Summary SpO2 values from the Nonin 8600V veterinary pulse oximeter, using a lingual clip-type, transmittance sensor applied to the tongue, were compared to directly-measured SaO2 values from a co-oximeter, calibrated for equine blood, in 5 halothane-anesthetized horse. Normocapnia was maintained with controlled ventilartion. The inspired oxygen concentration was varied by mixing nitrogen in oxygen to obtain SpO2 readings of approximately 60, 65, 70, 75, 80, 85, 90, 92, and 100%. At the time of each SpO2 recording, an arterial blood sample was collected for immediate analysis of SaO2. A total of sixty paired measurements were made. The results showed excellent data correlation with a bias (precision) of 0.55 (2.57) and an R-value of 0.98 over the entire SaO2 range tested. Based on these findings, the Nonin 8600V veterinary pulse oximeter, with the lingual sensor, performed accurately and reliably, and appears to be suitable for clinical use in anesthetized horses.
