Figure 2From: Central venous-to-arterial carbon dioxide difference as a prognostic tool in high-risk surgical patientsTrends in PCO2 gap and lactate level. (A) Trends in PCO2 gap (mmHg) and (B) trends in lactate level (mmol/l) in patients who did (n = 78; square markers) and did not (n = 37; circle markers) develop postoperative complications.
