Plain-English summary
A group of 122 healthy elderly dogs had their blood pressure measured using two different methods: Doppler and high-definition oscillometry. The results showed that while both devices provided similar average blood pressure readings, individual dogs had significant differences between the two methods. About 46% of the dogs were found to be hypertensive (high blood pressure), and many of these dogs showed lower blood pressure readings when measured at home compared to the clinic. This suggests that some dogs may experience temporary high blood pressure in a clinical setting, which is known as situational hypertension.

Abstract
OBJECTIVE: Agreement of systolic blood pressure measurements (SBP) between noninvasive blood pressure devices in conscious dogs is poorly studied. Situational hypertension is expected in clinics, but studies are lacking. This study aimed to compare SBP measurements obtained with Doppler ultrasonic flow detector (Doppler) versus high-definition oscillometry (HDO) in clinics and at home and to estimate the prevalence of situational hypertension in conscious, apparently healthy elderly dogs. ANIMALS: 122 apparently healthy elderly or geriatric dogs were prospectively recruited. PROCEDURES: Systolic blood pressure was obtained consecutively with Doppler and HDO techniques in a randomized order per dog, following a standardized protocol. An at-home measurement was advised for in-clinic hypertensive dogs (SBP ≥ 160 mmHg), also using both devices. RESULTS: Dual measurements were available in 102 dogs. Median SBP was 147.3 mmHg (range, 105 to 239 mmHg) for Doppler and 152.3 mmHg (range, 113 to 221 mmHg) for HDO. Forty-six percent (56/122) were hypertensive, of which 9% (11/122) were hypertensive with both methods. No significant difference was found between the 2 devices in the global study population or within the group of hypertensive dogs. Repeated at-home measurements were performed in 20/56 (35.7%) hypertensive dogs, resulting in a 10 and 26 mmHg lower median SBP value for Doppler and HDO, respectively (P > .05). In-clinic situational hypertension was presumed in 8/20 (40%) dogs. CLINICAL RELEVANCE: The choice of the noninvasive blood pressure device did not significantly impact SBP results, but large interindividual differences in SBP between techniques occurred. Situational hypertension was frequently observed in clinic.
