Non-Invasive Blood Pressure Monitoring

Patients having either elective cardiac surgery or elective neurointerventional surgery will have blood pressure monitored by the ClearSight device, along with the standard of care radial arterial line, throughout their surgery. The arterial line will be placed on the radial artery contralateral to the upper arm blood pressure cuff. The ClearSight device will then be placed on the third finger of the hand ipsilateral to the radial arterial line.
