Long-term studies of rabbit blood pressure require a reliable method for repeated blood pressure measurements. Ideally, this method would be simple, noninvasive, and accurate over the range of anticipated blood pressures. To facilitate our own studies of rabbit carotid artery graft patency, we have developed a technique for the indirect measurement of systolic blood pressure in the rabbit that utilizes a photoplethysmograph sensor placed distal to an inflatable air bladder positioned over the central ear artery. We have compared measurements obtained with this method to direct measurements of aortic pressure and found a linear correlation.
对兔子血压的长期研究需要一种可靠的方法来重复测量血压。理想情况下，这种方法应该简单、无创，并且在预期血压范围内准确。为了便于我们自己对兔子颈动脉移植物通畅性的研究，我们开发了一种间接测量兔子收缩压的技术，该技术利用放置在位于中耳动脉上方的可充气气囊远端的光电容积脉搏波传感器。我们将用这种方法获得的测量结果与主动脉压力的直接测量结果进行了比较，发现存在线性相关性。
