Abstract :
The results of study of a three-component (pH, PaCO2, PaO2) intra-arterial optode in patients undergoing surgical procedures are presented. Twenty-five surgical patients who required radial artery cannulation took part in this study. In each patient, the fiber-optic sensor (0.63 mm in diameter) was inserted into the arterial cannula. Results for the different cannula sizes are analyzed separately. A scatter plot of PoO2 versus PaO2 showing all data from the 18-gauge cannula patients and statistics for the three blood-gas variables and the two cannula sizes are presented and discussed
