Evaluation of agreement between invasive and non-invasive blood pressure measurement using the PetMAP™ device in rabbits

Background Measurement of arterial blood pressure is recommended in anaesthetized animals to guide perioperative treatment. Invasive measurement considered the gold standard, however it also technically challenging, requires specialised equipment and carries certain risks. For these reasons, non-invasive devices are commonly used expected provide accurate reliable results. This requirement particularly true for rabbits, whom peri-anaesthetic hypotension observed mortality remains disproportionally high. Several authors have compared different with invasive measurements rabbits reported contrasting However, date no comparison between PetMAP ™ device, that has been designed specifically veterinary medicine, reported. Aim hypothesis The aim study was rabbits. We hypothesised would show acceptable agreement according American College Veterinary Internal Medicine guidelines. Materials methods Sixteen client-owned presenting various surgical interventions were included study. performed by cannulation an auricular artery. cuff applied distal elbow manufacturer’s each , three values recorded. mean one value measured . Results Data collected from 16 statistical analysis. In clinical setting, device showed significant overestimation systolic, diastolic pressure, which addition, bias not constant, implying poorly predicted changes pressure. Conclusion did meet any recommendations.
