Why oxygenation matters
Hypoxemia is a common perioperative complication in veterinary anesthesia.
Continuous SpO₂ monitoring enables early detection of critical oxygen saturation levels
and improves patient safety.
The Incidence of Hypoxemia in Dogs Recovering from General Anesthesia
Piemontese C. et al. · Veterinary Anaesthesia and Analgesia
This study investigated the prevalence of hypoxemia during the recovery phase in dogs following general anesthesia. An SpO₂ value below 95% proved to be a reliable indicator of hypoxemia. The results underscore the importance of continuous pulse oximetry during postoperative monitoring.

Retrospective Evaluation of the Impact of Hypoxemia During Thoracotomy in Dogs
Duffee L. et al. · Veterinary Anaesthesia and Analgesia
This study analyzed dogs during thoracic surgery and showed that intraoperative hypoxemia can be associated with increased mortality and longer hospital stays. The results emphasize the importance of continuous oxygen saturation monitoring during complex surgical procedures.

Comparison of Transmittance and Reflectance Pulse Oximetry in Anesthetized Dogs
Nixdorff U. et al. · Veterinary Anaesthesia and Analgesia
This study compared different pulse oximetry technologies and sensor positions in anesthetized dogs. The results show that alternative measurement sites and modern sensors can enable reliable SpO₂ measurements. Especially under challenging measurement conditions, the choice of sensor can be crucial.

Evaluation of Pulse Oximeters in Dogs, Cats and Horses
Matthews N et al. · Veterinary Anaesthesia and Analgesia
This study investigated the accuracy of various pulse oximeters in several animal species. The results showed that sensor placement and device calibration can significantly influence measurement quality. The study is considered an important reference for the clinical application of pulse oximetry in veterinary medicine.
