Invasive blood pressure was measured from a dorsal pedal artery. DOP and POP device probes were placed over the median caudal artery with a flow-occluding cuff for noninvasive blood pressure measurement. Systolic arterial pressure measured by DOP, loss of pulse oximeter plethysmograph (POP<jats:sub>L<\/jats:sub>), and return of pulse oximeter plethysmograph (POP<jats:sub>R<\/jats:sub>) were compared to SAP measured by IBP. A linear mixed model was used to determine correlation. Bland-Altman analyses were performed to determine bias, SD, and limits of agreement. The accuracy of DOP and POP was compared to IBP across different tensive states.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sc_a4\">\n<jats:title>RESULTS<\/jats:title>\n<jats:p>Conditional <jats:italic>R<\/jats:italic><jats:sup>2<\/jats:sup> values for DOP, POP<jats:sub>L<\/jats:sub>, and POP<jats:sub>R<\/jats:sub> versus IBP were 0.92, 0.85, and 0.87, respectively (all <jats:italic>P<\/jats:italic> &lt; .001). The biases for DOP, POP<jats:sub>L<\/jats:sub>, and POP<jats:sub>R<\/jats:sub> compared to IBP were +7.6 \u00b1 13.1, +3.9 \u00b1 14.4, and +8.6 \u00b1 15.2 mm Hg (bias \u00b1 SD), respectively. Limits of agreement (lower, upper) were (\u221218.1, +33.3), (\u221224.3, +32.1), and (\u221221.2, +38.4) mm Hg for DOP, POP<jats:sub>L<\/jats:sub>, and POP<jats:sub>R<\/jats:sub>, respectively. DOP and POP overestimated SAP during hypotension (SAP &lt; 90 mm Hg), DOP to a lesser magnitude.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sc_a5\">\n<jats:title>CLINICAL RELEVANCE<\/jats:title>\n<jats:p>DOP measured from the median caudal artery may be acceptable for SAP measurement in dorsally recumbent, healthy anesthetized dogs &gt; 10 kg.
