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

In the follow-up of ventilation, invasive blood gas analysis and noninvasive monitoring of end-tidal carbon dioxide (ETCO 2 ) are used. We aimed to investigate the relationship between capillary partial pressure of carbon dioxide (PcCO 2 ) levels and ETCO 2 and also to investigate ETCO 2 's predictive feature of PcCO 2 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 ETCO 2 and PcCO 2 . Although the strength of the correlation was weak throughout the measurements, the strength of this correlation increased significantly in type-2 RF. Thieme. All rights reserved.
