Summary

The purpose of this project is to compare the performance and validity of novel wearable technologies that measure blood pressure (BP) and physical activity with a Spacelabs Ambulatory Blood Pressure Monitoring (ABPM) device.

Detailed description

The investigators will recruit community-dwelling participants to wear novel cuffless BP monitoring devices for comparison with a Spacelabs ABPM device throughout a 24-hour period. The identification of accurate cuffless BP technologies would greatly improve access to ABPM and allow for BP measurements at times when the use of cuff-based devices are not feasible. Knowledge from this project will inform subsequent research protocols among adults and under-represented groups. Up to 250 participants (at least 100) will be involved in this study each wearing up to 7 devices (6 BP devices and 1 activity monitor). The assignment of devices will be randomized by day and by the arm or wrist on which they are worn. During the first visit, participants will provide their consent and be randomly fitted with 3 BP devices; either the Spacelabs ABPM device or the ABPMpro device, the Aktiia wristband BP monitor, and one of two other cuff-based wrist BP monitors, along with an activity monitor to track body positions. These devices will be worn continuously for at least 24-hours, including overnight, before being returned. On the following day, for Visit 2, participants will be fitted with a different set of 3 BP devices; the ABPMpro device or Spacelabs ABPM device, the Aktiia wristband BP device (on the opposite wrist from the previous day), and the final cuff-based wristband BP device. Additionally, participants will wear an ambulatory BP device as a patch on the chest. These devices will also be worn for at least 24 hours. This study will enable characterization of the feasibility, practicality, and effectiveness of the measurements and the devices\' accuracy and precision.

Interventions

Type	Name	Description
DEVICE	ABPMPro	This is an upper arm, cuff-based intermittent ambulatory BP device. This device has an internal activity and body position sensor which gathers information about sleep-wake estimation.
DEVICE	Spacelabs Ambulatory Blood Pressure Monitoring	This is an upper arm cuff-based device with tubing for continuous ambulatory BP monitoring with a unique activity sensor that correlate with patient movement activity with blood pressure changes.
DEVICE	Aktiia Blood Pressure	This is a wrist cuff-based device which uses an optical sensor (photoplethysmography sensor) to gather data from the arteries under the skin surface. Aktiia has an upper arm cuff device which is used for calibration once every month to provide a baseline blood pressure reading.
DEVICE	LiveMetric	This is a wrist cuff-based applanation tonometry continuous ambulatory BP device. This device has automatic self-calibration and comes in various sizes.
DEVICE	Bpro	This is a wrist cuff-based wireless oscillometric, continuous ambulatory BP device. It has applanation tonometry at the wrist with Pulse wave analysis. This device needs calibration with a brachial cuff BP measurement.
