About

This study will compare accuracy of a newly developed monitor for continuous non-invasive blood pressure monitoring (CNAP™ Monitor 500; CNSystems Medizintechnik AG, Graz, Austria) that provides beat-to-beat BP readings with two of the current and more commonly used intermittently oscillometric non-invasive blood pressure device (NIBP), and the invasive arterial line (IBP).
