OBPM_HARMONY: Physiological Data Recording Over 24 Hours Using the Continual Optical Hilo Blood Pressure Monitor and an Ambulatory Blood Pressure Monitor

During study Visit 1, participants are equipped with tthree devices- the Device Under Test (Hilo band), the reference device (Ambulatory Blood Pressure Monitor), worn on the opposite arm, and a Hydrostatic pressure monitor on the chest. Subjects are instructed to wear the three devices for the next 24 hours to collect blood pressure (BP) and heart rate (HR) data as well as hydrostatic pressure measurements. After Visit 1, subjects return home with the devices in place. Visit 2 takes place at least 24.5 hours later, when participants return to the site to hand back the equipment.
