  1. Precision standard deviation of mean difference between SaO2 and pharyngeal SpO2 measurements, accuracy is root mean square of bias and precision, sensitivity: percentage of times that the pharyngeal SpO2 detect hypoxemia, specificity Specificity is the percentage of time the device does not alarm when there is no desaturation, mild hypoxemia SaO2 < 90- 80%, severe hypoxemia SaO2 < 80%
