Evaluation of agreement between invasive and non-invasive blood pressure measurement using the PetMAP

Background: Measurement of arterial blood pressure is recommended in anaesthetized animals to guide perioperative treatment. Invasive blood pressure measurement is considered the gold standard, however it is also technically challenging, requires specialised equipment and carries certain risks. For these reasons, non-invasive blood pressure measurement devices are commonly used and are expected to provide accurate and reliable results. This requirement is particularly true for rabbits, in whom peri-anaesthetic hypotension is commonly observed and in whom perioperative mortality remains disproportionally high. Several authors have compared different non-invasive devices with invasive measurements in rabbits and have reported contrasting results. However, to date no comparison between invasive measurements and the PetMAP Aim and hypothesis: The aim of the study was the comparison of invasive blood pressure measurement with PetMAP Materials and methods: Sixteen client-owned rabbits presenting for various surgical interventions were included in the study. Invasive measurements were performed by cannulation of an auricular artery. The PetMAP Results: Data collected from 16 rabbits were used for statistical analysis. In the clinical setting, the PetMAP Conclusion: The PetMAP
