目的评价犬、猫和马5个位置的脉搏血氧仪和3个高原血红蛋白饱和度。研究设计前瞻性随机多物种实验。五只健康的狗、猫和马。方法动物麻醉后置入心电导联和动脉导管。采用5 × 5拉丁方形设计，研究了5个位置的脉搏血氧仪（Nellcor Puritan Bennett-395, NPB-190, NPB-290， NPB-40和Surgi-Vet V3304）。在每只动物的三个血红蛋白饱和度平台（98.85和72%）各取10个读数（SPO2）。同时抽取动脉样本，并用共血氧仪测量血红蛋白饱和度。饱和度测量的精度计算为均方根差（RMSD），即偏差和精度的综合，适用于每个物种中测试的每个模型。结果准确度差异很大。在狗中，NPB-395、NPB-190、NPB-290、NPB-40和V3304的RMSD分别为2.7、2.2、2.4、1.7和2.7%。NPB-395, NPB-190, NPB-290， NPB-40和V3304的读数失败分别为0,0,0.7,0,0和20%。舌、趾、耳、唇、包皮或外阴的Pearson相关系数分别为0.95、0.97、0.69、0.87和0.95。在马中，NPB-395、NPB-190、NPB-290、NPB-40和V3304的RMSD分别为3.1、3.0、4.7、3.3和2.1%，而读数失败的比率分别为10%、21%、0%、17%和60%。舌、鼻、耳、唇、包皮或外阴的Pearson相关系数分别为0.98、0.94、0.88、0.93和0.94。在猫中，NPB-395、NPB-190、NPB-290、NPB-40和V3304的所有数据的RMSD分别为5.9、5.6、7.9、7.9和10.7%，而失败率分别为0、0.7、0、20和32%。舌、后爪、耳、唇和前爪的相关系数分别为0.54、0.79、0.64、0.49和0.57。对于饱和度高于90%的猫，NPB-395、NPB-190、NPB-290、NPB-40和V3304的RMSD分别为2.6、4.4、4.0、3.5和4.8%，而失败率分别为0,1.7、0,25和43%。准确性和失败率（未能产生读数）因模型和物种而异。一般来说，在临床相关范围（90-100%）测试的模型中，RMSD范围为2-5%，而V3304的失败率最高。
Objective Evaluation of five pulse oximeters in dogs, cats and horses with sensors placed at five sites and hemoglobin saturation at three plateaus.Study design Prospective randomized multispecies experimental trial.Animals Five healthy dogs, cats and horses.Methods Animals were anesthetized and instrumented with ECG leads and arterial catheters. Five pulse oximeters (Nellcor Puritan Bennett-395, NPB-190, NPB-290, NPB-40 and Surgi-Vet V3304) with sensors at five sites were studied in a 5 x 5 Latin square design. Ten readings (SPO2) were taken at each of three hemoglobin saturation plateaus (98,85 and 72%) in each animal. Arterial samples were drawn concurrently and hemoglobin saturation was measured with a co-oximeter. Accuracy of saturation measurements was calculated as the root mean squared difference (RMSD), a composite of bias and precision, for each model tested in each species.Results Accuracy varied widely. In dogs, the RMSD for the NPB-395, NPB-190, NPB-290, NPB-40 and V3304 were 2.7, 2.2, 2.4, 1.7 and 2.7% respectively. Failure to produce readings for the NPB-395, NPB-190, NPB-290, NPB-40 and V3304 were 0, 0, 0.7, 0, and 20%, respectively. The Pearson correlation coefficients for the tongue, toe, ear, lip and prepuce or vulva were 0.95,0.97,0.69,0.87 and 0.95, respectively. In horses, the RMSD for the NPB-395, NPB-190, NPB-290, NPB-40 and V3304 were 3.1, 3.0, 4.7, 3.3 and 2.1%, respectively while rates of failure to produce readings were 10, 21,0,17 and 60%, respectively. The Pearson correlation coefficients for the tongue, nostril, ear, lip and prepuce or vulva were 0.98,0.94, 0.88, 0.93 and 0.94, respectively. In cats, the RMSD for all data for the NPB-395, NPB-190, NPB-290, NPB-40 and V3304 were 5.9, 5.6, 7.9, 7.9 and 10.7%, respectively while failure rates were 0, 0.7,0, 20 and 32%, respectively. The correlation coefficients for the tongue, rear paw, ear, lip and front paw were 0.54, 0.79,.0.64,0.49 and 0.57, respectively. For saturations above 90% in cats, the RMSD for the NPB-395, NPB-190, NPB-290, NPB-40 and V3304 were 2.6,4.4,4.0, 3.5 and 4.8%, respectively, while failure rates were 0, 1.7,0,25 and 43%, respectively.Conclusions and clinical relevance Accuracy and failure rates (failure to produce a reading) varied widely from model to model and from species to species. Generally, among the models tested in the clinically relevant range (90-100%) RMSD ranged from 2-5% while failure rates were highest in the V3304.
