What is it all about?

‘@CPET_class  and Keeping  CPET Simple’ is an educational blog which runs alongside Twitter.
The aim of this blog is to improve confidence in cardiopulmonary exercise testing (CPET) interpretation, and to encourage more consultants, anesthetists and physiologists in particular,  to ‘have-a-go’.

We will Keep it simple.

The intention of  this site is purely for teaching interpretation of the 9-Panel plot in diagnostic CPET.

Please note – This is an educational site, intended for healthcare professionals and shouldn’t be construed as patient advice.

For the benefit of those who are new, here is brief outline of how the two component sites weave in together. 

The two component sites are:

1. This blog Forum – “www.KeepingCPETsimple.com”

2. Twitter Account      “@CPET_class” leading the interactive discussion thread under #CPETclass

The blog (http://www.keepingcpetsimple.com) assumes a basic knowledge about heart and pulmonary anatomy, the heart’s conducting system, cardiovascular, pulmonary and metabolic pathologies and the views obtained from the 9-panel plot.

@CPET_class Twitter Feed

The Twitter account profile ‘@CPET_class’ is used to launch the case and subsequent discussions, using the hashtag #CPETclass.

A new CPET case “quizz” is launched bi-weekly on Wednesday evenings in term time, via @CPET_class, and a conversation/discussion around the case evolves on #CPETclass during the course of the evening. 

Each term will be divided into 5 ‘classes’ or ‘cases’ to discuss:


On alternate weeks, a summary of the previous week’s interactive Twitter discussion is archived on https://keepingcpetsimple.wordpress.com/ for reflection and review (links provided after each case).

Cases are generally aimed at Primary Care.  All scenarios are completely fictitious, but based on commonly occurring presentations in General Practice.


If joining in on Twitter – please use the Hashtag #CPETclass on Twitter, if you want to ask the patient any questions, or request any further investigations. 

Alternatively, please join in discussion and leave comments below.

Remember there are no right or wrong answers!
CPET interpretation is often open to debate, and will usually evolve and change as new information becomes available.  Everyone’s opinion is valid, and useful for others, as the evolution process takes place.

Together we will try and form an interpretation based on the 9-panel plot, and information, we have in front of us.  Don’t worry if you disagree – shout out and share your thoughts – the diagnosis is often arguable on the basis of a 9 panel plot.

If you feel confident enough to join in, that’s fantastic, but equally its great if you just prefer to watch and learn quietly.

Please feel free to leave any comments on the blog – It’s really helpful to know how many people are ‘out there’, finding this class useful.

The more the better, to bring diversity to the class – So if you feel you’d like to get involved with basic CPET teaching, or have some interesting CPET results to share please do let us know.

You can contact us via e-mail, or DM us on Twitter via @CPET_class.

Please feel free to join in, but most important of all, have fun! 🙂

Thank you.
