While arterial blood sampling remains the gold standard, end-tidal carbon dioxide (EtCO2) monitoring is a noninvasive surrogate measurement used to estimate PaCO2 values. In acute TBI care setting, data generally showed only moderate correlation between PaCO2 and EtCO2 and agreement < 50% (defined as PaCO2-EtCO2 ≤ 5 or 6mmHg). Several concurrent conditions leading to V/Q mismatching were identified to further undermine the reliability of EtCO2 as a PaCO2 surrogate, such as severe chest trauma, hypotension, and pediatric acute respiratory distress syndrome. Transcutaneous partial pressure of carbon dioxide (PtcCO2) monitoring is another proposed surrogate for PaCO2; its application in adult severe TBI did not show superiority over EtCO2 monitoring. More research is warranted to evaluate the utility of PtcCO2 monitoring in severe TBI care. |
