Effect of Corrective or Palliative Procedures on Arterial to End-tidal Carbon Dioxide Pressure Difference in Pediatric Cardiac Surgery

The normal small difference (3–5 mmHg) between arterial (partial pressure of carbon dioxide [PaCO2]) and end-tidal carbon dioxide pressure (ETPCO2) increases in children with congenital heart disease. The present study was conducted to evaluate the effect of corrective or palliative cardiac surgery on this difference (known as DPCO2)
