Horses where invasive blood pressure measurement from the thoracic aorta (Ao) was available (n = 4). QH = Quarter Horse, TB = Thoroughbred
Table 2: Comparisons between mean arterial pressure (MAP) measured non-invasively via oscillometric technique (NIBP) at the tail with a goal cuff width-to-tail circumference ratio of 0.25 and measured invasively in the metatarsal artery (MT), facial artery (FA), and transverse facial artery (TFA) in dorsally recumbent, anaesthetised horses when individual height correction factors and a standard heart level correction of 27 mmHg were used (n = 9 horses). The mean difference with 95% confidence intervals (CI) and p values are presented. An asterisk indicates equivalence with a mean difference and 95% confidence interval within ± 5 mmHg and p > 0.05 as determined via linear mixed model analysis (n = 257 paired comparisons with each peripheral site).
