End Tidal CO2, or ETCO2 for short, is something that’s talked about pretty often in Emergency and Critical Care and that’s because it’s used a lot in the assessment and treatment of patients!

It’s got a big part to play in airway management, resuscitation, sedation and is also increasingly used in other situations. Some of these applications have some pretty strong evidence to back them up but others are definitely worth a deeper thought, because without a sound understanding of ETCO2 we can fall foul of some traps…

ETCO2 is a non-invasive measurement of the partial pressure of CO2 in expired gas at the end of exhalation. Ideally we’d like to know what’s really going on arterially with the partial pressure of arterial CO2 but we can use the end tidal because that’s an easy reading to get from exhaled breath, when it will most closely resemble the alveolar CO2 concentration.

Its value is reflective of ventilation but also really importantly is affected by the circulation, the circuit and how it’s applied. In the podcast we run through all of these aspects, its application to clinical care and also some of its pitfalls. 

Once again we’d love to hear any thoughts or feedback either on the website or via X @TheResusRoom!

Welcome back to the podcast, a new month, three more papers and discussion around the topics.

We kick off with a paper comparing mechanical ventilation in CPR compared to the more traditional hand ventilation; what difference does the machine make to ventilation in arrest and should we be changing to this strategy as a standard?

We've talked about aneurysmal subarachnoid haemorrhage a fair amount on the podcast and the second paper looks at the effectiveness of lumbar CSF drain compared to standard care with some pretty staggering results!

Lastly we take a look at a paper exploring decision making in prehospital trauma, specifically with regard to blood transfusion. This is a great paper to focus on the complexities of decision making, understand decision making strategies, recognise areas of weakness and consider how aspects of these can be used educationally and to improve emergency care for our patients.

Once again we’d love to hear any thoughts or feedback either on the website or via X @TheResusRoom!
