To be clinically reliable, blood pressure readings taken in quiet surroundings with good technique from healthy, unstressed subjects accustomed to the procedure, should be reasonably constant between occasions. Apart from changes attributable to age or stress, sustained rises suggest hypertension. Yet it is increasingly realised that arterial pressure shows great short-term lability. Despite this, 'tracking' occurs in groups of humans, i.e. when ranked by blood pressure they tend to maintain their rank order. This paper examines month-on-month variability of arterial pressure, measured by non-invasive oscillometry (Dinamap) in both pet dogs and kennel populations. 'Tracking' occurred and there was also evidence of 'white coat' effects. Heart rate was more variable than arterial pressure and should not be used to reject pressure readings unless changes are extreme. There was further evidence that canine blood pressure rises with age.
为确保临床可靠性，在安静环境中，采用良好技术，对习惯该操作的健康、无压力受试者进行血压测量时，不同测量场合的血压读数应保持相对稳定。除了因年龄或压力导致的变化外，血压持续升高提示高血压。然而，人们越来越意识到动脉血压具有很大的短期变异性。尽管如此，人类群体中存在“血压轨迹现象”，即按血压水平排序时，他们往往保持其相对顺序。本文研究了通过无创示波法（Dinamap）测量的宠物犬和犬舍犬群动脉血压的逐月变异性。发现了“血压轨迹现象”，同时也有“白大褂效应”的证据。心率比动脉血压更具变异性，除非变化极端，否则不应仅凭心率变化来舍弃血压读数。还有进一步证据表明犬血压随年龄增长而升高。
