“…To overcome these difficulties, a high-definition oscillometric technique has been developed. This method shows limited agreement with measurements obtained by invasive methods in anaesthetised dogs (Seliškar and others 2013) and awake cats (Martel and others 2013), or when using the Doppler technique in anaesthetised cats (Petric and others 2010); however, it is being increasingly used in small animal clinics.…”

Anaesthesia – a reversible and controlled coma-like state – is an art based on an understanding of many contributing factors: pharmacology, the patient and its varied physiological processes or disease states, the procedure being undertaken and the potential complications arising as a result of all of these. Monitoring a patient at this time can be challenging but the increasing use of multiparameter monitors reduces the incidence of morbidity and mortality in both people and animals. Understanding the data displayed on these monitors is important, but it is vital not to lose sight of the whole picture as well. This article focuses on the main parameters that are monitored when small animals undergo general anaesthesia (including the patient itself) and explains how the data acquired should be considered in relation to other information.

“…13,14 More studies are needed to evaluate HDO, including studies comparing HDO results with values obtained via direct arterial blood pressure monitoring. These methods are technically easy to use and require relatively inexpensive equipment but are prone to error, include accurate readings of values from 5 to 300 mm Hg and highspeed analysis that allows for measurements at heart rates of up to 500 beats/min and during arrhythmias.…”

“…In cats, only one evaluation study of HDO has been published at present. 5 This evaluation was performed by comparison of measurements obtained by a Doppler ultrasonic device with direct BP measurements undertaken in anaesthetised animals. The authors concluded that discrepancies between the techniques were achieved.…”

This study compared indirect blood pressure measurements using a non-invasive method, high-definition oscillometry (HDO), with direct measurements using a radio-telemetry device in awake cats. Paired measurements partitioned to five sub-ranges were collected in six cats using both methods. The results were analysed for assessment of correlation and agreement between the two methods, taking into account all pressure ranges, and with data separated in three sub-groups, low, normal and high ranges of systolic (SBP) and diastolic (DBP) blood pressure. SBP data displayed a mean correlation coefficient of 0.92 ± 0.02 that was reduced for low SBP. The agreement level evaluated from the whole data set was high and slightly reduced for low SBP values. The mean correlation coefficient of DBP was lower than for SBP (ie, 0.81 ± 0.02). The bias for DBP between the two methods was 22.3 ± 1.6 mmHg, suggesting that HDO produced lower values than telemetry. These results suggest that HDO met the validation criteria defined by the American College of Veterinary Internal Medicine consensus panel and provided a faithful measurement of SBP in conscious cats. For DBP, results suggest that HDO tended to underestimate DBP. This finding is clearly inconsistent with the good agreement reported in dogs, but is similar to outcomes achieved in marmosets and cynomolgus monkeys, suggesting that this is not related to HDO but is species related. The data support that the HDO is the first and only validated non-invasive blood pressure device and, as such, it is the only non-invasive reference technique that should be used in future validation studies.
