A newly developed monitor for continuous non-invasive blood pressure monitoring (CNAP™ Monitor 500; CNSystems Medizintechnik AG, Graz, Austria) provides beat-to-beat BP readings and is non-invasive. To make sure that anaesthesiologist can rely on and make clinical decisions based on values provided by the CNAP™ monitor, to demonstrate its reliability we will test it during the perioperative care of children.
