Key result
Transcutaneous carbon dioxide measurement is not a reliable alternative to arterial blood gas sampling in the acute medical setting.
Why the study?
Arterial blood gas sampling is invasive and carries complications, while arterial lines carry significant risks, creating a need for alternatives to monitor changes in PaCO2 over time in acute clinical settings.

Transcutaneous CO2 measurement cannot reliably replace arterial blood gas sampling for PaCO2 monitoring in acute medical settings.
Transcutaneous CO2 monitoring unreliable for acute PaCO2 assessment; leaves open its role in select stable patients pending prospective validation.
Measurement of the arterial carbon dioxide tension ( P aCO2) is essential in a variety of acute clinical settings and it is often necessary to monitor changes in P aCO2 over time rather than just a one-off measurement. The current gold standard of measuring P aCO2 is arterial blood gas (ABG) sampling but the collection of arterial blood is invasive and associated with complications [1]. To avoid frequent arterial stabs, arterial lines are sometimes placed, but these result in the requirement for level 2 care and are associated with significant risks [2, 3].

Mummery et al. (2019) studied Acute medical setting requiring PaCO2 monitoring. Transcutaneous carbon dioxide measurement vs. Arterial blood gas (ABG) sampling was evaluated. Transcutaneous carbon dioxide measurement is not a reliable alternative to arterial blood gas sampling in the acute medical setting.
