Comparison of Simultaneous Capillary Blood Gases and End-Tidal Carbon Dioxide in Mechanically Ventilated Pediatric Patients with Acute Respiratory Failure

Abstract

In the follow-up of ventilation, invasive blood gas analysis and noninvasive monitoring of end-tidal carbon dioxide (ETCO₂) are used. We aimed to investigate the relationship between capillary partial pressure of carbon dioxide (PcCO₂) levels and ETCO₂ and also to investigate ETCO₂'s predictive feature of PcCO₂ levels. This study included 28 female and 30 male pediatric patients; 28 patients were type-1 respiratory failure (RF), 16 patients were acute respiratory distress syndrome, and 14 patients were type-2 RF. Our results showed a significant correlation between ETCO₂ and PcCO₂. Although the strength of the correlation was weak throughout the measurements, the strength of this correlation increased significantly in type-2 RF.
