Evaluation of indirect blood pressure monitoring in awake and anesthetized red-tailed hawks (Buteo jamaicensis): effects of cuff size, cuff placement, and monitoring equipment

Comparison of three different inhalant anesthetic agents (isoflurane, sevoflurane, desflurane) in red-tailed hawks (Buteo jamaicensis)

“…Direct and indirect blood pressure values have been reported in awake and anesthetized red‐tailed hawks (Zehnder et al. 2009).…”

“…2009). In one study, Doppler systolic blood pressure measurements (mean ± SD) were 190 ± 38 mmHg in awake red‐tailed hawks and 155 ± 27 mmHg in normotensive sevoflurane anesthetized hawks (Zehnder et al. 2009).…”

“…However, Zehnder et al. reported that Doppler measurements derived from red‐tailed hawks more closely reflect mean arterial blood pressure than systolic arterial blood pressure (Zehnder et al. 2009).…”

“…2008; Escobar et al. 2009; Zehnder et al. 2009) and literature comparing the use of isoflurane and sevoflurane in birds is scarce.…”

Monitoring

“…In the same study, the Doppler NIPB measurement tended to underestimate the SAP at all sites of cuff placement, but doppler was a good predictor of the MAP (Zehnder et al 2009). Many factors can affect the accuracy of NIBP measurements, including the monitor itself, the site of the cuff placement, the cuff size, and the blood pressure itself (Dorsch & Dorsch 2008).…”
