Continuous Non-Invasive Blood Pressure System Data Collection in Comparison to Invasive Radial Arterial Pressure

On a first visit a screening procedure to verify inclusion / exclusion criteria are met will be conducted. On the primary procedure visit, data collection will begin with the subjects having the investigational device, ECG sensors, and 1 or more pulse oximetry sensors placed on them for data collection and to monitor their safety for the duration of the study. A physician will place an arterial line in the radial artery. The Sensifree cNIBP system will be calibrated with an oscillometric and/or auscultatory blood pressure cuff measurement taken on the arm opposite the arterial line. A series of blood pressure changes will be induced, including various combinations of methods.
