The PCO2 Gaps

Part of the Lessons from the ICU book series (LEICU)


Carbon dioxide is a catabolic product generated during the Krebs cycle under normoxic conditions. As a final product of cellular respiration, carbon dioxide-derived variables could be potentially used to monitor tissue perfusion and to detect the appearance of anaerobic metabolism during shock states.
