NIBP Validation Study

All subjects enrolled in this study will receive one Philips non-invasive blood pressure cuff. This cuff will be connected via compatible hose to the Philips IntelliVue X3 monitor hosting the released or investigational NIBP algorithm. The invasive blood pressure from the radial arterial line will also be connected to the Philips IntelliVue X3 monitor. The Philips IntelliVue X3 monitor will in turn be connected to a laptop for data collection.
