Comparison of arterial blood pressure measurements and hypertension scores obtained by use of three indirect measurement devices in hospitalized dogs

Abstract

Results of this study suggested that no meaningful clinical comparison can be made between blood pressure readings obtained from the same dog with different indirect blood pressure measurement devices.

Effects of various factors on Doppler flow ultrasonic radial and coccygeal artery systolic blood pressure measurements in privately-owned, conscious dogs

“…Dogs that did not have a tail, had been anesthetized within the previous 12 hrs, or became fractious or intolerant of manipulation were excluded from the study. Participants diagnosed with local or systemic diseases were not excluded, nor were those dogs receiving medications, consistent with previous studies (King et al, 2001; Hsiang, Lien & Huang, 2008; Bosiack et al, 2010; Wernick et al, 2012). Immediately upon entry into the exam room, both the weight and initial heart rate were recorded.…”

“…Currently, the two most frequently used modalities of indirect blood pressure measurement are ultrasonic Doppler flow monitors and automated oscillometric devices. The Doppler flow method has been shown to be more efficient and to generate more precise measurements of systolic arterial blood pressure (SAP) in conscious dogs in a clinical setting (Hsiang, Lien & Huang, 2008; Wernick et al, 2012). Furthermore, oscillometry can underestimate increased SAP and overestimate decreased SAP, resulting in failure to diagnose hyper- and hypotension, respectively (Sawyer, Guikema & Siegel, 2004; Sawyer et al, 1991; Gains et al, 1995; Bodey et al , 1996; Wernick et al, 2012; Vachon, Belanger & Burns, 2014).…”

In addition to the variability that exists between the two methods described above, both the location of cuff placement, as well as the body position of the animal, can significantly affect the accuracy of indirect blood pressure measurements (Bodey et al, 1994; Bodey et al , 1996; Rondeau, Mackalonis & Hess, 2013; Scansen et al, 2014).…”

Principles of Safety Pharmacology

“…Implanted telemetry has the advantage of not requiring acclimation to handling and wearing of a jacket, but time is needed to allow the animals to recover from the implantation surgical procedure. These include the inability to detect small changes in blood pressure, inaccurate blood pressure and heart rate due to stress from restraint, and limitation to a single-point measurement as compared to continuous measurements provided by other methods Wernick et al 2012). Another method under development for measurement of blood pressure is high-definition oscillometry ).…”

Pharmacokinetics and pharmacodynamics (PK/PD) of irbesartan in Beagle dogs after oral administration at two dose rates

“…After each blood sampling, dogs were assessed for the following clinical end points: heart and respiratory rate, mucous membranes colour and capillary refill time (oral mucosa), temperature (rectal) and systolic blood pressure (SBP) by Doppler method (Parks Doppler Ultrasonic Flow Detector System model 811 [NV, USA], equipped by infant flat probe) (Wernick et al 2012). All the measurements were performed by the same operator.…”
