A definite diagnosis should be made in the bovine practice field, however, it was difficult to perform laboratory analysis immediately. Currently, three types of portable blood gas analyzers are available in Korea.
This study aimed to evaluate the correlations among these three analyzers.
Seventy-two plasma samples from Holstein-Friesian cows were used for blood gas analysis, and three instruments (EDAN i15 Vet, VETSCAN i-STAT, and EPOC) were operated simultaneously. Moreover, plasma calcium levels were compared between these portable analyzers and blood chemistry device, which is usually used in a laboratory environment. Pearson analysis was performed to confirm the correlation of each parameter produced with the three instruments and blood chemistry analyzer.
As results, high correlation was observed in parameters of pH, pO, potassium ion, ionized calcium, and glucose ( < 0.001, > 0.7). In addition, pCO showed a moderate correlation among the three analyzers ( < 0.001, > 0.5), and there was no correlation among all instruments for sodium ions. There was also a high correlation between ionized calcium from the three portable devices and total calcium from the biochemistry analyzer ( < 0.001, > 0.9).
In conclusion, there was a high correlation between results from the three different blood gas analyzers used in the bovine clinical field in Korea. Thus, a consistent diagnosis can be made even with different equipment if the operator is aware of the strengths and weaknesses of each piece of equipment and operates it properly.
在牛场实践中应明确诊断，但立即进行实验室分析较为困难。目前，韩国有三种便携式血气分析仪。
本研究旨在评估这三种分析仪之间的相关性。
本研究使用 72 份荷斯坦奶牛的血浆样本进行血气分析，同时操作三种仪器（EDAN i15 Vet、VETSCAN i-STAT 和 EPOC）。此外，还比较了便携式分析仪与通常在实验室环境中使用的血液化学设备之间的血浆钙水平。采用 Pearson 分析来确认每个参数与三种仪器和血液化学分析仪之间的相关性。
结果显示，pH、pO、钾离子、离子钙和葡萄糖的参数具有高度相关性（<0.001，>0.7）。此外，pCO 在三种分析仪之间呈中度相关性（<0.001，>0.5），而钠离子在所有仪器之间均无相关性。三种便携式设备的离子钙与生化分析仪的总钙之间也存在高度相关性（<0.001，>0.9）。
总之，韩国牛场临床中使用的三种不同血气分析仪之间的结果具有高度相关性。因此，如果操作人员了解每种设备的优缺点并正确操作，即使使用不同的设备，也可以做出一致的诊断。
