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

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

Values are means ± SEM (range). SpO_2origin, pulse oximetry obtained with the original oximetry probe; SpO_2refit, pulse oximetry obtained with the refitted oximetry probe.
