Pulse oximetry is a valuable tool for monitoring animals during anesthesia and assessing the adequacy of administered oxygen therapy.
To compare the pulse oximeter readings obtained by the Garmin Fenix 5X plus (GF5Xp) smartwatch and transmittance pulse oximetry (TPO) in anesthetized dogs.
Twelve clinical canine patients requiring anesthesia for castration were prospectively enrolled in this study. The animals were premedicated with intramuscular dexmedetomidine at a dose of 5 µg/kg. Anesthesia was induced through intravenous administration of propofol and maintained using sevoflurane. The arterial hemoglobin oxygen saturation (SpO) readings obtained from the tongue using TPO (238 readings) were compared with measurements taken over the lateral side of the tibia using a GF5Xp smart wearable device (238 readings). This comparison was performed using a Bland-Altman plot, where the differences (%) between the methods were plotted against their mean SpO (Gold standard - Device), and the limits of agreement were represented as the mean ± 1.96 times the standard deviation.
The SpO levels in dogs were overestimated by the GF5Xp relative to the readings obtained by the TPO, with the bias of -0.3% (95% CI: -3.1%-2.5%).
GF5Xp may be interchangeable with TPO in dogs. Further studies are required to validate the accuracy of the GF5Xp in non-anesthetized dogs or dogs outside the physiological range.
脉搏血氧饱和度测定法是在麻醉期间监测动物以及评估所给予的氧疗是否充分的一项重要工具。
比较佳明Fenix 5X plus（GF5Xp）智能手表和透射式脉搏血氧饱和度测定法（TPO）在麻醉犬身上所获得的脉搏血氧仪读数。
十二只需要进行去势麻醉的临床犬科患者被前瞻性纳入本研究。动物肌肉注射剂量为5 μg/kg的右美托咪定进行术前用药。通过静脉注射丙泊酚诱导麻醉，并使用七氟醚维持麻醉。将使用TPO从舌头获得的动脉血红蛋白氧饱和度（SpO）读数（238次读数）与使用GF5Xp智能可穿戴设备在胫骨外侧测量的读数（238次读数）进行比较。这种比较使用Bland-Altman图进行，其中将两种方法之间的差异（%）相对于它们的平均SpO（金标准 - 设备）进行绘制，一致性界限表示为平均值±1.96倍标准差。
相对于TPO获得的读数，GF5Xp高估了犬的SpO水平，偏差为-0.3%（95%CI：-3.1%-2.5%）。
GF5Xp在犬身上可能可与TPO互换。需要进一步研究以验证GF5Xp在未麻醉犬或生理范围外犬身上的准确性。
