[Possibilities and limits of pulse oximetry for monitoring anesthesia in horses].
In this paper the measurement technique pulse oximetry is examined in 25 halothane-anaesthetized horses. Furthermore measures are presented which lead to a successful sensor placement at the tongue of the horse. The hemoglobin saturation determined by the pulse oximeter (SaO2) correlated very well with the hemoglobin saturation calculated by blood gas analysis (sO2). Nevertheless in the range of low saturation the pulse oximeter increasingly overestimates sO2. Pulse oximetry is an important progress in equine patient monitoring. A decline of oxygen saturation in the blood is detected immediately and the registration of the pulse amplitude renders a rough estimation of the quality of peripheral perfusion.
