level, which could affect the condition of DBP estimation
with HDO.
Conclusions
When compared with the gold standard method for BP
measurement in conscious animals, HDO measurement
of SBP met the validation criteria of the ACVIM consensus panel, supporting the sensitivity and the robustness
of this method. For DBP, HDO tended to provide mild
underestimations, which may be 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. However, it
should be stressed that these results were obtained in
only six cats, and therefore the findings need to be confirmed in a larger
number of animals. In addition, the
cats involved in the present study were accustomed in
advance to the measurement methods and were handled regularly.
This feature differs from standard clinical practice where
patients undergo blood pressure
measurement less frequently. Therefore, the influence
of acclimatisation and handling should be checked in
clinical patients.
