Table 1 Comparisons of pulse oximetry measurements on the tongue with the original and refitted oximetry probes

From: A preliminary study on the monitoring of mixed venous oxygen saturation through the left main bronchus

Concentration of inspiratory oxygen (%) n Oxygen saturation (%) Correlation coefficient (r)
   SpO2refit SpO2origin  
100 10 100 100 1.0
21 10 93.2 ± 2.4 (92–96) 93.4 ± 2.7 (91–96) 0.95
10 10 81.5 ± 2.2 (77–84) 81.1 ± 2.5 (78–85) 0.94
  1. Values are means ± SEM (range). SpO2origin, pulse oximetry obtained with the original oximetry probe; SpO2refit, pulse oximetry obtained with the refitted oximetry probe.
