Comparing blood pressure obtained using routine blood pressure sphygmomanometer to a non-invasive device that continuously monitors central blood pressure (CareTaker).

Application of Caretaker device to subjects that are scheduled for elective surgeries.

As per blood pressure monitor validation guidelines, the primary outcome measure will be the average difference in systolic and diastolic blood pressure measurements between the investigational device (Caretaker) and the reference (brachial cuff). In line with the ANSI/ISO/AAMI guidelines, we will obtain multiple investigational-reference measurement pairs in each subject (every 5 minutes during the surgical case) and will average the difference over all pairs from all subjects.
