We have a fetal monitor that the NIBP says motion and will not read the blood pressure half of the time. We have tried calibrating the NIBP and swapping out the NIBP board, but the issue was still there. It seems to have more issues with the extra-large cuff. I only got the motion error a few times while hooked up to my simulator with an extra-large cuff, but everything was sitting still. Has anyone ever seen an issue like this or solved this problem?
