This is a multicenter, multi-phase, prospective, non-randomized, self-controlled, observational study to evaluate the validity of Philips non-invasive blood pressure technology.~This study is designed for the purpose of establishing equivalence of the Philips NIBP system with the gold standard arterial line.~Main Phase will be considered complete when the number of pre-defined subjects and data points are achieved per subject group.~Subject Group 1: Neonates, Infant, Children <3 years of age Minimum of 24 subjects and 180 data points~Subject Group 2: children 3-12 years of age Minimum of 41 subjects and 205 data points~Subject Group 3: Adolescent/Adult >12 years of age Minimum of 124 subjects and 620 data points
The purpose of this study is to compare measurements of blood pressure (BP) between the Philips non-invasive blood pressure (NIBP) system (including NIBP cuff and portable patient monitor) and invasive radial arterial line (A-line) in critical care patients.
