Veterinarians have only been able to diagnose systemic hypertension in this population during health checks while animals are under anesthesia. Anesthetic drugs used have the potential to confound results of blood pressure measurements; for that reason, hypertension is diagnosed through validated secondary structural lesions. Recently, bears at the rescue center in Vietnam have been trained for cooperative conscious blood pressure measurements. Using direct arterial catheterization, this study validated indirect blood pressure measurements and then used this indirect method to determine normal ranges of blood pressure measurements in conscious, trained bears. This will allow for early diagnosis of systemic hypertension and improve the ability to evaluate protocols used for treatment. This knowledge will improve the quality of care for the hundreds of bears rescued from the bile industry and for other captive bears worldwide.  \nAbstract  \nAt Animals Asia’s Vietnam Bear Rescue Center (VBRC), 40% of the current population has been diagnosed with systemic hypertension. Systemic hypertension lesions have led to fatal consequences in the form of aortic aneurysm and rupture. Historically, veterinarians were only able to diagnose systemic hypertension by identifying validated secondary structural heart and retinal lesions during annual health checks of anesthetized bears. In 2021, the VBRC began training bears for cooperative conscious blood pressure measurements to increase monitoring frequency and expedite the diagnosis of systemic hypertension in affected bears. The objective of this study was to evaluate a noninvasive method of blood pressure measurement in trained, cooperative Asiatic black bears. Indirect blood pressure measurements, using the oscillometric technique, were validated with direct arterial measurements in nine bears (6 male, 3 female, ages 13–22 years) undergoing anesthesia for annual health checks. Eleven trained bears at the VBRC without secondary lesions of systemic hypertension (6 male, 5 female, ages 7–23 years) were used to develop normal systolic ranges for Asiatic black bears using the indirect technique. Mean blood pressure measurements for this group of trained bears (n = 11) were 180.65 +/− 37 mmHg (95% CI: 126–255) systolic. These results suggest that indirect blood pressures may be a useful tool to monitor blood pressure in cooperative conscious bears at the VBRC.  \nKeywords: aortic aneurysm; Asiatic black bear; bear bile; blood pressure measurement; systemic hypertension; animal welfare; Ursus thibetanus  \n1.
