Why is there a difference between you measured ETCO2 and PaCO2?

In this episode we talk about this very common phenomenon in anaesthesia, the difference between ETCO2 and PaCO2.

Essentially this all comes down to patient and equipment factors.
BUT the essential element that makes the largest difference is DEAD SPACE.

we discuss the factors effecting it, and the Bohr equation that measures dead space.
