Open Access Abstract Introduction Monitoring cardiac output CO may allow early detection of haemodynamic instability aiming to reduce morbidity and mortality in critically ill patients. Continuous cardiac output CCO monitoring is recommended in septic or postoperative patients with high incidences of intra-abdominal hypertension IAH . The aim of the present study was to compare the agreement between three CCO methods and a bolus thermodilution CO technique during acute IAH and volume loading. Methods Ten pigs were anaesthetised and instrumented for haemodynamic measurements. Cardiac output was obtained using CCO by pulse power analysis PulseCO LiDCO monitor using CCO by pulse contour analysis PCCO PiCCO monitor and using CCO by pulmonary artery catheter thermodilution CCOPAC and was compared with bolus transcardiopulmonary thermodilution CO COTCP at baseline after fluid loading at IAH and after an additional .
