  1. Systolic, mean and diastolic arterial pressure measured with an oscillometric method were compared to an arterial blood pressure measured invasively by central ear artery cannulation. Overall pair include all the value measured while the hypotension subgroup include all the pair measurements that had a systolic or mean invasive arterial blood pressure lower than 80 and 60 mmHg respectively. IBP invasive arterial blood pressure; NIBP non-invasive arterial blood pressure. Values are expressed as mean ± standard deviation
