[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. ⋯ 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.

[Animal welfare quo vadis: animal welfare as a constitutional goal?].
From the point of view of a great research centre the introduction of animal protection in the German "Grundgesetz" raises various objections. These refer to principle law political considerations, ethical aspects and the negative influence this circumstance could have on the progress of biomedical research.

[Monitoring of the oxygen saturation of horses during halothane anesthesia using pulse oximetry in the nasal septum].
The use of pulse oximetry for on-line monitoring of oxygen saturation of arterial blood using a probe on the nasal septum is described in the horse. When compared to the results of blood gas analysis an excellent correlation between the two methods for measuring oxygen saturation is found. ⋯ The cause of this discrepancy is not clear but differences in measuring principle, presence of dyshemoglobins and differences in absorption characteristics of hemoglobin are to be ruled out as major contributors. Contrary to findings in several other animal species occasionally double counting of pulse frequency by the pulse oximeter is seen.
