The Power Of Voting - DAS Ascot 2013

I administered the mobile phone voting system at the DAS Meeting 2013 at Ascot ( and I think all who attended agreed that this type of interactivity added a lot of flavour and stimulation to the discussion of the case presentations.

These are some samples of the results. This first one is from a comparison between the expert panel, comprised of 7 members, and the audience, 140 of whom responded.

Experts & The Audience

This was a case regarding a large wound haematoma secondary to C-spine surgery. The haematoma was anterior to the larynx causing severe narrowing of the airway with stridor. Unfortunately I don't have the CT image from the presentation.

Of the four options (and one "other") the expert panel was split between the two awake options on offer.

The audience, whilst largely agreeing with the experts, gave a wider range of choices with a significant number of people opting for IV induction.

Bear in mind - the audience did not know results of the expert vote prior to voting, all results were only shown after all votes had been cast.

How Lectures Can Change Opinion

An expert on obstetric anaesthesia gave a talk about approaches to GAs in obstetric anaesthesia and the necessity, or not, of RSIs.

Voting was prior to the lecture, with results below.

The same question was asked after the lecture with the following result.

A significant proportion of the audience who voted were swayed by the evidence and experiences presented during the lecture. I found this a particularly interesting utility of easy to use voting systems - gauging the effect of what we teach on the opinions of others.

This was an enjoyable and educational meeting and I must give thanks to Dr Jairaj Rangasami, Dr Mridula Rai, Professor Jaideep Pandit, Dr Subrahmanyan Radhakrishna and Dr Mansukh Popat for having me down for the meeting.

A Small Flood of Apps

ENTSHO, Resus Algorithms 2 and The DAS APP
This last week was pretty busy. I've released a new app, released a new and overhauled version of an app and released a teeny tiny update to another app.
ENTSHO The app is out now for Android and iOS. It's a collaborative production with 
You can find it for download on the Google Play Store and the Apple App Store now. 

This is "Stage 1" of the ENTSHO release - there are three guideline sections but only one is available at the moment. The other two will be released in the next few weeks, as staggered releases. Thereafter the app will updated to reflect the guidelines at
Resus Algorithms 2 The popular Resus Algorithms was getting pretty long in the tooth and, more importantly, was out of date. Resus Algorithms 2 has the Resus Council (UK) guidelines from 2015; the latest versions.
iResus is back from the ether and this time it's by the Resus Council. It's similar but different to R…

Resus Algorithms on Android hits 4500 users

Yes, 4500. That's some type of milestone because it's taken ages for the numbers to rise from about 4300 users. There were a few dips where I lost users but no matter - the point of Resus Algorithms is to get those algorithms into the hands of those that want and need them.

The story on iOS is a little different.

In the Google dev console I can see downloads AND current installs. On iOS I can only see downloads so I've no idea how many people are still using using Resus Algorithms.

On iOS there are 4910 downloads. On Android there are actually 7570 downloads. 3000 people uninstalled Resus Algorithms on Android. Can I accept the same proportions on iOS?

I'm going to assume, for arguments sake, that all 4900 iOS downloads represent users.

The latest NHS numbers, from this link - - state there are 518864 doctors and nurses in the NHS at the moment.

So I have 1.81% penetration of my potential users!

In July 2014…

Anaesthetic Reference Cards

Pre-flight Check

Anaesthetic Reference Cards, a new Subjective Effect app, is out now on iTunes and Google Play. The support site, with instructions, can be found here.

I was approached (electronically, natch) by a consultant anaesthetist who thought the physical cards he'd been involved with producing would make a nice app. He was right. It's a simple app for anaesthetic novices and as such has probably been released too early. When the new intake starts in August perhaps they'll find their way to it. Oh, it's my first Ionic app. More to come.

Ionic and on an on

Speaking of Ionic; I wrote a relatively well received piece over on Medium which is partly intended to be really useful for Ionic beginners and partly my own notes, for me, posted online so I can get to them any time. Have a read.
