ABSTRACT
Present clinical study was conducted in 170 apparently healthy dogs for monitoring of blood pressure (Systolic Arterial Pressure: SAP, Diastolic Arterial Pressure: DAP and Mean Arterial Pressure: MAP) by non-invasive (indirect) technique using a high definition oscillometric method. Blood pressure was measured in calm animals in lateral recumbency using appropriate size cuffs placed around the median artery of distal forelimb. The average of at least five measurements from each dog was recorded as the final blood pressure. Among breeds, higher SAP, MAP and DAP was recorded in Grey hound. Blood pressure was not influenced by age and sex. End organ risk categorization using value of systolic blood pressure revealed that out of 170 dogs, 42.35%, 20.59%, 31.18% and 5.88% dogs were at minimum risk, mild risk, moderate risk and severe risk respectively. Routine blood pressure monitoring using high definition oscillometer could be helpful in preventing cardiac and renal diseases by assessing end organ risk categorization.
HIGHLIGHTS:
© Blood pressure in Grey hounds breed was higher as compared to other breeds.
© Prevalence of severe hypertension was 5.88% and it was not influenced by age and sex in healthy dogs.

Blood pressure (BP) is the force that blood exerts against any area of the arterial wall, generally measured in mmHg (Brown et al., 2007). Systemic arterial BP can be divided into 3 components: systolic arterial BP, mean arterial BP, and diastolic arterial BP. Arterial blood pressure is a common parameter evaluated in conscious and anesthetized animals for assessing the cardiovascular status of an animal and monitoring of disorders such as heart disease, renal disease, and endocrinopathies (Skelding and Valverde, 2020). Although, direct blood pressure measurement (invasive method) is considered as the gold standard method, but it is not convenient in routine clinical practice (Stepien and Rapoport, 1999); so the indirect technique using an oscillometer (non-invasive) makes routine clinical blood pressure measurement practicable in dogs.
High definition oscillometric BP monitors introduce a new technology for non-invasive measurement of arterial BP which can measure BP more accurately than standard oscillometry (Egner, 2015). It has been evaluated in a few veterinary species like anaesthetized dogs, horse...
