Background The arteriovenous difference of partial pressure of carbon dioxide (PCO2) between mixed or central venous blood and arterial blood is the ∆PCO2 or CO2 gap. Previous data demonstrated a strong relationship between ∆PCO2 and cardiac index (CI) at the very early phase of resuscitation in septic shock. Monitoring the ∆PCO2 from the beginning of the resuscitation may be a useful tool to assess the adequacy of cardiac output (CO) in tissue perfusion. Aim of work: To examine behavior of ∆PCO2 during early management of septic shock. Methodology: Seventy-six patients with diagnosis of septic shock admitted to critical care department, Cairo university hospitals. We classified the study population according to initial resuscitation response, initial CO2 gap, or 28-days mortality. The response vs non-response to initial resuscitation, ICU morbidity and recovery rate were the study primary outcomes while secondary outcomes included ICU length of stay (LOS) and 28-day ICU Mortality.
