If you’re a little hesitant about playing with the knobs when the oxylog’s attached to a real person, George has reminded the LITFL team that there is a pretty cool online simulator that you can play around with on the Drager website.

Finally, as much as we love the Oxylog® 3000, we suggest you read Take a big breath in… and hold it so you don’t get caught out by the lack of an oxygen disconnect breakthrough alarm…

Addendum 7 Sept 2011
There have been a few comments about how to measure plateau pressure using the Oxylog 3000. Here is a diagram from the user manual showing exactly what plateau pressure is (in volume-controlled ventilation IPPV (CMV) mode):

plateau pressure

When an inspiratory pause is present, you can measure the plateau pressure. If there isn’t an inspiratory pause, you can press the inspiratory hold key to create one (keep holding it down)

If you’re not quite ready to own the Oxylog yet, start with the basics in this great video by Jo Deveril and ‘borrow the Oxylog 3000‘ first!

    Thanks Chris for this awesome post. I love it. I am out on remote clinic duty now in Lockhart River in Cape York and the nurses here asked me to give an inservice on their new emergency ventilator, the Oxylog 3000. so it’s great to find this resource on LITFL!

    It’s the main tranposrt vent with RFDS QLD so I will point all my RFDS colleagues to this post!

    How do we do the Inspiratory Hold Manouevre to get the Plateau pressure (the button above the main switch)? Do we just hold for a second and get the reading?

    Thanks for this post.

      From the Oxylog 300 manual:
      Press key »Insp. hold« for as long as inspiration is required.
      Oxylog 3000 will either extend the momentary automatic ventilation stroke accordingly or start a new ventilation stroke and hold it for up to max. 15 seconds.

      You have to press on the »Insp. hold« until it plateaus (a few seconds is usually sufficient) -- give a go on the online simulator.

    No-one where I work measures Pplat. In fact, when I mention it they just look at me as if I am a bit wierd (but I get that a lot). Anyway, I may be wrong about this (I’ve never done it in real life) but I thought to get Pplat you hit the values button until “Pplat” appears in the measured values window and then hit the curves button untill the Paw curve appears in the curves window. Then if you hit inspiratory hold, you can either read the value of the curve (the pressure will drop and plateau) or simply read the value for Pplat. You can try this on the on-line simulator.

    Also there is a great tutorial on the oxylog 3000 at http://www.aic.cuhk.edu.hk/web8/download.htm

      We should be keeping an eye on the plateau pressure in ventilated patients -- it is the best indicator of alveolar pressure which is more likely to correlate with barotrauma than peak inspiratory pressure (which also reflects airway pressure: airway pressure = flow x resistance + alveolar pressure). I’ve added a post on high pressure alarms in the ventilated patient (and which pressures to look at, and why) to the related links in the above post (I’d forgotten about that one!)

      Also,as the diagram I’ve added shows, if there is an inspiratory pause phase then you can just read off the Pplateau value -- otherwise press on inspiratory hold to create one.

      Great tip with the link to Charles Gomersall’s tutorial -- as you’ll see from the pulmonary puzzle blogposts I like his stuff!
