Summary

Two pulse oximeters showed clinical usefulness in anesthetized horses, accurately detecting changes in arterial oxygen saturation. While generally underestimating values, they provided reliable measurements at the tongue probe site.

Area of Science:

  • Veterinary Anesthesiology
  • Cardiopulmonary Monitoring
  • Medical Device Evaluation

Background:

  • Pulse oximetry is crucial for monitoring oxygenation in anesthetized animals.
  • Accurate hemoglobin saturation measurements are vital for patient safety.
  • Evaluating device performance across different probe sites is essential.

Purpose of the Study:

  • To assess the clinical utility of two pulse oximeters in horses.
  • To compare pulse oximeter readings with arterial oxygen saturation measurements.
  • To evaluate performance at different probe sites (tongue and ear).

Main Methods:

  • Nine anesthetized horses were included in the study.
  • Hemoglobin saturation was measured using two pulse oximeters (SaOx).
  • SaOx values were compared to saturation calculated from arterial oxygen tension (SaO2).

Main Results:

  • Both oximeters tended to underestimate SaO2, with mean differences of -3.7% (tongue) and -6.0% (ear).
  • Limits of agreement at the tongue were +1% to -8%.
  • Variability increased at saturation levels below 80% and with the ear probe site.

Conclusions:

  • Despite underestimation, pulse oximeters demonstrated clinical usefulness in detecting arterial hemoglobin saturation changes in horses.
  • The tongue probe site offered more consistent results compared to the ear.
  • Further validation may be needed for readings below 80% saturation.
