Agreement between direct, oscillometric and Doppler ultrasound blood pressures using three different cuff positions in anesthetized dogs

Comparison of two species‐specific oscillometric blood pressure monitors with direct blood pressure measurement in anesthetized cats

“…In the present study, all OBP devices provided unacceptable SAP estimations regardless of the site of cuff placement. The large discrepancies found for oscillometric SAP estimations in the present report have also been reported for other OBP devices in dogs and cats, suggesting that the algorithms used for SAP calculations are the reason for disagreement between SAP measured by OBP and IBP monitors. However, it is known that SAP recorded by the direct method differs according to the site of measurement, with progressively increasing SAP values in more peripheral arteries due to the phenomenon of wave reflection .…”

“…The proximity between oscillometric MAP and DAP with their corresponding values recorded invasively has also been reported for OBP monitors from different manufacturers in dogs 11,17 and cats. 18 However, these results are in contrast with another clinical study which found that one of the handheld oscillometric devices that were evaluated in the present report was not recommended for clinical use in cats undergoing surgery.…”

Effects of intravenous and topical laryngeal lidocaine on heart rate, mean arterial pressure and cough response to endotracheal intubation in dogs

“…In the current study, oscillometric measurement of MAP was used as it has been reported to closely correlate with measurements obtained using invasive blood pressure measurement over a wide pressure range in dogs (Garofalo et al. ). Although Doppler ultrasound is known to potentially underestimate systolic blood pressure during conditions of high blood pressure (>140 mmHg) (Garofalo et al.…”

“…Although Doppler ultrasound is known to potentially underestimate systolic blood pressure during conditions of high blood pressure (>140 mmHg) (Garofalo et al. ), Jolliffe et al. () compared systolic blood pressure changes between groups rather than absolute values and thus the effect of underestimation may not be significant.…”

Comparison of medetomidine—morphine and medetomidine—methadone for sedation, isoflurane requirement and postoperative analgesia in dogs undergoing laparoscopy

“…There is conflicting evidence regarding the performance of the noninvasive Doppler technique compared with invasive blood pressure monitoring in anaesthetized and awake animals (Garofalo et al 2012;Seli skar et al 2013;Vachon et al 2014). However, both baseline and postoperative SAPs in this study were high.…”
