To evaluate a veterinary-specific oscillometric noninvasive blood pressure (NIBP) system according to the guidelines of the American College of Veterinary Internal Medicine (ACVIM) Consensus Statement.
Prospective clinical study.
A total of 33 client-owned cats (20 females and 13 males).
Cats were premedicated with methadone (0.3 mg kg) and alfaxalone (2 mg kg) intramuscularly. After 15 minutes anesthesia was induced with isoflurane (3%) in 100% oxygen by facemask while breathing spontaneously. A 22 gauge catheter was placed in the median caudal artery and systolic (SAP), diastolic (DAP) and mean (MAP) arterial pressures were measured. NIBP measurements were collected by placing the cuff (40% of limb circumference) on the right or left antebrachium. The agreement between the two methods was evaluated with the Bland-Altman methods, and the oscillometric NIBP device was evaluated using the ACVIM guidelines for validation of devices.
Data from 30 of the 33 cats were analyzed. Five paired measurements were taken from each cat, totaling 150 paired measurements. Mean bias (limits of agreements) for SAP, DAP and MAP were 2.7 (-22.7 to 28.1), 0.9 (-22.3 to 24.2) and 1.3 (-20.4 to 23.0). The oscillometric NIBP passed all validation criteria, except correlation which was <0.9 for SAP, DAP and MAP.
The Vet20 did not meet all validation criteria by the ACVIM. However, all criteria except correlation were met.
根据美国兽医内科学会（ACVIM）共识声明的指南，评估一种兽医专用的振荡式无创血压（NIBP）系统。
前瞻性临床研究。
共 33 只患畜猫（20 只雌性和 13 只雄性）。
猫用美沙酮（0.3mg/kg）和阿法沙龙（2mg/kg）肌内预给药。15 分钟后，通过面罩在 100%氧气中用异氟烷（3%）诱导麻醉，同时自主呼吸。将 22 号导管插入中尾状动脉，测量收缩压（SAP）、舒张压（DAP）和平均动脉压（MAP）。通过将袖带（肢体周长的 40%）放在右或左前肢来采集 NIBP 测量值。使用 Bland-Altman 方法评估两种方法之间的一致性，并使用 ACVIM 设备验证指南评估振荡式 NIBP 设备。
对 33 只猫中的 30 只的数据进行了分析。每只猫采集了 5 对测量值，总共采集了 150 对测量值。SAP、DAP 和 MAP 的平均偏差（界限协议）分别为 2.7（-22.7 至 28.1）、0.9（-22.3 至 24.2）和 1.3（-20.4 至 23.0）。除 SAP、DAP 和 MAP 的相关性<0.9 外，振荡式 NIBP 通过了所有验证标准。
Vet20 未通过 ACVIM 的所有验证标准。然而，除了相关性之外，所有标准都得到了满足。
