Results Overview

Looking at the accuracy of CO2 levels assessed via end tidal CO2 (ETCO2), capillary CO2 (Cap-CO2), and transcutaneous CO2 (TCCO2) compared to arterial blood gas (ABG) which is the gold standard.

Measure
Cystic Fibrosis
Cystic fibrosis patients undergoing general anesthesia. End tidal CO2 (EtCO2): End tidal CO2 (EtCO2) is monitored through the endotracheal tube during general anesthesia. Transcutaneous CO2 (TCO2): Continuous and noninvasive real-time monitoring of transcutaneous CO2. Capillary CO2 (CapCO2): Capillary CO2 collected by finger stick and run on the i-STAT handheld blood analyzer. Arterial blood gas (ABG): Arterial blood gas collected from the radial artery and run on the i-STAT handheld blood analyzer.
