Indirect blood pressure measurements were compared in 28 conscious cats using Doppler and oscillometric blood pressure-measuring devices. Ten cats were used to compare Doppler measurements between two examiners and 18 cats were used to compare Doppler and oscillometric measurements. The Doppler machine obtained systolic and diastolic blood pressure readings in 100% and 51% of attempts, respectively. With the oscillometric machine, systolic and diastolic blood pressure readings were obtained in 52% of the attempts. With the Doppler, measures of mean systolic blood pressure between two examiners were positively correlated, but there was no correlation for diastolic blood pressure measures. When comparing the results obtained by Doppler and oscillometric machines there was no significant difference between mean systolic blood pressure readings, but the oscillometric machine produced significantly higher estimates of diastolic blood pressure. In both cases, the standard deviations for the oscillometric machine were considerably larger than those for the Doppler machine. The first reading of systolic blood pressure obtained with the Doppler machine was an excellent predictor of the mean of five readings, but this was not so for the oscillometric machine. It took less than 5 min to obtain five readings in 37.5% of cases with the Doppler machine but this was true for only 5% of cases with the oscillometric machine. Two cats with ophthalmological lesions consistent with systemic hypertension were identified. In these two patients, systolic blood pressure measurements were between 200 and 225 mmHg when measured by Doppler, and between 140 and 150 mmHg when measured by the oscillometric machine. This suggests that a lower reference range for normal systolic blood pressure values should be used for the oscillometric device.
使用多普勒和示波血压测量设备，对28只清醒猫的间接血压测量结果进行了比较。10只猫用于比较两名检查者之间的多普勒测量结果，18只猫用于比较多普勒和示波测量结果。多普勒机器在100%的测量尝试中获得了收缩压读数，在51%的测量尝试中获得了舒张压读数。使用示波机器时，在52%的测量尝试中获得了收缩压和舒张压读数。使用多普勒时，两名检查者之间的平均收缩压测量值呈正相关，但舒张压测量值无相关性。比较多普勒和示波机器获得的结果时，平均收缩压读数之间无显著差异，但示波机器对舒张压的估计值明显更高。在这两种情况下，示波机器的标准差均明显大于多普勒机器。用多普勒机器获得的首次收缩压读数是五次读数平均值的良好预测指标，但示波机器并非如此。使用多普勒机器时，在37.5%的病例中不到5分钟即可获得五次读数，但使用示波机器时只有5%的病例是这样。识别出两只患有与系统性高血压一致的眼科病变的猫。在这两只猫中，用多普勒测量时收缩压在200至225 mmHg之间，用示波机器测量时在140至150 mmHg之间。这表明示波设备应采用较低的正常收缩压值参考范围。
